Shishi- A term for a kodo who is dead or dead-adjacent, such as being undead or who appears to be dead.
This is the explicitly kodo version of shitai, a term for characters that look to be any age who are dead or dead-looking.
"Shishi" is another word for corpse in Japanese. I thought it would work as a cutsier version of shitai, and the sound repetition reminds me of Lily from Zombieland Saga, who is a zombie loli.
