The plot thickens.

I've been on the fence a bit with this series, but volume four was a solid read. While the last two books have been very shojo fluff (nothing wrong with that at all), this story mixed in more of the political and social intrigue that volume one had. The story was good with fluff to balance out the more serious tons. There's still a heavy influence on the romance, but it feels like the plot is picking up more to tackle the xenophobia in the story's world, as well as the political tension between all of the Emperor's sons.

Her suspicions over the attempt on Tenyou’s life having settled on the third prince, Kougai, Rangetsu’s investigations reveal some surprising truths about her suspect. A violent bit of sport leads to another very intense competition, where it’s all fun and games until somebody loses something valuable to them…

If you want a book with a bit of nuance to it, you could do much worse than this delightful little series as it continues to mix courtly intrigue with simmering passions and all sorts of deliciousness.

The biggest through line in this volume is the third prince and his plotting and motivations. We see this initially during the sporting tournament, where he is a little obvious in his intention but the ‘why’ remains unclear (and there’s a bizarre throwaway joke about character merchandise).

The tournament is fun and its presentation and results are stellar in that just enough of it is on the page and it doesn’t simply give up the easy win for our heroes. It’s an easy trap to fall into, having your protagonists succeed without effort, but the author deftly settles on something that works far better.

This all turns out to have a more far-reaching effect on things and when Rangetsu starts to dig a little deeper she finds out the prince’s true nature and Kougai is not the obvious suspect he first seemed.

There’s a nice declaration of public versus private personas here and how Kougai’s actual goal is to see Tenyou throw himself properly into something. Which ends up with Rangetsu as the prize in a combination board game plus archery competition plus drinking game.

This section makes the book, honestly, as it not only shows that the sporting event had deeper repercussions than expected, but really lets the two princes act as proper family for a change and cut loose during a silly bit of sport between two people who normally would be at one another with their hackles up.

Everything in this series tends to be wound so tight that the feeling of release here is palpable. There’s some great art that expresses the familial aspect to a wonderful degree. Which is why the final twist of the knife is so shocking and shows that nobody here should be taken at face value.

Even the softening of Rangetsu is addressed, as she realizes that she’s falling for Tenyou in a very bad way. It’s ironic that her losing part of her edge and falling in love would make her even more dangerous (and endangered) because of how hated beast folk who gain status in the court have been.

Of course, there is a sharp reminder of her place in society at the end, courtesy of Tenyou’s miserable sister, that causes her to attempt to distance herself from Tenyou. It will probably go as well as we expect, but at least she remembers that this isn’t a safe space.

5 stars - I love this series so much and the baseline atmosphere of scheming and danger that just oozes off its pages. It feels like an epic story through and through; a pure delight of a read.

In this 4th installment of The King’s Beast, the plot thickens around the mysterious third prince and Rangetsu grapples with her growing feelings for Prince Tenyou. I found this volume to be more interesting than the previous two as the poorly conceived, budding romance mostly takes a backseat. The plot of this volume revolves more around the third prince, Kougai, and Rangetsu trying to figure out the kind of man that he is. What is Kougai plotting and what role may he have taken in her brother’s untimely death?

Rangetsu’s character throughout this story has waffled a bit. Sometimes she’s calculating and clever, but other times she seems a bit helpless. I wish there was more consistency to her character, and her interest in Tenyou just seems so forced and frankly, unbelievable. Given the world-building, I just can’t imagine what she sees in someone like him. I personally don’t ship these two characters, and I think that the story overall would be greatly improved had this story not been a romance.

That being said I’m still really interested in the more mysterious aspects of the story. I want to know which one of these princes is destined for the throne, which one killed Rangestu’s brother, and whether or not Tenyou will betray her. These plot points and the lovely art style are what keep me entertained and reading.

This is definitely my favorite volume so far! These volumes go by so fast!

Nothing major happens in this volume, but I still found it amusing. I enjoyed learning more about some of the characters! It might be considered a filler volume, but I thought it was well-done! I think it did a great job setting up for more important events in future volumes.

There was a new character introduced that I can't stand already, but it's not enough to affect my overall opinion of the series! I think these upcoming volumes are going to get pretty interesting!

Better than previous volumes. The artwork is seriously beautiful. Some of the detail in Rangetsu’s eyelashes, oh wow! – 5 points for the incest joke. Mangakas, no one wants that. Thank you.

I really need the prince to find out that Rangetsu is a woman. I'm still enjoying the story; I'm just wondering how long does the author plan on drawing this out.

Admittedly, this volume was actually really interesting, and I enjoyed reading it. Specifically, the way we are learning about the characters, the introduction of princess Ririn.

The emotions between Rangetsu and Prince Tenyou are building! Eep.

I'm not sure if I will pick up any further volumes!

Rangetsu believes that it is none other than the third prince, Kougai, who had intentions of humiliating Tenyou. When a competition between the brothers turns brutal and Rangetsu gets hit more than necessary, Tenyou is bitter. Rangetsu is determined on finding the truth, and Kougai is determined to bring his brother down. A wager between the two becomes a battle of stakes, with Rangetsu as the prize.

*Thinks about this series🤔
*organizes thoughts🤗
I am repeating myself with every book review of these volumes, but they are absolutely intriguing. Immersive, atmospheric, and filled with action, this series is conducive to making you fall in love with manga. I find myself introducing this to every reader I meet. Tenyou is the sweetest love interest. So kind and caring, and I love how he cares for Rangetsu. Although the two have a very strong relationship and aren't lovers yet (judging by the covers in the other books. . . that intimidates me, especially book six-I mean what's going on THERE🤔?)

This is a true story. I got hacked by going on an illegal website trying to find out when Tenyou realizes Rangetsu's really a woman. It was worth it! I got early access to some interesting scenes with tension. . . but well, I got a virus on my computer. It was worth it for this series although I never actually got to see the scene🥲.

Rangetsu is an Ajin who owns her rights. She is fierce and brave. I love how Rangetsu is out-spoken but also has the right amount of self-control. Rangetsu's struggle with trusting Tenyou never felt ridiculous or repetitive. It made sense and was done in a relatable and reasonable way. The third prince is mysterious, and his character was intriguing, setting aside the confusion I have about looking at book six's cover?

I love the aesthetic of the art, the flowers, and beautiful costume design, buildings and scenery. The introduction of Kougai's sister, I enjoyed seeing their back-and-forth arguing AKA sibling relationship. Kougai's sister herself is just . . . the way she treated Rangetsu? Nah, I don't like her.

During stressful times, even if I didn't book two, I would flip ahead through these books because they bring me happiness! I hope I receive book five, six, seven, and eight from the library soon.

This was so good! This volume dives deep into the character of Kougai – the third prince – as Rangetsu confronts him with her suspicions of his intent towards Tenyou. After realising he doesn’t pose much of a threat, Rangetsu tries to back off; only to be pulled back in by Kougai’s schemes.

Honestly, my favourite plot in the series has to be the rivalry between Kougai and Tenyou. Kougai's playful – and somewhat childish – determination to vie for his younger brother's attention is charming and adds a fun layer to the story. I love a good blossoming bromance!

Boku’s relationship with his master adds another fascinating dimension to the story that definitely left me craving for more.

And Rangetsu’s further character development is equally compelling. She finds herself falling for Tenyou but an intervention from his younger (and utterly horrible) sister, RinRin, serves as a stark reminder of her societal position – which makes her attempt to distance herself from Tenyou.

I can't wait to see how this tension evolves. Will Rangetsu manage to stay distant, or will her feelings prevail? Exciting times ahead!

Thank you, VIZ Media, Shojo Beat NetGalley, for allowing me to read this volume all in exchange for my honest thoughts! I am continuing this series!

So I have had the opportunity to read each volume of this series, and I think it is a great series. It switches between getting the backstory of the princes and their beasts and the goal to be emperor. I only dislike that we are going further away from Rangetsu’s revenge and justice for her brother, as it hasn't been mentioned in a little, but I do know we are getting to that as it is all connected.
Also, I am so happy they shut down that weird and uncomfy statement the half-sister said because I CANNOT DO ANOTHER INCEST TROPE; high school me is still scarred from Vampire Knight.

I still do not know who I like Rangetsu with, but I think the Prince is good!

*I received an eARC via NetGalley in exchange for an honest review.

4/5

Vol 4 of the Kings Beast by Rei Toma is another excellent addition to the series. Im really Glad we’re getting to learn more about the world, the characters, but also getting some action scenes in.

It’s really getting juicy now. Things are really starting to build up and I'm so excited. I hope all this world building is worth it. But I’m pretty sure it will be.

I love Rangetsu. They’re such a fun but awesome character. I need to see more of their badass-ery please!

The art continues to be amazing. The action scenes are still kind of confusing, but I think I’m just dumb. The world building in character development is great. I really can’t wait for more.

It's great to see Taihaku look out for Rangetsu even though his initial reason for keeping her secret was solely out of fear. Development!

Also, seeing the third prince Kougai do a whole 180 personality switch once he realizes he has an audience... that was funny. I'd love to see more of him and his beast servant, they seem to have a fun dynamic.

We also met the young princess! Who sparks a bit of envy? In Rangetsu? At least in terms of femininity, Rangetsu seems a little wistful of her appearance. As well later on, Rangetsu begins to realize she may have some feelings for a certain someone.

In crescendo de sentiments entre la Rangetsu i el quart príncep a la vegada que la rivalitat amb el tercer príncep, que amaga la seva personalitat real, es va fent cada cop més palesa... primer partidillo com a prova per saber qui serà el proper emperador i després disputa entre germans per la Rangetsu. Els protes dissimulen fatal els seus sentiments: l'un dient-li cute tot el dia a l'ajin i l'altra fotent unes cares d'enamorada que fan sospitar a tot cristo... A més, apareix el personatge de la Ririn, germana petita dels prínceps i que fa una mala espina increïble. Per fi el ritme i la trama es fan més trepidants! :)

Rangetsu gets up close and personal with the 3rd prince, Kougai (the one who almost caught her in the bath) and finds out that he's not all he seems to be. Personally, I can't tell if I love him or hate him.

Meanwhile Rangetsu gets a stark reminder that she's an Ajin, lesser than a human, and gets confused as to whether her feelings are respect, love, or straight up irreverent treason. And I've never wanted to slap a bitch more.

The third Prince finds out that Rangetsu is the key to properly compete against Tenyou and requests him as often as he can,to Tenyou's chagrin.

The third Prince challenges Prince Tenyou for ownership of Rangetsu,and Tenyou uses his wit to not only keep Rangetsu but also acquire a valuable asset from the other man.

Princess Ririn has a birthday party and Rangetsu is brutally reminded of her place in the world and that whatever feelings she is developing for Tenyou will never be fulfilled.

Rangetsu continues to draw the interest of the other princes and their beast servants, though it seems this new princess doesn't have a high opinion of Ajin. Tenyou shows more than a bit of cleverness as he fights for Rangetsu in his own way - which does not seem to be helping her growing confusion and changing emotions. Likely none of this is helped by Tenyou's increasing insistence on calling Rangetsu cute, no matter how accurate the assessment may be at times.

Kogai, fratello maggiore di Tenyo, altro non vuole che provocare una qualsiasi reazione nel fratello, e per farlo si serve di Rangetsu. Ma Tenyo non casca nella trappola e riesce, grazie ad un gioco da lui reinventato, a dimostrargli di che pasta è fatto. Nel frattempo, Rangetsu si rende conto di aver scordato di essere solo un "servo bestia" grazie all'alterigia della principessa, che le fa notare appunto qual è il suo posto...

This was so good! Honestly, I love how this romance is portrayed; it doesn’t ignore the main issues in the story – societal discrimination and inequality – in order to provide a happy ending for the characters. It makes it even more lovable.

This volume also explores some new characters and there are some really significant realisations that I’m incredibly excited about.

Exciting times ahead! I can't wait to see how this tension will evolve 🤭

Third Prince Kougai is very interesting. I love his two personas. He is quite childish in private but he pretends to be cold in public. He wants to know what makes everyone tick and forces his younger brother to step up by trying to take Rangetsu from him. The competition between Kougai and Tenyou was clever. Tenyou created a fun challenge with serious consequences.

In volume 4 Rangetsu suspects that the third prince Kougai was the one who tried to poison the tea at the last banquet. The third prince challenges prince Tenyou to a competition requesting that if Tenyou lost he would give up his beast servant, Rangestu. We also get to meet the Princess, Ririn. I am not a fan of her but we’ll see what she makes of herself.

Este tomo es mi favorito hasta la fecha. Me ha encantado la aparición del tercer príncipe Kôgai además que es el nuevo Crush supremo y lo shipeo con su bestia aunque no me den el ship me da igual. Me ha encantado cómo Tenyô ha sacado las garras y ha luchado por Rangetsu. Además de que Rangetsu cada vez es más consciente de lo que siente por el príncipe.
