Bessho-san looks to his deputy, Colonel Satomi, who bows and says, "The exact nature of the device has not yet been determined. But it is clear from the extent of injury inflicted, that the devices used were of a type generally known as microbombs. A small quantity of high-energy explosive, often in gel form, combined with a detonator. The detonator itself may be linked to various bioware such as a pain editor or damage compensator, which monitor pain and injury to the body. The microbombs utilized here were sufficiently powerful to fracture the skull and deform the bones of the face, thus complicating the process of identifying the attackers."
