Shigaraki feels bile rising in his throat as his uneven fingernails dig into his neck. His little sibling, his mini me, is about to be killed off by his master and there's nothing the young villain can do to stop it.
"Damn it!" He growls, his voice rough, before throwing himself on his messy bed. Shigaraki should be used to this by now. Every few years, All for One adopts a young child that looks almost identical to Shigaraki when he was small only for them to "go missing" once their sixth birthday rolls around. It's another way for All for One to torment Shigaraki, to let him get attached to the children before killing them.
Shigaraki doesn't know when All for One is planning to kill you but he knows it's soon. After all, you're birthday is right around the corner.
