System 234: Host, you only have four tasks left before you can retire!
Changze Si: Doing them one by one is such a hassle. Why not do them all at once?
And so...
Changze Si became an excellent master of time management, shuttling between four different little worlds.
In the morning, he was the kind soul who took in a homeless Ranpo kitty.
At noon, he was the spiritual mentor of Jono Saigiku, who was still an executive in a criminal organization.
In the evening, he was the young master of the Port Mafia, standing in the way of Mori Ogai's rise to power.
At midnight, he was a tough guy from Suribachi Street who taught the "King of the Sheep" how to behave.
One day, Changze Si finally completed all his tasks, only to discover that he couldn't leave! And the little worlds had somehow merged, without playing fair at all?!
Changze Si: Yikes, I went too far.
Later...
When he ran into Ranpo kitty: Hey, hey, hey, don't look at me like I've abandoned you.
When he ran into Jono Saigiku: How come you're still so nasty after joining the Hunting Dogs, huh?!
When he ran into Mori Ogai: Hey, hey, hey, does that look on your face mean you want to kill me again?
When he ran into Nakahara Chuya: Um, I know I beat you up before, but could you please not beat me up?
Changze Si even tried to make excuses: Well, actually, all those things I did before were the work of my evil soul. They had nothing to do with me~
Premise: Love and peace.
