I’m Not the Heroine!

I am Irisviel from the Holy Grail War;

I am Shino Asada from Sword Art Online;

I am Nezuko Kamado from Demon Slayer...

But do you think I'm the heroine?

...No, I'm the hero.

It all starts with a game...

P.S. This is the fourth version of the blurb. I really don't want to change it again... [tears streaming]
