Your Character Settings Don't Make Sense

Shiina Miyu from the Data Department of the Space-Time Administration accidentally leaked the source database, allowing some contained source data to flow into other worlds. To make up for his mistake, he had no choice but to personally visit the minor worlds and retrieve that source data.

In the minor worlds where the source data had flowed:

The bandage-wearing man who had jumped into the water was rescued by [Dazai, Son of Light].

Bandage-Wearing Man: This is terrifying. It's even scarier than the dark little dwarf growing to six foot three.

The agency president picked up [Ranpo the Canary] on the way to the detective agency.

Agency President: How about coming back to the detective agency with me?

A first-year student who had just reunited with his shady teacher stared at [The Cultured Clan Head Gojo], who looked just like their teacher, and fell into an infinite void.

First-Year: It's the exact same face, but somehow the other guy is way more handsome than our teacher.

When a second-year student was exorcising a curse, [Yuta the Curse User] suddenly showed up and stole the kill. The student called their classmate overseas.

Second-Year: Yuta, we ran into your twin brother!

At a gem exhibition, the white-clad phantom thief came face-to-face with [Phantom Thief Ran].

Kuroba: Great Detective, you probably won't believe this, but the gem I just stole was stolen by your girlfriend.

At a murder scene, a certain elementary school student and a blond, dark-skinned waiter stared at [Detective Kurosawa] in utter shock.

The two of them: This must be an illusion, or I'm still dreaming and haven't woken up.

After learning these were alternate-universe counterparts, everyone said: How can this character be so wildly different!

*These aren't secret identities. The cards are source data from parallel worlds, and they are genuine counterparts from parallel worlds.

Theme: Different choices lead to different lives.
