Koi Koi Seven - Season 1 (2005)

It rains. Otome gets wet.

Miya hosts a swimsuit competition to celebrate the opening of her space elevator at Odaiba. The Koi Koi 7 girls enter because they need the 1 million yen cash prize to repair the house after it was damaged by Miyabi's hair.

Sakuya has to make an anime on an impossible deadline.

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.

On the day of the festival, Tetsuro is pressed into service at the class's maid cafe, being forced to cross dress again.

Gentai is bored. Feeling out of place, she wanders off without telling anyone and finds her way to the school, where various scenes trigger disturbing flashbacks.

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.

The Koi Koi 7 fight their way through Miya's Cattleya Castle to reach Gentai.

Having decided not to disband after all, the Gokoh 5 pick one last fight with Koi Koi 7.

The gate to the other world is open, and it appears to be some kind of tropical paradise.
