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.

Marin is going to do a group cosplay with her idol, the cosplayer "Juju," whose real name is Sajuna Inui, and they're going to cosplay as Black Lobelia and Black Lily from the magical girl anime "Flower Girl Blaze!!". Wakana heads over to Marin's home so that he can borrow the "Blaze!!" DVDs for research to make the outfits for them.

Liz is a succubus who appears in one of Marin's favorite slice of life series, "SuccIDK." Marin had some interest in cosplaying Liz-kyun but didn't think she could pull it off until Wakana gave her a little push. With the cosplay ready, they head to a studio for a photoshoot, but the studio happened to be a rather unexpected location.
