Nenji Nagihara

Nenji Nagihara is one of the main protagonists of Nanaka 6/17. He is Nanaka's classmate and childhood friend. He is a delinquent, but after Nanaka's accident, he seems to settle down quite a bit. Nanaka's father asks him to keep Nanaka's accident secret from other people and take care of her at school. Nenji is occasionally referred to as 'Wild Hair Nenji' by some of the other characters because he has long, spiky hair reminiscent of certain stylized Shōnen anime characters.
