[Crossover] After Cosplaying the Cult Leader, My Best Friend and I Ended Up in Yokohama

I'm just an ordinary college student.

After cosplaying as Doma, I transmigrated while on my way to an anime convention with my best friend...

Doma: "Lord Akaza, have you noticed that everyone around us is speaking Japanese..."

Akaza: "Akaza? Doma, you're taking this role too seriously. Call me by my name... Wait, I'm..."

Seeing several towering buildings with the words "Port Mafia" on them outside the bus, the cult leader couldn't help happily clapping his little hands~

Doma: "Woohoo~ We're doomed."

Question: What would you do if you transmigrated as Doma?

Answer: Thanks for asking. I'm in Yokohama, just got off the bus, my best friend turned into Upper Three, and I don't have a cent in my pocket.

Ah~ Guess who we saw on the way?

Oh~ Dear Lord Akaza~ Isn't that the Flame Hashira you can't stop thinking about? Wait, why is he coming over with his sword out??? Hold on! Let us explain!

Setup:

1. There are two protagonists. They aren't demons because they aren't wearing colored contacts, but their regenerative abilities are similar to those of the original characters.

2. Doma still has his Mary Sue eyes. Since he's a cosplayer, he has emotions, but they're pretty muted, and all his abilities are geared toward causing trouble.

3. Characterization may be out of character.

4. The present-day Demon Slayer Corps may appear.

5. The pairing is probably cosplayer Doma x cosplayer Akaza.

Theme: Trouble may arrive late, but it never misses its cue
