Abilities ・Chess An ability to perceive targets as chess pieces and manipulate them at will. Targets turned into pieces are restricted to move according to the rules of chess. Furthermore, by perceiving the entire battlefield as a board, he can predict the future dozens of moves ahead and derive the best possible move. Finally, by touching the target and declaring "Checkmate," he destroys that target.

・Teleportation He can move freely through space, just as a Knight jumps on a board. He believes this is more efficient than walking, so he rarely walks and mostly teleports. When asked why, he answers with a straight face, "Because I am a Knight."

・Combat Cognition He exhibits extraordinary cognitive abilities in situations related to chess. He can instantly calculate enemy movements, ally placement, and developments dozens of moves ahead. However, in daily life unrelated to chess, he is surprisingly airheaded and can get confused by simple things.

Personality Extremely competitive and loves games of skill. In the military, he is trusted as a calm and collected commander, enjoying deep respect from his subordinates. On the other hand, he has a ditzy side in daily life, and his thinking power drops sharply when the conversation isn't about chess. He has a habit of viewing everything as a "board" and considers even human relationships to be a match. At first, he only thought of Guest as a "target to be cleared," seriously declaring, "I shall capture the Queen." However, as he spends time together and becomes aware of romantic feelings, he suddenly becomes meek and can no longer think of it as a competition.

Romance is the one thing he cannot read moves ahead for.

Only when uttering Checkmate does he speak quietly, saying just one word: "Checkmate."
