You are looking at a meat bun of virtual idol Hatsune Miku. This isn't the horror part. The horror has not yet started. Oh no. This gets worse—much worse.
The above photo (taken by Otalab) shows a fresh Hatsune Miku meat bun. But what happens when the Miku buns are left in their Family Mart bun locker all day? Or when people start eating them? Or playing with their food? Or worse? Horrors, that's what. *shudder
In case you missed it, here is Japan playing with the Dragon Quest Slime meat bun.
