hooray for weird mould defying anime :)
I really liked this anime although the artwork might not have been the best and sometimes it is hard to entirely understand the main character. ;p Maybe that's 'cause I'm not a tanuki?
Personally I liked the second season more than the first season because the first season was struggle street for pretty much all of the main characters. And while you got really attached to them it also felt a little frustrating.
The second season definitely changes things up and unravels a lot of the mysteries that underlied actions/backgrounded characters in the first season. As well as fleshing out almost all the main characters.
I think they could definitely still do a good 3rd season. There is enough mystery left over from the first season as well as a couple of new mysteries and threads started in season 2.
