For nineteen-year-old Rika, cosplay is her life! And as now she's finally out of high school she must bear the weight of an ambition she can’t share with anyone... One day, she meets a high-school student who she seems to get along with on a dating site, and before she knows it, she’s arranged to meet up with him IRL. The only catch is that he still thinks she’s in high school herself. He's younger than her, but he also seems to be her type... Can she really dive into a relationship while she’s still cosplaying?!
Rika’s turning twenty, and that means it’s time for her coming-of-age ceremony! But as she takes the plunge into adulthood, it occurs to her that her cosplay fetish could be a little immature. Is Rika going to give it up, and how will Hajime react?
