Description
Hiroto is a character whose background and primary development are established in the preceding series, Gundam Build Divers Re:RISE, before his appearance in Gundam Build Metaverse. He is a 17-year-old high school student living in a coastal city who possesses exceptional skill as both a builder of Gunpla and a fighter within the Gunpla Battle Nexus Online (GBN) game. His avatar in GBN is designed to closely resemble his real-world appearance, often distinguished by a poncho that gives him a wandering, solitary air.
Prior to the events of Re:RISE, Hiroto was a more cheerful and sociable person, but a traumatic experience changed him profoundly. Two years earlier, he formed a deep bond with a mysterious girl named Eve, an EL-Diver, while exploring GBN. Their time together became his most cherished memory. However, during the Second Coalition of Volunteers battle, Eve was erased from the game's data in front of him, a fate Hiroto was forced to assist in by her own request to save the GBN system. This loss left him emotionally scarred, leading him to become a stoic and withdrawn mercenary who plays solo, logs in irregularly, and rejects rewards, all while secretly searching for any sign of Eve within the game's vast dimensions.
Hiroto's personality is defined by this internal conflict. He presents as calm and melancholic, a skilled strategist who is highly capable of analyzing enemies and planning missions. He is often seen as cold and distrustful of others, preferring to handle dangerous tasks alone rather than rely on teammates, which stems from his fear of loss and his guilt over past events. The name Build Divers is a particular source of irritation or anger for him, as it connects to the events surrounding Eve's disappearance and his own role in them as a former member of the elite Force, Avalon. Despite this guarded exterior, he holds a deep-seated belief that Gunpla possess something akin to a heart or emotions, a philosophy he learned from Eve, and he shows glimpses of a warm and caring nature, especially when encouraging others who share his attachment to Gunpla.
His role in the story of Re:RISE begins when he is reluctantly drawn into a mysterious mission with other Divers—Kazami, Parviz, and May—and is forced to become a member of a new Force named BUILD DiVERS. Over the course of their adventures, particularly when they discover the world of Eldora is real and not a game, Hiroto is compelled to confront his past trauma. He gradually learns to trust his new comrades, becoming their de facto leader and ace pilot, and finds a new purpose in protecting the people of Eldora. This journey transforms him from a detached wanderer into a committed team player who values collaboration.
Key relationships are central to his development. His lost love, Eve, is the primary motivation for his actions and his search throughout GBN. Hinata Mukai, his childhood friend in the real world, provides consistent support and is a link to his happier past, often encouraging him to re-engage with GBN. His bond with his BUILD DiVERS teammates—the loud but earnest Kazami, the gentle and flight-loving Parviz, and the logical EL-Diver May—is crucial to his emotional healing, as their reliance on him and his on them slowly rebuilds his ability to connect with others.
Hiroto is renowned for his Gunpla, the PFF-X7 Core Gundam, which he designed and built himself. Its defining feature is the innovative Planets System, a modular design that allows the small Core Gundam to dock with different armor sets, each named after a planet and optimized for specific combat scenarios. These armors include the all-purpose Earthree, close-combat Marsfour, long-range Veetwo, underwater Mercuone, space-combat Jupitive, reconnaissance Uraven, demolition Saturnix, and high-speed Nepteight. His fighting style is analytical and strategic, often involving the use of traps, terrain analysis, and coordinated attacks, reflecting his preference for control and preparation.
In Gundam Build Metaverse, Hiroto returns and demonstrates his continued growth as a builder and pilot. He develops a new addition to the Planets System, the ninth unit known as the Pluto Armor, which forms the PFF-X7II+/P9 Plutine Gundam. This black-armored unit is designed for dueling and close-quarters combat. Its unique EP Armor, made from recycled Ecopla materials, can convert kinetic energy from the unit itself and nearby enemies into supplemental power, allowing for extended combat sustainability. The Plutine Gundam is armed with a multi-form scythe called the Infortune Scyzer and shoulder-mounted Breaklow Feather units that can be used as remote weapons or claw-like armaments, showcasing Hiroto's ability to adapt his engineering skills to new challenges while honoring the core principles of his original design philosophy.
