Yoite is a 16-year-old ninja. He uses the Iga’s kinjutsushō “Kira”. This technique shoots the user’s ki into the target’s body and controls it from the inside out, causing the target’s bones to break or their body to completely explode. The cost of using this technique is the loss of the user’s life force, gradually losing their five senses and eventually dying.
Yoite was born intersex, named Sora, although Yoite never considered it to be his name. His mother died in childbirth. His father considered him a death god for that reason. He was confined to the basement and his half-brother Tsukasa Kōdō was forbidden to approach him. When Yoite turned fourteen, his family decided to kill him, slashing his throat and unsuccessfully attempting to force Tsukasa to do the same. It doesn’t work and he survives.
Yoite lives out the remainder of his life with Thobari, Hanabusa, and Gau. When he dies, his body evaporates into sparkling lights.
