Nabi (There she is!!)
Ace of spades-e14
The white cat in the "There she is!!" series. He is obsessed over by the love-struck Doki, a white rabbit, however due to inter-species relationships being taboo in their world he is reluctant to return her feelings. The series is a heartwarming testimony to the power of love which I highly recommend you watch.
