H for Hikaru!
I've seen this game on other websites, but haven't seen a version of it here on toyhouse yet.
It's simple, really. Each person posts one of their own characters that starts with the next letter in the alphabet.
Ex:
person 1 : A is for Aname
person 2: B is for Bname
person 3: C is for Cname
etc. until you get to the end of the alphabet. When we get to the end, we'll just start over.
Feel free to either post in charater or link to the character you mention!
