* MightMakesRight: His childhood opinion of worth is based entirely on strength. He bullies Kyuta remorselessly for being weak, but warms up to him ''immediately'' after [[DefeatMeansFriendship the human defeats him]].

* DelinquentHair: As an adult, he sports a pomp hairstyle.

* HasTwoDaddies: A very unique variation. Kyuta was taken care of by his mother until she died and he ran away as a result. He's later adopted by Kumatetsu and then co-raised by him, Tatara, and Hyakushūbō. [[spoiler:And his biological father is also alive and Kyuta goes to live with him in the end]].

* BerserkButton:
** He doesn't like it when he's being compared to his rival, Iozen. When Kyuta said Kumatetsu will never be as good as him, it almost sent Kumatetsu into a flying rage as he chased Kyuta around the house.
** Kyuta questioning or disobeying him as an apprentice. Played somewhat for laughs at first, as an awkward, unpolished teacher bickering with his unruly pupil, but takes a serious turn when [[spoiler: he discovers Kyuta has been spending time in the human world and considering returning to school instead of pursuing swordsmanship]].

-->'''Voiced by:''' Kōji Yakusho (Japanese), Creator/JohnSwasey (English)[[note]]'''Other languages:''' Dafnis Fernández (Latin American Spanish)[[/note]]

* {{Bishonen}}: He has a slender frame and delicate features.

** Ichirohiko is a dignified and popular {{Bishonen}}, but Kyuta looks like a shaggy, shabby ruffian, something that gets pointed out by humans.

* NiceHat: He wears a hat that is shaped to look like a boar.

* LivingEmotionalCrutch: {{Implied}}. [[spoiler:The main reason Kumatetsu won the title of Grandmaster was because Kyuta/Ren's "cheering" reignited his spirit.]]

* YouGottaHaveBlueHair: Ichirōhiko has blue hair.

* ChildrenRaiseYou: Kyuta is the one who takes care of all the housework for Kumatetsu. It's also noted that taking in Kyuta resulted in such an improvement of Kumatetsu's character that one has to wonder which one of them is really the teacher.

* ReformedBully: He first starts off as a bully to Kyuta/Ren, but after the human TookALevelInBadass, Jiromaru became his friend. And even before that he had an earnest respect for his father and brother.

* EverythingsBetterWithMonkeys: A monkey beast who provides some comic relief.

* BadassBeard: He has what qualifies as a beard and it is awesome looking.

* ParentalSubstitute: To Kyuta, before Kumatetsu takes over. He rescues Kyuta from the wolves and promises to loom after him, despite most beasts' fear and distaste for humans, and then encourages Kumatetsu to do the right thing and bring the boy home. When Kyuta begins his apprenticeship, it is Hyakushubo who supports and soends time with Kyuta, while encouraging the stubborn Kumatetsu to do the same.
