The instructor for the study of imaginary beasts, Balam Shichiro, can't help but touch any living creature he comes in contact with. Because he looks rather terrifying, the students are generally pretty scared of him. During class, Balam notices that Iruma doesn't have wings on his back.

Era uma vez,
Давным-давно… жили-были…
