Natsuki Nanba

Character appears in Haru-iro Astronaut. Natsuki is a childhood friend of Yuu. He is a nice and caring guy, but he is very bad at defending his desires and interests when they clash with someone else, preferring to give up. However that still hurts him even though he tries to hide that. Yuu doesn't like that trait of his, and always tries to help him so he won't be so weak-willed.
