About
Lifespan: 100 Days (3 Months)
Bucky is introduced as the Chicken Devil.
The purpose of Bucky was to be killed and eaten by the fellow Students in the Classroom in order to teach them how precious Life is (this was conducted by their Class Teacher who is known as Mr. Tanaka)
As the Days passed, the Students gained a sense of affection for Bucky and didn't feel the need to kill him, knowing this... Mr. Tanaka was grateful that this "experiment" was a success.
~!Chapter 98 (Bird and War) — Bucky is 'accidentally' killed by Asa Mitaka when the Class President tripped her on behalf of Justice Devil's Advice in order to reach a "Happy Ending" with Mr. Tanaka!~
