Ovan

Ovan and Sakaki's first meeting is never shown. Neither is their second. Or third. In fact, the only time we see them interact is when the Azure Knights are about to eat Sakaki and Ovan remembers he left the oven on. But somehow, like all things Ovan, the scenes never shown but only implied create much of the plot's drama.

One of the questions driving at the members of G.U. for the duration of Reminisce is how Sakaki knew about them, as well as AIDA and Epitaphs. The answer is given during the final hours of the game at Θ Hidden Forbidden Dragonbein. It was Ovan who gave Sakaki AIDA and it was Ovan who told him about Project G.U. His reasoning is simple but incomprehensible: he needed Haseo to get stronger.

You would think Sakaki falling off a cliff and Ovan's avatar getting beaten by Haseo's would put an end to the new dynamic duo but you'd be wrong. They're back in volume three.

Sakaki returns as "The World"'s new system admin and, like before, pulling the strings and giving him plans in exchange for AIDA is Ovan. He tells him how to convince CC Corp to give him complete administrative rights over "The World" and scripts Haseo's arena battles. PKs he'd PKKed, PKs he'd been KO'd by, and even his friends and mentors were mysteriously pitted against him during the tournament. While I think these plans were all Ovan's doing, I also think the enjoyment Sakaki got out of humiliating Haseo is all his own.

After Sakaki is defeated during the Sage Palace title match and clensed of AIDA<Victorian>, he finds himself in an outer dungeon where he meets Ovan. Sakaki begs for another AIDA seed; he performed Ovan's script perfectly, he only needs more power, right? Ovan's only response is a cryptic glance and an even more mysterious remark before he logs off.
