Before Moldiver's main story OVA series, a Secret of Moldiver! Confidential Encyclopedia! OVA was released. This featured background information into the Moldiver franchise, provided character designs, cast interviews but most importantly, had two short comedic episodes that were not reused in the main series.
The first episode (Go Go! Doll-chan) features Mirai working as a rollerskating waitress who encounters the Neophytes in their normal day jobs. At the end we are shown a preview for the 1st Moldiver OVA episode but the text on screen advertises all 6 episodes going on sale. The preview also features a bit of footage that did not make it into the actual final cut of episode 1.
The second episode (Project F) features the Neophytes working an undercover gig trying to get a MSX computer for Professor Arnagi's old technology collection.
