Natsume Kyousuke

Kyousuke is the leader of the Little Busters, and is one year older than the other four members. He often comes up with absurd ideas, but almost always he follows up with a reasonable explanation along with it. He suffers from a lolita complex, though he denies it. He also suffers from a brother-sister complex, as he wants his sister Rin to call him onii-chan (meaning brother in an affectionate way), but Rin does not want to.

His alter-egos are Mask the Saitou(マスク・ザ・斉藤) and Tokikaze Shun(時風 瞬).
