|Japanese name:||右代宮 戦人|
Battler is also an extremely rational young man, and has an extreme talent for deductive reasoning and thinking outside the box, described as "flipping the chessboard" so that he may be able to predict the moves and motives of his opponents. Because of this, he does not believe in witches or magic. This causes some conflict with his cousin Maria, who has immersed herself in studies of the occult and believes strongly in witches, especially the Golden Witch Beatrice.
Six years prior to the start of the series, his mother died and his father remarried almost immediately. Battler had a falling out with his father, disturbed by how fast everything went, and rebelled against him, cutting all ties to the Ushiromiya family to live with his maternal grandparents for the next six years. After his grandparents died, he returned to his old home. His relatives held no ill will towards Battler for running away, save for Kinzo; in fact, Battler was able to rekindle his old relationships very quickly. However, out of fear of how Kinzo would react if it was brought up, reference to his rebellion is taboo.
Ironically, despite his disbelief in magic and witches, Battler has very strong magical powers. He can generate a barrier that offers him great resistance to anything magical in nature, which serves as the main contributing factor to his denial. As such, he serves as a natural enemy to Beatrice and other witches, since they draw power from those who believe in it. Battler's resistance is thus put to the test by Beatrice, who bombards his sense of logic with countless scenarios that seemingly can't be explained by human means in the hopes that he will ultimately surrender his position and accept her existence. He has in fact neared a breaking point many times, but barely manages to regain his composure and strengthen his magical defenses each time, now to the point where his barrier is nigh indestructable, a perfect shield perhaps not even gods can ever hope to penetrate.
