My Dress-Up Darling

Wakana Gojo is a high school student who dreams of becoming a kashirashi for hina dolls one day. Because his life is all about making hina dolls, he has a hard time fitting into his class because his interests are so different than anyone else’s. His classmate, Marin Kitagawa, is always at the center of attention and from another world. One day, they both end up on classroom cleaning duty and…

After seeing how passionate Marin is about the things she loves, Wakana decides to help her with making outfits. He decides to help her out in making a cosplay for Shizuku Kuroe-tan from the game "Slippery Girls 2." They had planned to reconvene later to get the measurements started, but Marin couldn't wait and ends up coming to Wakana's house over the weekend.

Marin and Wakana start to grow closer as he helps her create her cosplay. Though he's happy about the fact that Marin treats him the same way at school as anywhere else, he also starts to worry about the fact that other people think it's weird that they're hanging out. Despite that, Marin takes Wakana shopping so they can look for materials needed for her cosplay.

Wakana felt relieved just for a moment after they got all of the materials they needed for Marin's cosplay, but then he's shocked to find out that he needs to finish the cosplay in two weeks. On top of that, his grandfather, Kaoru, hurts his back, so Wakana has to run the shop and he also has midterms. Wakana feels overwhelmed and gets depressed, wondering if he'll ever actually become a kashirashi at this point.

Wakana finally completes the Shizuku cosplay. Marin is super excited that she gets to dress as her beloved Shizuku-tan and suggests that the two of them go to a cosplay event the next day. Even though it's her first time at a cosplay event, Marin gets requests for photos left and right. Wakana is overwhelmed with feelings as he watches over Marin, but...

Marin and Wakana have a successful first cosplay event. Because of something Wakana said, Marin's mental and emotional state starts to change a little. Even though she was just spending time at the Gojos' home with Wakana and Kaoru to wash her outfit, she can't seem to calm down. Meanwhile, a certain person comes to Gojo Dolls after seeing the photos Marin posted onto social media of her Shizuku cosplay.
