As siblings go, Atsumi and Atsushi are anything but typical. High schooler Atsumi is exceptionally small for her age, and elementary schooler Atsushi is abnormally tall with a deep voice, leading to misunderstandings on both sides! Whether Moriyama-sensei gets embarassed by Atsushi's every move, or Atsumi is offered candy meant for children, or poor Atsushi is arrested for being a perv that’s trying to snatch kids on their way to class, this brother and sister duo is bound to have an eventful day-to-day life!
Ever since Hikaru's sister started middle school, life around the house has been uncomfortable to say the least. For his cute little sibling, Fuuka, went through a massive growth spurt, making her exceptionally tall with monstrous breasts to boot. What's worse, the girl is determined to have her beloved brother take her virginity and have a baby with her! Will Hikaru manage to keep his busty sister at bay long enough for her to graduate to high school?
Two very short shows dealing with unusual sizes and siblings. Recorder to Randoseru has an older sister who is abnormally short and a young brother who is abnormally tall, while Cyclops Shoujo has a younger sister who suddenly grew due to puberty. Both include comedic skits with no real plot, so if you liked one, you may enjoy the other.
Short and episodic, both are about siblings with different personalities going through everyday life occurances. While Cyclops Shoujo Saipuu is by far the more perverted of the two (The only one that's perverted), they're both episodic and formulatic, keeping things mostly at status quo when the credits roll.
Both short series are about siblings who are very different from each other as they go through everyday occurances. Cyclops Shoujo Saipuu throws some ecchi perversion into the mix as well, something that Recorder to Randoseru doesn't dabble in.
Fuuka may have the voluptuous body of a well-endowed twenty-year-old girl, but in reality she’s only a fifth grade student. After her mother goes overseas to work, Fuuka moves in with her relatives – including the masturbation-obsessed, eighteen-year-old Jiro – and begins attending Tonbori Private Elementary School. Between meeting new friends such as Miki and Kenji, Fuuka finds herself learning about lingerie clubs, the best way to put on a swimsuit, and when it’s not a good idea to walk around the house naked. For a typical elementary school student, Fuuka’s not-so-typical body helps keep every day a new adventure!
Both shows are about elementary school kids who just happen to be in adult sized bodies. Yoiko has a girl main character and is way more pervy where Recorder to Randoseru has a male main character and is more lighthearted comedic fun. Check either out if you like young minds trapped in mature bodies getting into all sorts of trouble.
