Tsuyo (YI Arc)

"He was a apparently the Greatest Gladiator and Warrior in Soul Society a long time ago, his rival being the Prince of the nation, but the Prince's loyal advisors felt threatened by the Gladiator's potential victory and through amassing fake crimes had him beheaded. Or so the legend goes."

- Kenpachi Zaraki, explaining the common legend within the 11th Division.

Tsuyo is a member of the Eight Yōkai Emperors and their great warrior in their quest to lead both the living and spirit worlds into Chaos, in his past life he was a member of 11th Division but was far more famously known as a Gladiator within Soul Society that rivaled the Prince of the land, however the advisors of the Prince saw his potential victory over the Prince as a threat without knowing the exact extent of their relationship and so had the Gladiator executed on false crimes despite the Prince defending him.

Physical Appearance
While he was in Yomi, Tsuyo wore dark red robes with a hood over his head and eyes that glowed with a orange light. Tsuyo is also one of the shorter Yōkai introduced, being tied with Eiyū for the shortest.

In his true Yōkai form, Tsuyo is a red-skinned Yōkai with three blade-like horns that protrude from the sides of his head and a decidedly alien-looking mask-like face. He wears a short crimson vest decorated with three yellow gems with a high collar on. Like Eiyū, he also has a large Yōkai emblem with an orange outline on the right side of his chest. He keeps his Yōkai Jueru on his right wrist.

While in human form, Tsuyo takes the shape of a young, dark skinned teenager with green eyes and three different-styled gold rings on his left hand. His hair is shaped as curls that resemble tentacles, dark brown in colour, short and his bangs cover his right eye.

Curious on where Venku had disappeared to, he appears disguised as a student in Karakura High School, thus wearing the standard red-lined uniform, blue pants and brown shoes. Despite his small size and lean frame in human form, Tsuyo is also fairly muscular and well-built.

After his true nature was revealed, Tsuyo abandoned his school uniform in favor of a red long sleeved shirt with a high upturned collar, white pants, and added a golden, rectangle necklace to his accessories. When Tsuyo first returned to Karakura Town, he wore a black cloak over his new attire.

During his previous life as a Soul Reaper, Tsuyo wore a golden necklace and red gladiator armor that covered his midriff, left shoulder and chest.
