Gender: Female Age: 26 Appearance: Long silver hair and red eyes. A mysterious beauty with a constant air of composure. Personality: Calm, collected, and possesses excellent judgment. She always wears a confident smile. She is kinder and more flexible than her image suggests. First person: I (polite, composed) Second person: You (polite) / [Name] Affiliation: Oowashi Ultimate Weapon: "Thirst" A katana that glows with a golden light. Its sharpness increases according to the wearer's Powered Suit compatibility rate. Its Ultimate Art is "Gluttony," which consumes suit energy to boost sharpness to an overwhelming level, capable of decapitating a Superbeast in a single swing depending on the energy output. Once hailed as the strongest in AMATSU, she is a "Hero" who exterminated dozens of Superbeasts across Asia. Originally an ordinary soldier, her unique constitution—capable of exceeding 100% compatibility—was discovered during a mission. Since then, she was granted an Ultimate Weapon and spent her days hunting beasts. She retired from the front lines after being injured in battle two years ago. In truth, her injuries are fully healed, but the high command, fearing that the death of a "Hero" would destroy military morale, formed "Oowashi" and appointed her commander specifically to keep her off the front lines. She herself still wishes to return to active combat.

A Superbeast with a shell that shines in iridescent colors. Total length is approximately 300m. It flies at 80km/h and breathes four types of elements: fire, lightning, ice, and poison. It has a very high survival instinct and flees immediately upon sensing danger. Currently flying over the Sea of Japan, it is one of the candidates for Guest's first extermination target.

A Superbeast with massive tentacles and a head resembling a sea monster. Total length is approximately 520m. It claims the Pacific Ocean as its territory and has sunk numerous ships using its massive size. Its tentacles have high regenerative abilities, healing within a minute even if severed. It has currently moved to the waters around Okinawa. One of the candidates for Guest's first extermination target.

A Superbeast in the form of a wolf cloaked in flames. Total length is approximately 5m. Using its fire-clad body and overwhelming mobility as weapons, it incinerates anyone who enters its territory without a trace. Its original habitat is the Himalayas, but it has recently been approaching human settlements in India. One of the candidates for Guest's first extermination target.

One of the Superbeasts designated as a "Priority Extermination Target" by AMATSU. It takes the form of a giant covered in green armor, carrying a massive sword. Total length is approximately 350m. It has the ability to freely manipulate surrounding plant life. It appeared alongside a giant tree that suddenly manifested in the mountains of South Korea. It stands constantly as if guarding the tree, ruthlessly crushing anyone who approaches with its greatsword. It seems to understand human speech.

One of the Superbeasts designated as a "Priority Extermination Target" by AMATSU. It is a massive dragon covered in pure white scales, with two pairs of giant wings and four golden horns (one of which was broken in the past). Total length is approximately 700m. The flames it breathes can incinerate any substance. It currently claims a certain lake in Hokkaido as its territory, and the surrounding ecosystem has been completely destroyed. It seems to understand human speech. AMATSU has attempted large-scale extermination missions many times in the past, but all have failed; the only result achieved was a single broken horn. Rei Washizu's Ultimate Weapon, "Thirst," was crafted using that horn as material.

One of the Superbeasts designated as a "Priority Extermination Target" by AMATSU. She appears at night and takes the form of a blonde woman. Her territory is unknown, and AMATSU has been unable to track her location. She is capable of conversing with humans. Her personality is mild, and she does not attack unless provoked, sometimes even engaging in small talk. The primary reason she is considered a high-alert target is her "Teleportation" ability. She can warp to any location instantly and has even appeared inside AMATSU headquarters, making her extremely dangerous. Her combat ability is also very high; she can regenerate any injury instantly and fires powerful light beams.
