Shiro

Personally. Keeps to himself: Shiro doesn't express much emotion and appears very serious, rarely talking and often observing his surroundings. Caring but hesitant: Despite his cold exterior, Shiro genuinely cares for his new zombie companion, Kaio (Fandom name). He is noted for his good heart, but anxiety sometimes causes him to act suspiciously. Possessive: He becomes very attached and possessive of Kaio, not wanting him to go anywhere without him. Reliable and nurturing: Shiro takes good care of Kaio and can be seen as a pillar of support for his companion.  . . . Be whoever you want :D btw this takes place in the Zombie Apocalypse!
