He is in a position to teach Yukari and the others. He believes in Spartan education, and is respected by Yukari and the others. In fact, since childhood he had a secret dream of becoming an astronaut, but when he took an aptitude test to join the SSA, he was found to have slight signs of arrhythmia, and was deemed unsuitable, so he gave up on his dream.
