Did your luck run a little low on the Mystery Boxes? Nekofuse has got your back!
By utilizing the Nekofuse system, you can convert multiple lower rarity Season Catgirls to a higher rarity Season Catgirl.
However, the Season Catgirl "Mae" asked that you please don't throw her into Nekofuse too much, since this will be very upsetting to her. (Just a joke).
