I am of two minds on this book.

Mind One: So Isaku is attempting to distance herself from her (loving) yakuza family in hopes of having actual friends and possibly a boyfriend...and the twenty-six-year-old who has been taking care of her since she was five has a panic and enrolls in her high school alongside her to keep her...safe. Riiiight. That's what his goal is. So not only do we have unsettling aspects of wife-raising, but also a guy who absolutely comes off as a predator. Who cares if she's got a crush on him she's trying to get over - this is creepy.

Mind Two: Creepy as it can come off, there's also something really funny about a twenty-six-year-old dude loudly proclaiming that he's a sixteen-year-old, and people taking him at his word. And you know what? Isaku is dangerously naive and has roughly zero idea how not to get herself into trouble. She kind of needs a babysitter at this point, and if we suspend our disbelief, he's also actually no creepier than your average shoujo hero. If I can enjoy other age-gap manga, why not this one?

Which mind will win out? I guess we'll find out after volume two.

A Girl & Her Guard Dog depicts the story of 15 years-old Senagaki Isaku, the granddaughter of a notorious yakuza. All she wants is to have a normal life, make friends, go to high school like any normal teenager and why not have a boyfriend. Of course, all of this is complicated when everyone is scared of your family. Since her high school is an hour away from her home, Uto Keiya (26), her grandfather’s first lieutenant decides to attempt her high school as well to protect her (of course!) of dangers (aka men).

For some unknown reason, I keep picking up Hatsuharu’s series whenever they get translated into English even though there isn’t one of them that I’ve actually like. This one was no exception.

In my opinion, this manga has two problematic issues. The first one being the weird age gap between the two main characters. Isaku is 15 while Keiya is 26, she is a teenager while he is a grown ass man! I can’t fathom how the author could think that it was a good idea. I keep seeing lately manga with those kinds of age gaps (yes, I’m talking about you Mikami-sensei's Way of Love) and I wish it would stop because it keeps romanticizing those kinds of relationships while there is nothing remotely romantic here.

What’s even more problematic, and that’s when the second issue comes in, is that Keiya raised Isaku since she lost her parents and therefore became the parental figure. “I’ve pretty much raised you, and I’ve never been prouder”, Keiya acknowledges it. He raised her as she was his kid or sibling and yet, they will have a romantic relationship later on. It’s problematic on so many levels and I just can’t recommend this manga to anyone.

Pretty art, but the story was just one big ick. The age gap (she is 15/16 he is 26), how he treated her as a bit like a pet-daughter combo along with maybe more given how he also couldn't keep his hands off her in a way that isn't how you would act with someone you raised from kid to now, along with totally going into her life (as a classmate, eww) and then also dictating what she can and cannot do. Any boy get close to her gets anger and more. He raised her from when she 5, it is just not OK. Especially when you know that this is shoujo... so they will end up dating. URK. No thank you. I am out.

Free to read on Amazon JP until 6/02 Vol 1 and 2

I got drawn in by the age gap... Mangas never have that.

The drawings were cute, the hero was sweetly J/P and the heroine was prettily gloomy.

Some humor, kinda? I definitely aged out of this sort of mangas, though.

The fact that he's 26 and she's only 15 makes this SO UNCOMFORTABLE to read

This manga was very interesting I liked the characters and story very much it has been awhile since I have read a manga like this one. The characters were interesting I especially liked Isaku and Keiya both were great in their own ways made for an interesting dynamic. I liked Isaku for her want to separate herself from her Yakuza family to have a normal school life I liked Keiya for his protectiveness he would do most anything for her. The story was great it starts as Isaku goes to a school farther from her family to try and have a normal life although Keiya goes there too to protect her pretending to be younger than he is to be there some things happen looking forward to where the story goes next.

I just can't. Age gap - I'm in. But not 10 years including a minor.
She is 16, he is 26.


He has been knowing her since she was 6, which is another Level of creepy.

Plus, again, we have a character not respecting the boundaries of another character, all because of "safetey". Yeah, sure, more because of your jealous, creepy ass.

High 3 stars. I am in love with the art. The story is okay. The age gap is a bit much, but "eh". Didn’t bother me too much.

School Life With the Yakuza

After the death of her parents Isaku is taken in by the local Yakuza and raised as a part of the family. However being related to a criminal organization tends to make people nervous so the poor girl soon finds herself with friends among her classmates in middle school. So when the opportunity comes to get chosen by a high school (Japanese HS is like college state side) she goes to one far from the people who have raised her and were responsible of her friendless school life. Little does she know the over protective man that help raised her has pulled some strings to get enrolled as a student at the same school so the young princess will be protected.

Now to be fair this manga can be taken as a bit on the creepy side considering the the young missus just entered high school so that would put her in the around 16 years old range but last I checked that is the age a girl can choose to wed in the country legally. Of course there is the consideration of Isaku's guardian (aka the Guard Dog, 26 year old Keiya) that she has shown to have feelings for could be considered creepy too considering he basically raised her in the Yakuza after her parents died (grandpa had a lot on his plate I guess) and goes so far as to take the drastic actions of enrolling as a student regardless of how old he looks. If he took on the role of just being her parent I think it might be a little more weird than as a childhood friend (which is technically true too though he was much older) when he begins to realize the princess is not just a little girl anymore.

Now that said Keiya continues to help Isaku in any way he can to make adjustments in her new life away from many of the Yakuza but at one point I started thinking regardless of strings pulled the thought of a 26 year being enrolled as a student is kind of silly and perhaps becoming a teacher would make for an interesting story dynamic but if the two of them go from guardian and ward to romantic relations then that kind of position would have its own problems (besides the series becoming Nisekoi mixed with Great Teacher Onizuka.) As a first volume this manga has potential for both trouble and perhaps something cute so only time will tell.

I like the storyline of this. I think the art is beautiful and it has a good amount of comedic moments. However, the fact the male lead is 26 yrs old and is pretending to be a high school (of course to protect the protagonist) and the protagonist is possibly 15 at most is weird. At least to me.

She is not even legal to have a relationship with him. If he was around her age (even 18) or she was in college, I wouldn't have such a problem with it. Still, if you don't mind age gaps like this with mafia/yakuza, romance and humor influences- you will probably love this story.

Only in a manga it would make sense for a 26-year-old guy to pass for a 16-year-old student without raising any suspicion at all lol

I have a problem with the age gap. I feel guilty for reading this. When I was younger this wouldn't have bothered me - strange to say - but as I have gotten older it's a glaring red sign.

I picked this series up as it's been sitting on my to read list for a while.
I ended up devouring this series in 24 hours. It's sparked the whole mafia romance kick for me. I enjoyed the innocent relationship between our main characters and can't wait for the next one in the series to come out. The artwork is really well done.

(Number 8 of 37 from the Kodansha Amazon sale)

There was nothing particularly interesting or exciting in this manga. As a romance manga it was pretty despicable for even suggesting an age-gap romance between a 15 year old girl and her 26 year old (essentially foster father) father figure. As a high school manga it was very dull with all the classmates serving as background noise to the failure that was the romance.

It was just odd, the art was sub-par, and the romance was very, very strange. I had to trundle through it at the very slow pace the plot moved at and hope for the ending to come sooner rather than later.

A Girl and Her Guard Dog, Vol. 1 ⭐⭐⭐⭐

One of these things is not like the other…

Isaku Senagaki and Keiya Uto are first-year high school students...perfectly normal on the surface. Except Isaku is the 15-year-old granddaughter of a yakuza boss and Keiya is her grandfather’s first lieutenant, is actually 26 years old (posing as 16), and is her personal bodyguard.

Isaku went to live with her grandfather at the age of five after her parents died in a car crash. Keiya was already living there and after seeing how distraught she was, promised to become whatever she needed in order for her to be happy, leading them to have a sort of parent/child, big brother/little sister kind of relationship. On his end, at least. For Isaku, she’s been in love with him for a very long time.

Growing up in a yakuza family caused Isaku’s life to be quite lonely, none of her classmates wanted to get involved with someone associated with such dangerous people. So Isaku decides to enroll at a high school an hour away, where nobody knows her or her family, and where she can finally live a normal life. She wants friends and she wants a boyfriend, because obviously her unrequited love for Keiya isn’t going anywhere. Still, what she wants more than anything is for Keiya to finally stop viewing her as a child.

On her first day of school, she gets a shock - Keiya has enrolled, too (he pulled some strings), with the approval of her grandfather, because neither wants her dating...though I’m sure each man’s reasons for why that is differ greatly. Friends, sure. Boys, that’s not only a no, but a hell no for Keiya.

Keiya almost instantly becomes popular, which leads to a panel that literally made me laugh out loud when the mangaka had to remind the reader that Isaku, who’s socially stunted, is the main character. Still, he encourages her to come out of her shell and she finally starts some tentative friendships. Then a boy comes along and gets Isaku’s number and that’s when we see the “guard dog” come out! I think the author did a really good job of conveying Keiya’s two sides - the soft side he shows Isaku, and the dangerous yakuza he actually is.

It’s obvious throughout the volume that Keiya is very protective over Isaku, making it clear she’s the most important person to him. She interprets that as being because they’re all part of “the family”, though. However, when Isaku becomes excited over finally making friends, it seems to sadden him a little that she doesn’t consider him a friend as well.

With their age gap and relationship growing up, I don’t think Keiya sees her as more than family or a friend through most of this volume. Yeah, he’s affectionate with her, is literally willing to kill for her, and feels protective...maybe even possessive over her. However, I don’t think it really hits him that she’s matured (as in, she's not a small child anymore; she's definitely still naive) until the very end after declaring he’ll never let another man take her away from him. She brushes it off as him just doing his usual overprotective schtick, but after she dozes off, he mutters that “this complicates things” and then the volume ends. Sooo...yeah, could be he’s starting to develop romantic feelings for her. Or at the very least, is becoming confused about how he feels about her.

I genuinely laughed multiple times while reading this volume, not only over Keiya’s antics, but the volleyball practice at home was a good scene, too. One negative I noticed was that there are several editing errors, though I think they were mostly toward the beginning. I’m not sure where this series is going to go, but I imagine wherever that is, it’ll be getting there slowly considering their ages. It’s not my usual preference (slow burns, that is), but I enjoyed reading this volume so much that I’m definitely planning on picking up the next one.

On the one hand, very good portrayal of the massive maturity and intellectual gap between teenagers and adults and a very healthy reminder that teenage girls have no business with men in their 20s+

However, I adore this trope in fiction and I'm a sucker for a yakuza romance so listen...in real life "non" in books "Oui oui".

Keiya is hot, super nice all while also being a scary gangster and the premise of him pretending to be a high school student when it's very obvious he is not is ver ver funny to me. I wish the main character wasn't such a hopeless cry baby but also I was definitely a hopeless cry baby at that age so feels authentic.

4 "don't date your teenage ward"s out of 5 "or do but only in my romance manga"s

I’m very surprised that they officially translated this book, considering the troubling aspects of the age difference. I know that will bother quite a few people, but I’m ok with things.

I was particularly happy to read this volume because several of these chapters weren’t available as fan scans. So I finally got to fill in the missing pieces of how she made friends and how they became class reps. I will add that having read the first chapter again, it is kind of amusing how busty she suddenly becomes.

I really liked the drawing style and the fast pace of the story.

The reason why I gave 3 out of 5 stars is that I can't pass by the fact that it's a romance between a 15-year-old girl and a 26-year-old young man...

Plus, whereas I appreciated the fact that the female protagonist was able to maintain somewhat of an innocent character, you would think that a yakuza boss' granddaughter would be able to protect herself to some extent.
Isaku-san is very determined to enjoy high school life like a normal teenager, but she's just way too naïve for me.

Isaku's being raised by her grandfather, who is a mob boss. Her constant shadow (and body guard) is Keiya, who wants to protect her from everything, including high school boys. Despite being 10 years her senior, Keiya enrolls at her school and joins her class, the better to keep an eye on her. His protectiveness and possessiveness might be duty ... or they might be something more.

Yakuza and a slightly taboo first love.
