My brother, who's 10 years older than me, quit his job last year and has been staying cooped up in his room ever since. But one day, he suddenly jumped out of his room yelling about how he's gonna be a manga artist. That surprised me, but I was really happy to hear it since I like it when my big bro is excited. I've gotta support him in any way I can. ...And that's why I'm currently modeling for him as a reference. What sort of costume is this...? I don't really get it, but do your best, big bro!!
