Lost Weapons (異聞兵器?) are a type of being found within the Tunguska Special Territory created by Tamamo Vitch Koyanskaya.

Characteristics

Lost Weapons are recreations of individual hostile entities from the different Lostbelts. They exist for base defense and to be deployed in abnormal situations. Because they control the leylines, they keep reappearing every time they're slain and provide an inexhaustible supply of familiars. But their regeneration will be delayed for a while if they're struck down thoroughly. They are completely autonomous from Koyanskaya.[1]
