Character:

Mikado Ryuugamine's childhood friend and resident of Ikebukuro. Kida is an easy-going guy and appears foolhardy at times. He is 15 years old and is in class 1-B.
Mikado says that Kida used to be very energetic in elementary school and describes him as being quite charismatic. Kida seems to know many of the residents of Ikebukuro which he credits to having his nose in too many places during middle school. Nevertheless, he functions as a guide to Mikado.
