Ye Yu, the most arrogant delivery boy in the world.
The conflict broke out - the system forced him to deliver supper to the villain who had just killed someone. He had to smile and get a five-star review while the knife was still dripping with blood. He couldn't last a whole day in this bad class!
Ability hints - an incubator can contain Soul Society and Hueco Mundo, and a menu can predict all life and death. He looks like a walking meal ticket, but in fact he is a walking disaster.
A cool preview - when all the anime protagonists begged him not to give extra meals to the villains, Ye Yu innocently spread his hands and said, "I'm just a box lunch deliverer. What does the destruction of the world have to do with me?" Sweet or salty? It's extra money to send it to the underworld.
