OTAKON. HELL YES. I AM SO THERE.
In fact, the next few weeks are gonna be a pre-con kandi-making storm, lol.
Sailor Raver, eh? Is that something like what you've got in your signature? That sounds completely EPICSAUCE.
In fact, I'll make something for you that says EPICSAUCE so that if I see you, I can give it to you.
Hoooopefully, by the time Otakon rolls round, I'll have made meself a pair of phat pants and a tie-dye t-shirt. The shirt will say "SMACK" on it.
... I wish I had the time and resources to make Dave.
... Dave the Death Note.
A backpack. That's pretty much. A big plush Death Note with the awesome face on it. And arms and legs, and a name tag that says "Hello, my name is DAVE".
