In shogi, Demon Slayer or Demon Killer (鬼殺し onigoroshi) is a trap opening initiated by Black (先手) that characteristically advances their left knight (桂) blocking their bishop's diagonal (角道).

Later moves attempt an attack using a further advanced knight and also possibly against White's left silver (銀).

If defended against properly by White, then it puts Black in an unfavorable position.

Therefore, it is designed to trap novice players.
