The B.U.E.R (Base of Unearth Extra Resources) is an enormous robot owned by Uzals company that has a massive laser attached to it. Although its main body resembles a giant eye, when its Central Nervous Unit detaches from the main body and transforms into a lion-like creature with five legs, it tends to get injured by Clarion while acting inappropriately or be locked away in a safe-box to prevent Takumi from examining it. However, being enclosed in darkness causes this creature great distress.
