A kid looking to escape his families lot in life

(Yes, it's Roxas...)
Kero is what you'd expect from a 16 year-old, a confident kid that's a bit of a hothead. Unlike some, however, he isn't over confident, stemming from the fact that Nerima family has always been know for being weak as espers. This leads him to being smart was his powers and good and making bluffs. He also knows when it is time to cut losses and run. And usually, his feelings don't impair his judgment. But not always.
He wears the traditional black robes that the Nerima clan has been wearing for generation. His is a cloak that covers his normal clothes, and also wears black gloves.
The defining fact of Kero's history isn't actually from his life. It's from the history of the Nerima Clan. The Nerima Clan is infamous for having incredibly weak espers, a fate that seems to have befallen Kero as well. He has weak telekinesis that, even while weak compared to others' powers, he is one of the strongest Nerima's in generations. His motivation for becoming a Quester is twofold; one, he escapes his life of living at the whims of the more powerful people in his village in Antinium, and to revive the place of honor the Nerima's had in ancient times. Know one quite knows how a group as weak as the Nerima's ever had any power, but in times of old, the Nerima were one of the leading families in Antinium.
