Was A-chan Senpai from the Little Busters VN or was she a Kud Wafter original character? I hear she has made some appearances in the LB anime so I'm hoping some more Wafter characters such as the Arizuki sisters will make an appearance. On a related note, is there any chance that Kud Wafter could get animated after Little Busters? If not as a full series perhaps an OVA ep or two.
