Gamma serves as the fourth recruit and third seat within Shadow Garden's core leadership, the Seven Shadows. She manages the organization's daily administration and leads its administrative section. Publicly, she operates as Luna, president of Mitsugoshi Company, the highly successful commercial front and financial institution for Shadow Garden. In this role, she deciphers Shadow's vague descriptions of Earth concepts to create revolutionary products like chocolate, steam engines, and modern banking systems. Under her leadership, Mitsugoshi achieved significant economic influence, monopolizing fractional reserve banking in Midgar after the Major Corporate Alliance's bankruptcy. Her aggressive business tactics include predatory lending, market manipulation, and proprietary trading. Gamma possesses a slender, buxom figure with long, straight indigo hair reaching her lower thighs and a distinguishing beauty mark beneath her left lip. Her Shadow Garden uniform is a golden-accented slime bodysuit with a sleeved keyhole jacket and heeled boots. As Luna, she favors dark backless dresses with black or white heels. She exhibits a dual personality: publicly refined and shrewd as Mitsugoshi's president, while fostering a sororal bond with fellow Shadow Garden members. However, this composure shatters around Shadow or in combat, revealing chronic clumsiness that causes frequent stumbles, faceplants, and bloody noses. Her physical ineptitude, including difficulty walking in heels, earned her the private nickname "Gamma the Weak" from Shadow. Struggling with inadequacy over her poor combat skills and inability to anticipate Shadow's motives, she once contemplated suicide. Shadow redirected her focus to intellectual pursuits and organizational management, termed "Shadow Wisdom." She now channels her efforts into administration and interpreting Shadow's ideas, though she still aspires to fight alongside him. In combat, Gamma is the physically weakest Seven Shadow due to poor coordination and combat intuition, leading Shadow to abandon swordsmanship training. She developed a compensatory style relying on overwhelming magical power. She executes simple thrusts or swings while vocalizing "fwoosh" to amplify perceived severity. Despite unrefined posture, each strike channels massive energy capable of defeating multiple enhanced opponents. Her slime bodysuit offers near-perfect magical conductivity, and she wields slime-derived weapons like large swords or war fans. Paradoxically, she displays supernatural durability, suffering only minor pain from fatal attacks. She also serves as a rear commander, analyzing combat data and directing tactics. Gamma's intellect surpasses all other Shadow Garden members, including Alpha. She excels at multitasking, quantitative analysis, and large-scale operational coordination. Beyond managing Mitsugoshi's finances, she deciphers enemy strategies and transforms Shadow's fragmented Earth technology descriptions into functional products. Mitsugoshi's growth expanded her responsibilities, prioritizing corporate management over direct Shadow Garden activities. Her low alcohol tolerance is evident from intoxication via alcohol-laced chocolates. Her alias "Luna" was appropriated from the founder of Luna, Ltd. Her name follows the Greek letter sequence based on Seven Shadows recruitment order. At 17, she is among the youngest members despite her mature appearance and professional demeanor.
