Hikoboshi II

Hikoboshi II (ひこぼしⅡ号) is an Academy City spy satellite officially referred to as a weather satellite.

Background
It can observe Academy City and the surrounding area in excellent detail. It also has a large caliber ground-attack laser installed on it. The experimental laser is an optical bombing weapon that uses white light waves. It heats its target up to about 4000 degrees, but white light waves have the power to destroy cell nuclei just like ultraviolet rays, so it can cause cancer quickly. It's range is a 5 meter radius to a 3 kilometer radius. It cannot fire in quick succession and can barely manage one shot in an hour. Also the atmosphere randomly refracts the white light waves, so there is also a slight margin of error in its accuracy.

Battle Royale Arc
GROUP discovered that the the Control Center for the satellite was being cracked. Due to this, Accelerator split off from the rest of his teammates, who were heading towards the western External Connection Terminal, in order to destroy the antenna controlling the satellite in order to prevent SCHOOL from gaining control of Hikoboshi II. On the way he found out from "Unabara Mitsuki" that is was BLOCK behind the crackings and not SCHOOL like they had originally assumed. They originally thought that BLOCK's plan was to use the laser weapon on the satellite to attack District 13 of Academy City as it contained a large number of kindergartens and elementary schools. If this was done then a large number of kids would die and parents would be too afraid to send their children to Academy City which would weaken Aleister Crowley. However it was later discovered that their true plan had nothing to do with the laser and was instead for the antennae to be destroyed which would disable both its attack and surveillance functionality. Accelerator eventually made it to and destroyed the antenna which inadvertently weakened Academy City’s defense capabilities as they lost the satellite's surveillance network.
