HsF-00

The HsF-00 is a giant supersonic fighter plane measuring about 80m in length first introduced in Volume 20. It can fly at a top speed of over 7,000 km/h and can perform highly unconventional flight maneuvers such as flying sideways or spinning like a top. As these maneuvers are very dangerous to the pilot, they are frozen at -70 degrees Celsius and their vital organs are connected to machines to preserve life. The computation abilities of the pilots are also enhanced by machines (similar to Accelerator) to compensate for the extreme temperatures.
