Shizuma Hoshigaki

Shizuma is a deceptively older looking individual despite still being only in his teen years. He is a tall young man with pointed teeth, shoulder-length wavy black hair which he usually lets face all over the right side of his face, and light blue eyes. He wears a red, sleeveless, pinstriped turtleneck shirt along with matching arm-warmers and black pants. He also carries a sword strapped to his waist. Seemingly when emotionally worked up enough, he produces two sets of gill-like features under his eyes and markings around the outer corners of his eyes. After declaring war he dons a sleeveless black jinbaori war coat with tan lining and grey hemming, worn as a surcoat in the traditional style. Across his chest is a long thin scar he got from Kagura after taking a blow that Kagura intended for a student. While improperly merged with Samehada and the sword's dominance turning him feral, Shizuma grew larger and more defined in his musculature. His right arm also turned grey and fin-like with claws for nails. His face grew out to form a snout with pronounced fangs and wide mouth and his eyes became fish-like.

Shizuma was once a teacher at the Kirigakure Academy. During a sparring match between Kagura Karatachi and another student, Kagura quickly went into a frenzy, nearly killing the student. Shizuma stepped in to take the blow, saving the student. While all the others quickly rejected Kagura, viewing him as a monster like his grandfather, the Fourth Mizukage, Shizuma secretly applauded Kagura's bloodthirsty side, insisting that he was as he should be for the coming age. Since then, Shizuma always kept watch over Kagura, protecting him from harm. At some point, Shizuma got into a relationship with Buntan Kurosuki.
