is one who uses his brains more than his muscles. Not to say he is physically weak but that he thinks before he acts. He is the sort who tackles problems by thinking it through, listing out possible solutions and picking the most sensible and effective one. Perhaps it is this brainy planning which makes him seem rather sly and scheming. 
          Ikegami comes across as a dignified young man. He was a dependable and responsible, though not zealous vice-captain. He is a more academic- and probably career-orientated person. Interest(s) seem(s) to be of secondary importance to him. 
          However he is not all straitlaced seriousness. He is receptive towards people different from himself and possesses a rather dry sense of humour whose displays always surprise others (usually the readers). And for some unknown reason, I think he is quite talkative. Is it because he is not the shy type who hesitates to speak his mind?
