Live action adaptation of the popular work featuring Otohachan, the poster girl of Circle Hiruneya. A story of a petite 146cm high school girl and her 2m tall boyfriend.









If you like size-difference sex, you have to watch this. It captures every reason why someone would want to have sex with a girl smaller than them. The way they recreated the angles and play from the original is god-tier; this is what a good live-action adaptation should be. The fact that it's consensual is the best part—Hiruneya-sensei really gets it. Usually, size-difference sex with small girls leans toward rape, but here, Otoha-chan is a perverted masochist who actively seeks out her big senior and goes at it until she breaks. A girl you can fuck as hard as you want is just the best.
Despite the negative stigma surrounding live-action adaptations in the manga industry lately, I want to shout that AV and erotic manga exist in a realm of super-synergy that transcends those norms. As a fan of both original manga series, I'm writing this for other fans and followers of Hiruneya-sensei to use as a reference. This work combines the two original stories and content posted on Twitter into one cohesive narrative—a true live-action adaptation. To start with the conclusion: it stays faithful to the source material in many ways while taking creative liberties that work well for the medium. The faithful points include the general scenario, Otoha-chan's height and youthful cuteness, the play, the dialogue, and the visual of the senior. While there are differences, they aren't negative. The breast size differs, but the overall body texture feels very close to Hiruneya-sensei's Otoha-chan. I enjoyed this 'younger' version of her. The unified scenario makes the flow easy to follow, and there's even a scene recreating an illustration from the recent art exhibition, which adds to the fun. Minami-san's acting is very natural, and the male lead fits the role perfectly. Whether you're a fan of the original or a newcomer, this is a high-quality adaptation that's well worth watching.
I was surprised at how well they captured the 'size difference fetish' from the original work. Just seeing petite Otoha-chan next to the giant senior completes the whole vibe. Hinano Minami’s atmosphere was just perfect. She looks innocent, but the way her expression breaks down was exactly like Otoha-chan! Her small frame makes the size difference stand out even more—it was enough to get me hard just looking at it! Personally, the standing 69 position that utilized their size difference was the highlight. A lot of these original-collaboration works miss the mark, but this one is a total win! I think you can enjoy this live-action even if you don't know the source material.
