Hooligan

The series begins with Yukito's attempt at a romantic encounter with Olga, which is interrupted by the detonation of one of her scientific devices. This event causes a significant disruption to the space-time continuum. The only means of restoration is the collection of seven specific artifacts, each held by a different young woman. Yukito must engage in intimate competitions with each guardian, including the shrine maidens Yuka and Yuki, the ninja Victoria, and Hiromi, prevailing through stamina to claim each item. His success in these encounters is necessary to repair the fabric of reality.
