He is just reffered as "That guy" or "pigeon guy" by Sakurai Tomoki and he always appears in summer when there is a festival, were he always has one prepared already with the name of "JUDAS" at the top. He is always shown with pigeons reffering how he is introduced in the JUDAS manga (a big cluster of pigeons over him).
