Oreki Houtarou's personality characteristics:
He has excellent insight and reasoning ability, but he thinks he is an ordinary gray high school student. Personal motto is "Don't do unnecessary things, do necessary things as soon as possible." I don't want to do anything that will drain my energy, and I'm not interested in campus activities. I think this is a waste of efficiency and not energy saving. Joined the Classical Department under the "coercion and inducement" of my sister Oreki Tomoe.
Playing the role of "detective" in various events, most of them can't get rid of their curiosity and trust in love. In order to smooth the avalanche of doubts about love, people often involuntarily follow the meaning of love and begin to analyze the mysteries of daily life, put forward the most possible assumptions and find out the truth.
Under the influence of "economism", there are few social activities. Even the members of the Ancient Books Research Association just kept continuous communication with Li Zhi, and to a great extent, they just stayed on the necessary familiarity with Moya and Ai Ju, and had no further friendship. The rest of the time, they knew almost nothing about their activities.
