I’m a big fan of Beastars, so I jumped at the chance to read this volume! I enjoyed it so much that I feel like I read it in the blink of an eye, and it’s a rather think volume.

Our protagonist, Ao, is a high school girl who is a bit of a loner. She’s bullied at school and doesn’t really talk to her classmates, but she doesn’t seem all that perturbed by it. After all, waiting for her at home is her beloved pit bull Taika, as well as her loving father. The family dynamic we’re introduced to in the first chapter was just so lovely…so it was all the more gutting when it was ripped away.

After seeing just how much of an impact her father and pet have on her life, for her to come home to her beloved dog licking the mawled-off face of her deceased father… While I knew it was coming, it didn’t stop the shock. And that’s coming from someone who reads a lot of horror. From here, Ao has a big decision to make: report her dog and know he will inevitably be euthanized, or hide the body along with the crime and continue living on with her dog. Honestly, I can’t judge her for the actions she took after finding her father’s body. I mean, it’s her father—there’s no way she wasn’t in a complete state of shock.

Thankfully Ao isn’t left without any parents after the incident, as her mother was away on a work trip at the time. Sadly it doesn’t seem like the two have the best relationship, as she jumps at the chance to humanize Taika—something her husband and daughter were very vocally against.

Once Taika is humanized, he enters an interesting state of “dog-minded with human emotions”. Just the psychology behind how a dog would learn to manage human emotions is interesting enough, but surprisingly it seems like there’s no real orientation from them judging on how Taika behaves. We know he has all his memories from his time as a dog and he still deeply loves Ao, but he says some rather inappropriate things at times. More than anything, it seems like it’s up to the other humanized animals to keep others in check, as many humans still see them as pets.

Going back to the mystery behind Ao’s father for a moment, this is the plot that is currently moving the story forward. Taika’s humanization is just a byproduct of Ao’s mother hoping for a witness to her husband’s surprise disappearance. While Taika was indeed licking the corpses face at the beginning of the story, as he has the short term memory of a dog, not even he knows if he actually did it. Unfortunately for Ao, he was somehow able to remember the two of them disposing the body in a river.

I wonder if Taika’s memories will begin to come back as he grows more comfortable in his human body? I worry about his actions, as they’re still very much the actions of an intensely powerful dog who doesn’t know his own strength. While that may be cute and forgivable in a dog’s body, the same can’t be said in a massive dogperson’s body.

The reason why Paru Itagaki is in my top 3 favorite Mangaka (along with Hirohiko Araki & Tsubasa Yamaguchi, if you must know) is because of one thing all three of these authors do: commit. No matter the level of absurdity, grotesqueness, shock value, things that some readers would find distasteful, strange, unappealing, or overall not suitable for the mainstream -- Paru Itagaki especially doesn't pull any punches.

And this is what makes ALL of her manga so utterly wonderful to me. If the concept in this book was done by literally anyone else, it wouldn't work whatsoever. But her fearlessness in her writing, her lack of shame, this gooey, emotional heart wrapped up in hard-edged, bloody mystery -- it's just perfection. Itagaki-sensei, I will follow you till the ends of the earth.

What an insane premise for a book, but what else would I expect from the creator of Beastars lol. I'm intrigued by the mystery though. I'm just really hoping there isn't a romantic relationship between this girl and her humanized dog.

In a world where the human population has declined to the point of humanizing pets– a procedure turning the pet into a humanoid cat- or dog-person – our main character comes home one day to find her pit bull standing over the mutilated body of her father. Afraid that he will be put down, Ao covers up the death so that she will not lose the only other person she cares about. Then Taika gets humanized and the whole plan looks like it might be doomed.

I have thoughts. I want to start off with the fact that the art, of course, is amazing. I love the art style of Beastars and think that it is super expressive, unique, and works extremely well for the particular feel of this story. There is this kind of strange seesawing between the reader being afraid of Taika and then seeing him acting goofy like a normal dog. I think that fits very well with the story because it’s a constant thought of “Did he actually kill Ao’s dad?” and “No, he couldn’t have look at how sweet and dumb he is.”

The writing is also extremely well done. I like the abrupt tonal shifts. I like the characters a lot. I am intrigued and want to know more about the world and what happened to Ao’s dad. For example, are there other pets being humanized besides cats and dogs? What about pet birds? Lizards? Hamsters? Rats? It would be interesting to see that expanded on. And as a quick aside, I think it’s kind of funny how Ao is all worried about losing the TWO people she cares the most about - her dad and Taika. What about her mom!? I thought the mom was dead until she suddenly showed up with a humanized Taika.

And now to the not so great things. There is a very strange and slightly off-putting sexual undertone to a lot of this. Which, to be fair, I expected on some level. But I didn’t expect it immediately, and I didn’t expect it to come off as creepy as it does. And, honestly, I don’t think it’s needed. Especially not this early. We have enough cool and interesting things going on without it.

This did bring my rating down a little and left me conflicted on if I am going to continue the series or not. Maybe the rest of the series will focus more on other things. That’s what I hope, because we have a really interesting set up here and a really cool world and some of these panels actually creeped me out. I’d hate for a few weird scenes to bring all of that down.

As always, a BIG thanks to Netgalley and VIZ Media for the DRC!!!

Manga | Humanized Pets | Middle School Setting

Thank you to Viz Media LLC for this ARC in exchange for my honest review!

• Plot:
Taika’s Reason Vol 1 starts off with a mystery behind what happened to Ao, the MC’s dad, then goes into a flashback. Her dad supports her ego and her outbursts about how she hates humans and the humanization of dogs as people. Something terrible happens, and the story unfolds from there.

• What I Liked:
The intro is strange and dark, hinting at realities that sometimes happen to pet owners. I also like Taika's height difference against Ao. He reminds me of Legoshi from Beastars.

• What Didn’t Work for Me:
Taika mentions he would rather mate with Ao than see her as his master, which is kind of cringe and borderline bestiality-like.

• Themes / Ideas:
What sometimes happens to an owner who passes with an animal around them, there's gore, lying, bullying, etc.

• Who I’d Recommend It To:
This manga might appear to those who like furries. It’s a little cringe because Taika asks Ao’s boyfriend whether he can watch them mate, so be aware. There are also graphic scenes where another dog asserts dominance over Taika and urinates on him. If you enjoyed Beastars, this is by the same creator.


• Overall Thoughts: Taika is a pitbull dog and gets humanized. In this universe, people choose to have pets over children, partly due to the decline in birth rates, so this might appeal to pet owners who view their pets as their babies and family. There’s some comedy where the dogs act like dogs still despite being humanized sniffing butts. Taika attends school with Ao, who is a middle schooler. Taika has a foe and tries to protect Ao. The art style is great, it’s really expressive. I'm curious what the next volume will hold.

Have you ever wondered what your pet was thinking/saying?
I can say I have, but also know there are times its probably better I don't.

First off, I am disappointed in Ao automatically assuming Taika is the one at fault for her fathers death. She blames him, but not once does she think rationally that maybe why Taika had blood on his face was because he was trying to nudge the father like dogs do to get attention. But I see there might be a shift later on when other situations arise.
There are so many moments where I just want to give Taika so many pets and hugs, he really is loyal and its heart breaking to see that he has to deal with the stereotype of being a pitbull. Especially when he is accused of doing something he didn't do. Hopefully, in the next volume there is some clues to what really happened.
I enjoy the fact that the author kept some of the animals traits when they become humanized. It makes it feel more realistic in a sense that while learning human customs they still have their natural instincts as well.

Summary:
In this world where the birth rate has declined, their solution was to humanize their pets. Some individuals are for it and as you can imagine others are against it.
After coming home to discover her father body and Taika (her dog) over top of it, Ao makes the decision to make it look like her father is just missing to save Taika- since he is a pit bull the stereo type would not help the situation. Although Ao just assumes Taika is the one who mauled her father and is willing to live with the secret. However, Taika get humanized and the truth may come out... but what really the truth?

Ich hab ein wenig gebraucht um reinzufinden, auch um mit den Charakteren warm zu werden. Anfangs war's noch etwas eintönig.. doch das hat sich sehr schnell geändert 👀 aber worum geht's? Wir lernen Ao, ihre Familie und ihren Hund Taika kennen - in einer Welt, in der die Geburtenraten sehr niedrig sind und Haustiere wie Hunde und Katzen in humanoide Hunde- bzw Katzenmenschen verwandelt werden. Klingt schräg? Fand ich auch 😅 doch nach und nach ist dieser Aspekt sehr interessant, auch wie er in die Story eingearbeitet wird. Man muss sich etwas dran gewöhnen, aber dann macht's immer mehr Spaß dem ganzen zu folgen. Doch nochmal kurz zum Beginn - denn Taika ist ja ein normaler Hund. Eines Tages kommt Ao nach Hause und er steht blutverschmiert über der zerfleischten Leiche ihres Vaters! 😱 Da die davon ausgeht, dass er ihn umgebracht hat, lässt sie die Leiche verschwinden, da sie nicht auch noch ihren geliebten Hund verlieren will.. ihrer Mutter und der Polizei erzählt sie, dass ihr Vater verschwunden ist und so beschließt die Mutter ihn zu humanisieren, damit er den Vorfall schildern kann. Doch ist das alles so einfach…?
Mehr will ich jetzt nicht verraten.. aber es ist tatsächlich viel spannender, als es zunächst klingt. Denn neben dem Drama rückt auch immer mehr der Krimiaspekt in den Vordergrund. Nach Band 1 kann man noch nicht viel sagen, aber ich frag mich schon, wie's denn weitergeht.. 👀

Thank you NetGalley and publishers for the digital ARC!

Having read Beastars, I picked up Itagaki's new work as soon as I saw it! I was a big fan of the art and storytelling of Beastars so I had high hopes for this work and it didn't disappoint! It starts off at a brisk pace with Ao's father dying and the only suspect at this time being her pitbull Taika, and we watch as Ao tries to cope with this fact and unveil the mystery of how her father died and who killed him. There's this whole process of Taika becoming "humanized" into a dog person (what he looks like on the cover), and we watch as he tries to fit into human society along with other dog & cat people. The premise is dark and carries a lot of moral conflict, and in this volume the author sets up potential obstacles to overcome in the future. Itagaki does a wonderful job of breaking up intense moments with comedy to lighten the mood. It's an intriguing and funny read, and I'd like to see how Taika assimilates to human society - or not!

With that being said, I was uncomfortable when it came to the sexual undertones of the series so far. Hopefully it's just considered inappropriate behaviour to be corrected by the humans in Taika's life. But if it continues on in future volumes I'm not sure I'll be able to keep reading. But for now, I look forward to the next volume!

I voluntarily read and reviewed this advanced copy via NetGalley. All thoughts and opinions are my own.

I always associate manga with my middle school years and the joy they brought me. It was usually shoujo, which is comics marketed towards girls. I read series like Peach Girl and High School Girls. Taika's Reason was a very interesting manga about the humanization of pets to combat the decreasing birth rates in Japan. After finding her father's corpse next to her pitbull, the heroine turns her pup into a human to avoid suspicion. This book had a slow build and I found my curiosity growing after every chapter. To see the former animals interact with the humans was rather intriguing. I'm glad there weren't any overt gross beastiality jokes, but there were still some intense sequences. I could be convinced to continue this collection considering it did leave on a cliffhanger. Even though the giant watermarks made it hard to read at times, Taika gave me a Reason to keep on going!

An insane concept that explores uncomfortable ideas and the psychological impact in a world where humans are turning their pets human. Lines are blurred in a society that's newly adjusting to account for these animal people.

Taika is off-putting the moment he turns human, because he's so freshly turned and doesn't understand how to integrate himself the way other dog people have. It leads to a lot of odd moments between him and the other characters, as well as between him and his owner, Ao.

I really like the setup and I'm invested in seeing his development, as there's a lot of room to explore the animal people and how they're treated. There's a sliver of it shown here through Taika and another side character, and I'm looking forward to seeing how Ao deals with solving the murder on top of it all.

Ao is a first year high schooler with a bad temper. But she loves her father and her pitbull Taika. When she finds Taika next to the mauled body of her father, she panics and gets rid of the body. She thinks she’s got away with it, but then her mother decides to humanise Taika, a process of making cats and dogs human-animal hybrids. Now Taika has the ability—and inclination—to tell what they did. If only he could remember properly.

This was slightly more grim than I assumed, though it has comic elements too. It takes mostly place in high school where both Ao and Taika are being bullied, the latter by humans and humanised animals both. Taika behaves mostly like an animal still. Ao will do anything to keep what happened to her father a secret. But it may be someone already knows. Art was fairly unique and good.

I received a free copy from Edelweiss in exchange for an honest review.

Ohh this mystery is so intriguing. Whether Taika actually did it is so 50/50, I personally thinking he saw Ao's Dad doing something very bad and reacted accordingly.

I think Paru is very good at themes of what makes someone human or not, I think we're going to see more from the animals perspectives about their conflicting feelings on being people. Because none of them gave consent, and I have a feeling this German Shepherd character is bound to have some conflict about it.

That being said, a few points were taken off for me for some of the scenes. I expected some weirdness going into this series. I've read the first couple of volumes of Beastars, I could accept it there, but there's already a lot going on with this series haha.

Thank you NetGalley and Viz Media for the arc.

This one really surprised me, but I ended up really having fun with it!

I really liked the sharp and expressive art style, and the actual plot ended up gripping me quickly - darkly funny with a tinge of suspenseful mystery.

For readers interested in:
Dark humour
Mild gore
Exploring dog personalities if they were human eg German shepherds being hard working
The manga/Netflix show 'BEASTARS' (the artists previous work)
Themes of bullying and teenage experiences in school

I loved this book. Humanizing animals is such an interesting concept. Then you have Ao dealing with the loss of a family member and then having the animal she thinks may have been responsible turned human adds such a complicated layer. I genially enjoyed this book, and I really enjoyed Taika’s personality. This is one of those graphic novels where the characters truly shine. I can’t wait to see what happens next.

I wasnt a fan of the art style but the plot is pretty interesting. I love the little mystery we get with her dad, it’s mixed in with comedy and action which I also enjoyed. The mild smexual tension between them was a bit strange but I read it without realizing the story was by the same author of Beastars lol

3/5 - overall rating
4/5 - plot
3/5 - art style

Absolutely ridiculous in the most delightful way. I requested an ARC because it looked strange and interesting, and I was not disappointed. The plot centers around a murder, a humanized dog, and, of course, high school drama. Really, what else could you ask for? Read this if you are into weird sci-fi, teenage angst, and surprisingly sexy dogs.

Okay, so I am a long-time Beastars fan, and Itagaki hit that same spot with Taika's Reason.

I can not wait to devour this series. I love the art, the internal monologue of Ao, and the personality of each character. It was the perfect length (even though I didn't want it to end). I will be reading this and picking up Beastars again.

I really enjoyed this manga and I like all the chatacters as well! I totally agree that pets shouldn't be humanized! But it's hard to admit that it's nice to be able to understand them. I felt like I learned a lot too!

This was an interesting read. I wasn't sure about the premise but I was hooked very quickly. This isn't what it seems on the surface if you're just reading the description. I don't want to spoil anything but I cannot wait to read the next volume and see where this goes.
