Which are your favorite episodes? I grouped them by story arc to make them fit in a poll.
My favorite is 17-18, because there's the most Grim Reaper material in the entire first season... I love those characters.
I also really like the episodes that Soma and Agni are in. My second favorite is episode 25, because it has Soma and Agni, as well as the Grim Reapers.
I've also watched episodes 3, 4, 5, and 11 a lot. Because Grell is in them.
What are yours?
