Kyousuke Shiroyama is a summoner aligned with Freedom, one of the Three Great Summoner Powers. He's the recipient of Award #902, a recognition of his genuine talent in the field—though by all accounts, that talent comes with a serious catch.
The thing about Kyousuke is that he can't say no. He's plagued by this constant, almost compulsive need to help anyone who asks, which has become something of a problem for someone in his position. Whether it's a genuine weakness or just part of who he is depends on who you ask, but it's definitely taken a toll.
Right now he's juggling high school and his summoner duties, though "juggling" might be generous. He's seriously considering stepping away from summoning altogether—not exactly the career trajectory you'd expect from an Award #902 recipient, but the guy seems genuinely burnt out by the whole thing.
