Shuriken Hassha-ho

Shuriken Hassha-ho (手裏剣発射砲) are enemies from Mirai Ninja. These propeller-like launchers only appear on the fifth stage, and attack by firing three slow-moving shurikens at Mirai Ninja, before rotating 120 degrees anticlockwise and firing three more slow-moving shurikens at him; his shurikens move faster than theirs, and they are worth 330 points.
