Ren Akiyama and Ryo Akiyama are not actually related. But a family tendency for amnesia would explain things. Hell, for all we know, he really could be the older brother of Ryo Akiyama from Digimon, and just transplant all of the Wonderswan game backstory there to justify why he doesn’t have a past until then. No, I’m not writing a fic. Why do you ask?

A certain Tamer that's one of my favorites-not meaning Takato in this case-wouldn't be amused by this one bit. Me on the other hand...

Btw, you should see about getting Sinister Plan (TM) trademarked. ^^
