Superpower Stand-In Fiction

(Featuring the upcoming novel, "I Opened a Cat Cafe at Tokyo Jujutsu High"! The full manuscript is already complete~)

Fake [body-double fiction]: Summoning an alternate-world counterpart to possess me and help me fight monsters.

Real [body-double fiction]: Traveling to another world to save my useless alternate-world counterparts.

Counterpart A: SOS! I'm getting engaged to the young master of the Demon Slayer Corps. Your guy's about to grow a pair of horns!

Counterpart B: 9999! My idiot little brother called me a monkey and is chasing me with a sword. What is wrong with him?

Counterpart C: That garbage distillery is doomed. Wait, the distillery's boss is actually me?!

Taozi: Other than smiling through it, what can I do? At least I've got friends to run dungeons with.

Dungeon buddy, young Shuji: After all these worlds, I've come to think humans are so interesting. I LOVE humans! I like humans best! Ugly humans, beautiful humans, desperate humans, dazzling humans. Let me see more!

Taozi: The grass is growing! You're acting so out of character you've wandered into another show! The gorilla from Heiwajima is coming over carrying a vending machine!

Dungeon buddy, teenage Oda Sakunosuke: Shuji is so cute.

Taozi: Don't encourage him, hey!

Special Abilities Division File:

Kubo Tao, super-A-class ability user. Her ability varies, and she may possess multiple abilities.

Three family members: younger brother Kubo Shuji, ability status unknown. Older brother Oda Sakunosuke (?), ability status unknown. Recommendation: Keep under close observation.

Kubo Tao: Stop watching me! I'm actually just an ordinary person. I'm only a bit stronger than most.

Patient No. 1: Ordinary person, same here. I'm just a regular high school student who loves coffee jelly.

Patient No. 2: Ordinary person, likewise. I'm just a mere demon.

Patient No. 3: Ordinary person, me too. I just like reading [books], and taking a peek at my parallel world's past and future now and then.

Patient No. 2: By the way, No. 3, when are you going to hell? I'm really short on people here.

Patient No. 3: I'm honored by your kind offer. I'll make sure to live to a ripe old age :)

Taozi: No. 3, you're acting out of character too, just like my Shuji...

Another World, Geto Tao: Stop chatting! My unlucky little brother has made it to my doorstep! Requesting a body double! Aaaaaah, help, help, help, help!

Kubo Tao: Coming, coming! Special Ability: [Body-Double Fiction]!

Kubo Tao, age 12, amnesiac: I have just one question. Isn't my name kind of weird?

Geto Tao, not Summer Orange: Just smile.

1. The heroine has an overpowered cheat ability. The counterparts have different personalities due to their experiences. The counterparts have no romantic storylines.

2. Don't scrutinize the timeline or plot. It's a big mash-up, after all.

3. The characters belong to their original works. Any out-of-character behavior is on me.

P.S. Is it weird that both the platonic relationships and the couples are all Dazai-based creatures? (The pairing is pretty obvious.)

Theme: Healing others can also heal yourself.
