I think that they should develop more Yuno and his friendship with Haijima. Besides these 2 characters all of them should have a better development, since there are some that we don't know absolutelly nothing.
They should explain better Yuno's relationship with his cousins because I'm not sure if Yuno and his cousin are really close or not.
On top of all that the volleyball coach is a total mistery, but I really don't mind I kinda like it but they could drop some clues...
The animation has some flaws but since this isn't a big anime I think it's ok.
I think that the hole story has a big potential but it isn't explored.
