An 18-year old classmate and childhood friend of the protagonist. He has a habit of making light of a harsh situation and is a deep thinker. He is an ordinary high schooler who has anxiety about growing up. He freaks out like a normal person trapped in all this end of the world mess. Although spineless when compared to the rest, Daichi always pulls an impressive feat when other people are in danger. Unfortunately, his low self-confidence doesn’t allow him to realize just how great he truly is. He has shown to have interest in several girls, particularly Io. He has some kind of hidden rivalry to Yamato, first because of envy of his maturity and reliability, but later because he disagrees with his struggle with Ronaldo about the best course for mankind, as he wishes for a future of cooperation instead.
