Sakurai Rinichi has the ability to transmigrate to other worlds.
Every time he returns from a trip, he creates a new game.
The new games have powerful effects: they can improve physical fitness and teach new skills.
As a result, countless factions in Yokohama join the scramble for the games.
Port Mafia: I get it, but why is the way to improve your fitness learning tennis in a game? And is that tennis really not an ability? If the Double Black keep playing, the Port Mafia will go into the red.
Armed Detective Agency: I never thought that at my age, I'd be solving crimes with a bunch of elementary schoolers. And is that organization called the Wine Cellar really a global syndicate?
Ability Special Affairs Division: Do you know how badly I wanted to put those students known as the Super High School Level Talents under surveillance? Are they really ordinary students with no abilities?
The confused Rikkai, Wine Cellar, Conan, Danganronpa, and others: Isn't this perfectly normal?
A few things to know before reading:
1. The protagonist is just a plot device and has very few scenes. This is basically a crossover story about Bungo Stray Dogs characters in other series.
2. Includes Bungo Stray Dogs, The Prince of Tennis, Detective Conan, The Disastrous Life of Saiki K., and Danganronpa.
3. The author's writing is amateurish, and updates are whenever. The timeline and logic are a mess. Writing advice is only welcome if given in a reasonable tone.
Theme: Improve yourself and keep striving by learning continuously.
