Yahaba is extremely loyal to muzan and is ready to do anything to become a member of the twelve kizuki. His blood demon art: Koketsu arrows allows him to launch arrows at his opponents through lime eyes with orange pupils with a black arrow pointing up on his palms. These arrows are shown to somewhat change the gravit of their target for a short while to launch and smash them against boulders, walls or the floor or push them away from Yahaba. Yahaba can control these arrows and their trajectory.
