Ryujin and Rain have a sibling bond

Okay, so this is something I thought would be super cute by making Ryujin and Rain have a sibling like relationship during the SAO Death Game, what do you guys think?^^

First, Rain is one of my favorite characters from the SAO games, and I was sad that I wouldn't be able to use her because the games are non-canon/alternate timelines or a "what if" kinda thing. But as I remembered, Rain was in SAO as a survivor, and I got to thinking, Rain could be easily added to the Sao anime/light novel, in my option anyways (and yes, I'll bring Seven is too)

So Rain and Seven are the only "non-canon" characters I'm gonna use in my series :3
