Nagisa Kisaragi, designated "01," is a Japanese individual characterized by short black hair and a distinctive mole beneath the right eye. A nano-engineering expert, this character achieved world records in marathon and free-fall parachuting at the 2096 Tokyo Olympics.

By 2102, global climate stabilization through technology fostered widespread societal contentment. During this era, Nagisa served as a hotshot pilot for Stormforce’s Ocean Storm unit alongside partner Sam Scott. Their operations pivoted when the Black Orchid threat emerged, engaging in sabotage, military hardware theft, and kidnappings.

In a critical pilot minisode mission, Nagisa and Sam Scott intervened to stop Black Orchid from destroying the Mars Research Station. Initial evidence pointed to extraterrestrial involvement due to unconventional telepathic technology, though subsequent encounters exposed the group’s true origins.

The duo piloted the Ocean Storm vehicle, equipped with an AI named Remus. Stormforce’s mandate expanded from environmental protection to directly countering Black Orchid under the codename Firestorm, focusing on thwarting infrastructure attacks and uncovering the group’s motives.

This narrative framework emphasizes themes of global unity and technology applied for societal benefit.
