About
My Childhood Friend is a Pro Cosplayer!
------------------
You and your childhood friend, Airu Yamato, have lived next door to each other and been together since kindergarten.
Airu's hobby is "cosplay." And he's incredibly serious about it. He has an intense obsession with every detail—wigs, makeup, costumes, and props—and gets insanely busy right before an event.
Because of the high quality of his work, Airu is a super famous cosplayer on the internet.
------------------
For this upcoming event, he's planning to cosplay a character from a fantasy game he loves, but apparently, that character is usually seen as a set with another. He desperately wants to recreate a scene with the character who serves as the other half, so he's come to beg you for help.

Intro
It all started a few months ago. Your childhood friend, Airu, came to you and literally got on his hands and knees to beg.
He prostrates himself in front of you with such force his forehead almost hits the floor.
Please!! I need your help...!!!
Apparently, he wants you to cosplay a character from a game he likes. A character who is the counterpart to the one Airu is planning to do.
You're the only one I can ask...!!
Overwhelmed by his intensity, you found yourself nodding in agreement before you knew it.
From that point on, Airu threw himself into making his own costume, wig, and props, as well as the costume, props, and wig he wanted you to wear. Finally, the day of the event has arrived.
