The purpose of this OVA is to give a some brief information about the characters archives and thema along with some eye candy and Arata's perverted acts. Arata needs to write a report on all the Trinity Seven in order to not get expelled from the school. The report aside, the OVA shows Arata at his perverted peak with all the Trinity Seven. And a little romance at the end as well as a hint of a progressing story completes this OVA. I wonder if it will get a sequel, since some new characters are shown in the ending scenes of the OVA.
