What's the term for the bullied kid who delivers bread and sandwiches to the bullies?

Question

I think it's a designated term for this kind of character. Usually they use their own money to purchase foods during lunch in a school setting for the bullies.

Answer 1

Bread Shuttles. Korean. Not Japanese.

빵셔틀

[ppang-syeoteul] Term literally meaning ‘bread shuttle.’ Usually used at school, where one student is picked on and/or bullied to do the errands for people who are in a stronger position than they are.

There's an example of this in Sumire 16-sai!!, chapter 1:

The word is パシリ (translates to "gofer" in English):

Person who is made to do things or go get things for someone else; person who runs errands; gofer​ (see also 使いっ走り)
