Just a random doodle. 'Tis two characters, Takeshi and Kado (yes, his name is "gateway" for a reason), from a manga I'm co-writing, entitled "Kami wa Yami desu" (long title, ne?). Takeshi is saying "baka" (idiot or stupid).
Kado's t-shirt says "genki" (happy, good, etc.) on it. I have bad handwriting >.<
