Nendou Riki

Riki Nendou (Japanese: 燃ねん堂どう　力りき, Hepburn: Nendō Riki), one of the main characters of Saiki Kusuo no Ψ Nan, is a dutiful and dull-witted boy. He likes helping people and aiding the weak,[4] and though his silliness annoys his classmates, his motives are mostly well-intentioned. His appearance is made very distinctive by his exotic haircut and oddly defined chin. Riki was played by Arai Hirofumi in the live action movie version of the series.
