Yukio Arakawa (Raven Warrior)
Voiced by: Showtaro Morikubo
Achilles in His Tent: After he completely loses his confidence due to losing his powers as an Animal Warrior during his fight with Naoi because of his guilt of kicking Makoto out of Team Raven after Itsuki returned in episode ???, he spends his time moping in his room. Eventually he changes his mind with a little persuasion from his team.
Heroic BSOD: Yukio finds himself in a funk throughout the first half of the Ayato Naoi arc after losing his powers as an Animal Warrior because of his grief of kicking Makoto out of Team Raven after Itsuki returned after Mal's demise, fearful of seeing him again.
10-Minute Retirement: In episode ???, due to losing his powers as the Raven Warrior during his fight against Ayato Naoi due to his guilt of kicking Makoto out of Team Raven in the previous episode. He bounces right back in order to help a student who, in a twist on the usual outcome of this trope, turns out to be Nui in disguise, who promptly defeats Ryuko and tears up Senketsu.

And Then John Was a Zombie: Trent was turned into a monster and controlled by the (former) Elite Sorcerer Ciel Phantomhive because of his jealousy of Takeo Fujimoto and Kasumi Kuroda's growing friendship. He gets better after being purified by Yukio with his newly-awakened Animal Warrior powers.
Paint It Black: His armor, leggings and armbands from his armor undergarment from his Lemur form turn much darker after Mal takes over Itsuki after drinking all of Van Kleiss' potion and turns into the Lemur Warrior.
Reincarnation: He has become this of the previous Lemur Warrior, Kitsu Nesaru's alternate personality, Vlad after Itsuki drank Van Kleiss' potion that was made with the pieces of Vlad's soul and some of his blood.
And Then John Was a Zombie: Kanami was turned into a monster and controlled by the Elite Sorcerer Van Kleiss because of her doubt of Mike acting weird. She gets better after being purified by Itsuki with his newly-awakened Animal Warrior powers.
Foil: To his successor, Yukio Arakawa. Crimson is kind, friendly, calm and active, but has a ruthless vengeful side towards his enemies, while Yukio is cynical, snarky, stoic and lazy, but has a soft and active side.
Killed Off for Real: When Crimson mercifully stabs Vlad (Kitsu) on the stomach, Vlad is destroyed, but Kitsu spits some shards of his soul, which Mukuro Rokudo stole and gave them to Van Kleiss to create the potion that will completely make Mal take over Itsuki.
