Clow used to be a Tori-Agent, and he was a leader of a clan back in the day. So he wasn't always some "mysterious person no one knows about".

Now on topic: Pretty much my closest TB friends is everyone in [duck]. Known them for years, and are always a blast to be around.

Jaker's also pretty cool too. He was (and still is) pretty much my rival back in 2011-2012. Despite that, we're still pretty good friends.
