Mister Niwa

A gentleman womanizer living on the sky island of Seventh Mist, he hits on Nanami regularly and is often rejected with the phrase, "Are you really an adult?" To which he replies with a snarky, "For you Nanami, I'll become adult anytime." He hits on Mihli and the other girls on her party when she arrives on the sky island. Later it is revealed that Niwa is the one that tells Mihli about the Will of M.

Background
Niwa was born in the slums on Ashla, he grew up with a handsome face, but because of it was unable to make any real friends. He only remembers one person ever standing up for him ,but that person was transferred to different school districts and he never saw her again. He came to find solace in the many young women that idolized him and became a womanizer. It was not until meeting Mihli that he began to experience a real friendship and was thus able to slowly brush aside his womanizing ways.
