Ultrasonic Weapons (超音兵器 Chou-on Heiki?) are weapons that use ultrasound to injured, incapacitate, or kill an opponent.


Ultrasonic hand held grenade launcherEdit

During Tsuchimikado Motoharu's rampage of revenge against those who "killed" his sister, Tsuchimikado Maika, he came upon a man who used a hand held grenade launcher. The ammunition that was used did not produce a normal explosion like a normal grenade, instead it produced a high-pitch whistling sound.[1]

The weapon had been developed for quickly suppressing an enemy in a location such as a museum or armory where secondary damage had to be avoided at all costs. The use noise it would produce would tear apart the lungs from the inside. Anyone who is hit directly bit will drown in their own blood. It uses a timed fuse of between 3-5 seconds and has a parabolic trajectory.[1]
