Season 1Cecil had always appeared to Nanami as a black cat,which Nanami named Kuppuru. When Nanami went to Saotome Acadamy's summer vacation trip, Cecil appeared to Nanami as Kuppuru and made her chase after him. Cecil led her into a forest, and into some ruins. He then appeared to her in his human form, saying that he has been waiting for Nanami. He explains that he is the prince of Agnapolis and that he and Nanami have met before in a past further away then the light of a star. Fireflies then begin to gather around them, and Cecil starts to sing.
