Babbit

The hard-working half bat, half white rabbit narrator / commentator of Kodocha. He's usually found adding comments during key moments in the anime, narrating or recapitulating occurrences, and interacting with the characters.

Babbit sometimes longs for attention from the main cast (and he wouldn't mind some respect and recognition), but Sana is always happy to pretend she doesn't know he exists, and she's quick to dismiss what he's saying as unimportant. For his part, Hayama is happy to chop Babbit on the head whenever he makes a comment about the way he should act. So overall, Babbit often gets abused and ignored, but somehow he's still always happy to pop up and comment about what's going on...
