Koi Koi Seven was serialized in Akita Shoten’s Champion Red line of magazines from 2002 to 2007.

## Plot

Tetsuro Tanaka is transferred to Gokoh Academy full of high expectations. However, expectations fade with a bad premonition the moment he steps onto the campus and finds all the students except him are girls. A series of strange events fall upon him. Then, six girls who are called Koi Koi Seven appear as his guardians. Army combat helicopters and anti-tank guns attack Tetsuro for no particular reason as he tries to survive each day in the academy. Surrounded by many girls he gets into trouble every day because he often sees them naked, usually by mistake. In the dorm the same problem continues with the Koi Koi 7 team walking around the house in their underwear. On top of this, Celonious 28 also chases after him all the time because she wants to be with him. As well, Asuka Yayoi feels jealous of him because she loves him and she doesn't want him to hang around with other girls, which is very difficult because he is the only boy in the school and the girls are after him all the time. In general each girl of the Koi Koi 7 team has secret feelings for Tetsuro but they don't show them.

Kano overhears and reports the conversation to the headmaster. At school, Miya snares and ties him suspended over the pool. Tetsuro is forced to watch from this position as the girls compete for him, first swimming a medley relay, then wrestling "Mongolian-style" (the objective being to strip the pants from one's opponent), and finally in a volleyball game. The Koi Koi Seven win every event: witnessing their determination, Tetsuro admits that there is something to be said for girls who go to such extent for his sake. Still not satisfied, Miya reactivates her mecha, merging all five into a super-robot, only to be humiliated by a malfunction. Celonius 28 makes her first appearance, floating alone in the pool, calling Tetsuro's name. |||

| While preparing for the school festival, Tetsuro's uniform and glasses are destroyed in a painting accident, so Yayoi dresses him up in a girl's uniform. Miya is taken by this fresh-faced newcomer, adopting "Tetsuko Nakata" as her younger sister, and insists that they exchange ribbons. The members of Koi Koi 7 convince Tetsuro to return the ribbon, which he does reluctantly, knowing Miya will be crushed -- and she is, attacking yet again in a giant robot. Celonius 28 has by this time infiltrated the school, and posing as a student, saves Tetsuro from Miya, kissing him before disappearing once again with Kano hot on her tail. |||

| On the day of the festival, Tetsuro is pressed into service at the class's maid cafe, once again being forced to cross dress. Tetsuko's reappearance as a maid brings Miya to the cafe, but Tetsuro is saved by Celonius 28, who whisks him away under the cover of a blackout. Yayoi happens upon the couple in the garden and the two Yayois confer privately. 28 attacks, defeating the Koi Koi 7 by exploiting their weaknesses, but when she slaps Tetsuro aside for attempting to intervene, Yayoi rises again and, saying that she will always protect Tetsuro, immolates 28 in blaze of brilliant white light. Tetsuro begs Kano to save 28, so she installs 28's program in one of Otome's spare bodies. |||

Feeling out of place, she wanders off without telling anyone and finds her way to the school, where various scenes trigger disturbing flashbacks. Kazuko, Chuko and Yuko discover the lost child and bring her to Miya, telling Miya that this is a good way to polish her image, but Miya isn't very good with children. Gentai runs away and is spotted by Tetsuro, who has been searching for her, but she runs away from him too. After she finally stops, they run into Izuma and Subaru, who call Tetsuro a two-timer and a lolicon when they see him holding hands with a little girl. |||

| Hifumi is not acting like herself. She seems to have heard the scream of a mandoragora, and will lose all memory unless she eats the mandrake root raw. Mifumi's alternate personality irritates Kazuko, who plots to humiliate her, first soaking her school uniform, then dressing her in a robotic nurse's uniform that forces Hifumi into erotic poses while Kazuko takes pictures. Somehow Mifumi remembers Akio's name long enough to scream for help, but her personality is not restored until she eats the raw mandoragora. |||

| Having decided not to disband after all, the Gokō 5 pick one last fight with Koi Koi 7. Their poor timing results in Kano giving all 12 of them cleaning duty for punishment, but then all the girls in school start chasing Tetsuro, and Yayoi is abducted by two advanced Celonius cyborgs. |||

| The gate to the other world is open, and it appears to be some kind of tropical paradise. Tetsuro frolics in the waves with Gentai and two other young girls. Kano suns herself on the beach, and the Koi Koi 7 play in the sand. Izuma and Subaru rub each other with suntan lotion. Offshore a sinister submarine lurks: Gokō 5 is at it again, but beats a strategic retreat when Otome gets wet. When Otome's unconscious body is beamed up by a UFO, everyone goes off in pursuit, but they are distracted by the discovery of an onsen, where the decisive battle ultimately takes place. |||
