Tetsuro Tanaka, a typical shy and earnest boy is struck with tremendous shock when he walks into his new school, The Gokoh Academy. It is the venerable woman's garden and no other male student exists except him! Aghast and horrified, Tetsuro is at the mercy of incredible incidents from the first day at the school. Flying robots, bare knuckle fighting, winged girls, squirming hair. Gleaming foreheads! And the baby-sitting striking angels! "We guard Tetsuro forever!" Tetsuro finally gets to the boarding house where 6 beautiful girls welcome him. Wow! He is going to live with the gorgeous goddesses under the same roof!

Miya Towano (called Miya-sama) is the reigning chairman of the student council at Gokoh Academy. She is the leader of "Gokoh Club (Gokoh-Kai)," a group of elite students of the school. This letdown and good-for-nothing boy Tetsuro is nothing but irritation to Miya, as she cannot stop feeling temptation "I want him to obey." 'Queen' Miya accompanied with her followers comes to tease Tetsuro today, too. Our Koi Koi Seven intercepts her naturally. Unification (Robot and machine)! Destruction! Grueling battle! Well, then, what is the outcome of this all-out war?

Gokoh Academy is primarily a peaceful women's paradise. Suddenly, a mysterious man called 'Brusera Mask' forces in and knocks the entire school down to the abyss of terror with his slightly obscene approach. In this crisis, Akiwo Suzuki, the nerd of Special Effects of Koi Koi Seven, stands to stop him. "Power-boiling Rangers! - Only Red enters due to inevitable reasons." Dressed up in the sexy suit, Akiwo faces up to Burusera Mask ... for someone in her heart and/or to save all the students...

On a rainy day, Tetsuro goes out to meet Otome as he is told strictly not to let her get wet. Otome Konno, the brain of Koi Koi Seven, has a big secret. "Are my hands warm?" Tetsuro is surprised to check Otome's temperature. She invites him for a hang-around on the way back home and takes Tetsuro to a soggy puppy in a cardboard box. What does she intend to do for this dog?

All of a sudden, a gigantic elevator soars up in the sky of new frontier coast. And on the top of this towering elevator, 'Queen' Miya Higashikazuno is laughing loudly in the center of swarming girls in extra-tight bikini-suits. What a splendid view! It is the Sports Day in swimming suits commemorating the completion of the orbital elevator. The girls wrestle for the first prize of one million yen sponsored by Higashikazuno Zaibatu (an industrial conglomerate). Will there be accidental 'glimpses' then? --- "We can repair our shabby boarding house if we have this money."
