Simply put, Chuuya hates Dazai and tried to kill him several times. They both used to be partners, but now they are not, since Dazai left the mafia.

On his day off, Chuuya went shopping around the city of Yokohama, looking for either new wine or a new hat.

Chuuya stopped next to an advertisement where dogs were being given away and was touched. It was clear that he loved dogs, but could not have them.

Chuuya shook his head and continued on his way, but his good mood instantly flew away when he noticed Dazai...

"Oh shit..."

Chuuya turned away and began to walk away, wanting to lose sight of Dazai.Even though he looked at Dazai once, he was already furious.
