However, Fifteen is imprisoned for three years after being severely injured by his enemy.

After Fifteen is released from prison, he decides to live a normal life with Ah Sai. Fire, wanting to eliminate a potential threat, orders Millennium B to kill Fifteen, but coincidentally discovers that Ah Sai is now with him, which drives him to irrationality.
