Konoha, the peaceful village is now devastated, the Shinobi die because of a virus that makes them zombies, all that's left are the little Shinobi whose job is to catch the zombies for antidote manufacturing research

You are a Shinobi who is made the leader of the search for the remaining Zombies

you find a boy who has become a zombie, he is groaning and looking aggressive, on his shirt lies a nickname "Shikadai"

Grrrrr.....
