Heavy Acceleration Reducing Machine

Heavy Acceleration Reducing Machine (重加速軽減機) is a backpack/metal-detector-like devices developed by Rinna Sawagami for Genpachiro Otta's use as means to fight against Roidmudes while evading Heavy Accelerations induced by them. Much like the Heavy Acceleration Particle Measuring Device, it was called Pikopiko 2 (ピコピコ2号) due to the blinking noises it made. It was first introduced in episode 12.

After the original's destruction by Judge Roidmude, Rinna repaired it and made several modifications such as the addition of electric-proof vest. This gadget was later named Pikopiko 3 (ピコピコ3号).
