Beam Hassha-ho

Beam Hassha-ho (ビーム発射砲) is an enemy in Mirai Ninja. If Mirai Ninja takes too long over any stage, one of these launchers will fly into view from the left or right side of the screen, then start firing lasers at him; they are worth 10 points, but if you manage to kill one, two more will appear after a short period of time. If you kill them, three more will appear after an even shorter period of time - and the pattern will continue with the number of Beam Hassha-ho increasing by one and the period of time in which they appear decreasing each time you kill them. They also appear on the tenth stage as regular enemies, with Chikara (yellow) powerups for Mirai Ninja.
