Random Number Ultrasonic Blade

Mechanical Arms


The Random Number Ultrasonic Blade is an Academy City prototype weapon used by Disciplinary Action, a rogue Anti-Skill group. It is a portable weapon that's kept in a backpack by the user. The user needs only to click their backpack, at which point the weapon disengages from it along with segmented connectors and pads that equip themselves on the user. The weapon in earnest takes the form of a long cleaver-like blade that displays immense sharpness, allowing its user to easily cut a wall to pieces. The blade can still be used even if the backpack's mechanism is destroyed, and the segmented connectors can then be repurposed as a pair of extra mechanical arms, capable of lifting and carrying a young girl.
