Description
Kyosuke Nanbu is a 22-year-old male known for his quiet, reserved demeanor, often appearing cold and unemotional. This stoicism contrasts sharply with his girlfriend Excellen Browning's cheerful personality. Despite outward apathy, he deeply cares for Excellen, though he sometimes ignores her affections. He possesses an exceptional ability to remain calm and make quick decisions in combat, piloting the unbalanced mecha Alt Eisen effectively where others cannot. His personality includes a short temper that emerges unexpectedly during intense battles and a notable gambling habit, frequently framing conflicts as high-stakes bets with his catchphrase, "I don't mind betting with hard odds."
A defining aspect of his background is a shuttle accident in his youth that killed all passengers except him and another individual, whom he shielded from the wreckage. This event granted him unnatural, inhuman luck enabling survival in near-fatal situations. Examples include emerging from the Wildraubtier's destruction during a test run with only broken ribs and surviving severe combat encounters others could not. This luck is integral to his survival and combat effectiveness.
He joined the Earth Federation Army and was recruited into the ATX Team by Sanger Zonvolt after the Wildraubtier incident. Initially a member under Sanger, he assumed leadership following Sanger's betrayal. He maintains respect for Sanger despite the latter's actions, confronting him openly in battle. Kyosuke relies heavily on intuition during combat, which consistently proves reliable and allows him to outthink opponents. His combat style involves charging head-on as a "tanker," utilizing the Alt Eisen's durability and close-range arsenal to minimize damage while overwhelming enemies.
His primary mecha, the Alt Eisen, is a prototype Gespenst MK III deemed impractical for mass production due to weight and design flaws. Its callsign, meaning "Old Iron" or "Pig Iron," references its scrapped status. Kyosuke pilots it effectively despite limitations, wielding weapons like pile bunkers and revolvers. The machine was later upgraded to the Alt Eisen Riese, which requires a Tesla Drive to stand due to weight. Both units feature close-range-focused arsenals, including the Alpha Strike attacks "Trump Card" and "Claymore Overlord," which unload all weapons at point-blank range. These attacks are often impractical without logistical support. His combat prowess is enhanced by combination attacks like "Rampage Ghost" with Excellen's Weiss Ritter and "Code E.D.N." with the Flickerei Geist.
His story spans multiple conflicts. In Original Generation, he defends Earth during the Divine Crusaders War and Inspectors invasion. He develops a rivalry with Axel Almer of the Shadow-Mirror universe, whose leader, Beowulf, is Kyosuke's evil twin. Kyosuke persuades the Einst entity Alfimi to rebel against her creator, weakening the alien threat. In Original Generation Gaiden, he experiences a Heroic BSoD after failing to protect a friend, resolved only after Axel rescues him. Later, during a training exercise with Ryusei Date, he disappears into a dimensional rift, arriving in the world of Eria. After resolving events there, he transports to the subterranean realm of La Gias, joining Lune Zoldark and the Steel Dragon Battle Group against new enemies. Upon returning to the surface, he confronts factions like the Gaia Sabers and Ruina, though his role becomes more peripheral in later conflicts.
Key relationships include his Battle Couple dynamic with Excellen, whose synergy allows seamless coordinated attacks. He serves as a Big Brother Mentor to Ariel Org in later adventures, even sharing a combination attack. His survival instincts and tactical acumen cement his reputation as a Determinator, summarized by Sanger Zonvolt's observation that he "charges headfirst into danger and always finds a way to win." This tenacity is exemplified in his declaration: "It doesn't matter how thick your armor is: I'll pierce it."
