The protagonist 「Nezu Tooru」is a 3rd year student and a member of an archery club. One day, during his way home a being that claimed to be a spirit fell from the sky and started to attack Tooru. The rampaging spirit grabbed Tooru by his neck and could have crushed it easily. At the moment when Tooru's consciousness about to disappear――

"I won't let you do it, Mugenjikuu!!(Illusion Space-time)"

The girl who also fell from the sky and was wearing the twelve layers kimono is called 「Kazamatsuri Shinmu」. Thanks to Shinmu's space-time technique, Tooru had survived but the spirit had now changed his attention to her.

"Stop!!!!"

Tooru grabbed the near by stick and hit the spirit in the head... However, the spirit was unscathed. Even though, it created a moment for both himself and Shinmu. Before the enraged spirit unleashed its attack, Shinmu's and Tooru's hands held time and at that moment...

"Busou Henge!!(Armament Transformation)"

The moment that the intensive heat that were too much to bear swelled up, the two bodies fused and radiated sparkling light.

"The evil doers are annihilated as the gale blows and the thunder roars. The apostle of bond and faith, Fuurai Senki☆Shinmu has arrived!"

Following, Tooru became Shinmu's armor and together managed to forced the spirit to leave.

To become Shinmu's armor in order to fight the Kagura power must be replenished. The only way to refill the energy is to make Shinmu feel good sexually.

Can Shinmu win the battle against the spirits whose goal is to corrupt the world and massacre human or will she succumb to the pleasure and fall...
