One of the main characters from Battle Future F, Misu Gureisu, aka Hibiki Arisa. She stands out within her team, gaining attention for her unique fighting style and strength. However, growing tired of her teammates treating her differently because she's a woman, she begins taking missions alone. One day, she's suddenly ambushed and injected by the Venom Monster Man with a special serum that emits a unique scent only he can detect. Unaware of the injection, she's attacked again while on patrol. The Venom Monster Man had assumed she wouldn't transform, believing she'd endure the assault without revealing her identity as Misu Gureisu. But once Arisa realizes the truth, she decides to transform—however, the pre-transformation damage is too severe, and she's overpowered and defeated. Eventually, she's taken to Delos' base and held captive. When the public witnesses her abduction, the Venom Monster Man declares, "Whoever cums on this Misu Gureisu gets to return to the surface." What fate awaits her? [BAD END]
