I’m afraid I don’t! I’ll publish this to see if anyone else might know of it.
Allo. (first sorry for my English) I searched for a long time a clip who use the toast troop. It's a video clip from a song jpop with a real person (I think it's a boy dress like a Japanese schoolgirl). She is late for school with bread in her mouth. (Also have a scene in a subway and a cool choreography). It's old (between 2005 and 2010) and I think the name is zakura. But with all this information, I don't find it. Maybe you know it? I hope so. Have a nice day.
Has anybody made any Danganronpa pics with this trope of being late to school and having toast in their mouth?
From the Sega online PC game Phantasy Star Online 2. In the game players can equip fashion accessories on their characters like bags, hats, earrings, and even food items like the toast in mouth. Mix it with the school uniform outfits and BAM! I’m gonna be late for school!
