I Cosplayed as Can Canzi and Transmigrated [Demon Slayer Crossover]

With no friends in the cosplay community, I cosplayed a female version of Tragic. So I wouldn't look too lonely, I lured my ten-year-old nephew into cosplaying as young Tragic with a rare, out-of-print doll, and took him to a convention with me.

Then we happily walked hand in hand into the real Infinity Castle.

Me: How did this happen?!

My nephew: Are you an idiot?

Question: What is the life story of a legendary figure usually like?

Me: Thanks for the question. I'm at the Ability Special Affairs Division, just got back from the Infinity Castle, and single-handedly defeated the Twelve Kizuki and Muzan. I currently serve as director of the Ability Special Affairs Division.

Oh, right, I also have a nephew. When he grows up, he'll become a top-class dangerous ability user under the division's surveillance...

Wait, I think I left my nephew in the Infinity Castle!

* The heroine is Shenyue, who has not yet become director of the Special Affairs Division; her young nephew is Ayatsuji.

* A happy family.
