Never get between a chimera and his coffee. One of Zelgadis' many little quirks is that regardless of what anyone else is drinking, he'll be found imbibing caffeine. I guess we depressed folks need all the "up" we can get, neh? Unlike a lot of the in-your-face running gags in Slayers, this one is a quiet little joke that's never made a big deal of but which follows Zel around from start to finish. Another great Nan Desu Kan 2005 find.
