When his grandfather falls ill, some dude ends up inheriting the old man's model kit shop, which is already a weirdly specific setup for a hentai, but it works. The shop's in rough shape, so Risa, a regular customer who's really into model kits and happens to have a killer figure, volunteers to help out part-time. She's strict, reliable, and keeps things professional as they get the business back on its feet. Things are going well until one evening after closing, Risa starts casually changing clothes right in front of him like it's nothing. He panics, knocks over some mysterious solvent his grandfather cooked up, and it splashes on her. Whatever's in that stuff flips a switch in Risa's personality, and suddenly the dynamic between them shifts into very different territory. It's a 2-episode OVA from Studio Seven, adapted from a manga, and the whole thing leans into that mix of surprise and seduction without dragging things out. The mysterious solvent is a fun little plot device that keeps the setup from feeling completely generic. If you liked the character dynamics in Kanojo x Kanojo x Kanojo or the escalating scenarios in Oni Chichi, this hits a similar groove, engaging enough on the story side to not feel hollow, with solid animation carrying the intimate scenes. The professional-to-personal evolution between the two leads gives it just enough emotional texture to stay interesting across both episodes.
This season covers Chapters 1-2 of the manga. Continue reading from Chapter 3.

mumen_rider★★★☆☆EP 1The way Risa just started changing right in the middle of the shop caught me off guard and the animation for the spill looked surprisingly good
amikiri_amigo★★★☆☆EP 1I really liked the look of the shop and that scene with the homemade solvent was actually pretty creative
kaguya_sama_161★★★★☆EP 1That transition when her whole body started throbbing from the solvent was handled really well and it made the ending of the episode very memorable
ubagabi_usurper_93★★★★☆EP 1The plot with the grandfather's shop is a nice touch, and Risa being an otaku gives her way more personality than the usual female leads in these shows
jadeite_377★★★★☆EP 1Watching Risa switch from a strict part-timer to begging for help because of that weird chemical spill was a wild pivot for the first episode
goh★★★☆☆EP 1The tension when they were hanging out after work really got to me because that jar of liquid was such an obvious disaster waiting to happen
parella★★★☆☆EP 1You can really see the work they put into Risa and her design because she looks amazing even before the special solvent starts working its magic
gundamfreak★★★★☆EP 1The way she asked him to calm her down after getting soaked in that liquid was a pretty great way to start the action
sailor_mars★★★★☆EP 1That plastic model shop setting is actually pretty cool and Risa being a total nerd for it makes the whole spill scene way better
gohan_glory★★★★☆EP 1The detail they put into the plastic model kits at the shop before things got crazy was a nice surprise, and Risa is such a great character because she actually knows her stuff about the hobby. When I saw the protagonist accidentally splash that secret solvent on her it changed her personality so fast and the throb effect was intense
getsuga_tensho_463★★★☆☆EP 1Risa just stripping down right there in the shop was a surprise and then that solvent spill happened and everything moved so fast immediately
sakuramysunshine★★★☆☆EP 1I definitely was not expecting the grandfather to leave behind a solvent that turns people on but Risa looked incredible once it hit her skin
darunia_267★★★★☆EP 2Risa looked incredible in this one, especially when the solvent started taking effect and her face got all flushed while she was begging for help
sailor_mars★★☆☆☆EP 2the model shop setting is such a weirdly specific choice but watching her get all worked up over a spilled chemical in the storage room was actually pretty entertaining
raphtalia_raccoon★★★★☆EP 2seeing the way her personality flipped when that stuff hit her skin made me stare and I think the character designs are actually pretty high quality for this
kirishima_red_riot★★★☆☆EP 2that scene with the solvent bottle was wild and Risa losing her mind in the back of the shop was definitely a massive step up from the intro
modsoul_mystic★★★★☆EP 2I can't get over how good the animation looked when Risa was freaking out about the model paint and her reactions felt so much more intense this time compared to the first part
minako_aino_374★★★★☆EP 2Seeing the contrast between her strict personality and the way she acts under the influence of that weird grandfather solvent was the best part of the whole thing
