Karen Kohiruimaki

The protagonist of this work. Born on April 20, 2006. Hailing from Obihiro City, Hokkaido. The youngest of two sons and three daughters in a wealthy family. Moved to Tokyo in the spring of 2025 to attend a prestigious women's university and lives alone in a luxury apartment owned by her sister and brother-in-law. She braids a portion of her hair on the right side.

Standing at 183 cm, her tall model-like figure draws attention, but her height is a source of insecurity. As a child, she was cheerful and lively with excellent athletic abilities, but unpleasant experiences due to her growing height made her become quiet and introverted. After entering university, her personality, combined with the environment of an elite women's university, led to difficulties in making friends. Concerned about her lack of social interaction, she decided to enter the world of VRMMOs as a form of rehabilitation for real-world communication, seeking a small avatar that contrasts with her real appearance, leading her to GGO.

Her avatar is about 145 cm tall, with stats focused on AGI (agility) and DEX (dexterity). The name is a play on her real name, but she has creatively altered the spelling to make it less common. Her main armament is a P90 (nicknamed "P-chan," voiced by Tomori Kusunoki) and a matte black combat knife (nicknamed "Na-chan"). In SJ4, she receives a dual-wielding gun "Vorpal Bunny" (nicknamed "Voh-chan") from Pitohui. In SJ5, she equips two Muramasa F9 light swords for a separate equipment switch system. Before meeting Pitohui, she used to dual-wield Vz 61s. As a hobby, she dyes her guns and camouflage clothing in desert pink, but she wears other colors if necessary.

She excels in close to mid-range combat, utilizing her small stature and AGI, often annihilating opponents before they can retaliate through ambushes and surprise attacks. Before meeting Pitohui, she had a period where she engaged in PK in desert areas using this strategy, becoming rumored as a mysterious and skilled PK. At this stage, she already had mid-level skills, and her fighting style was compared to Eastern Bloc assassins during the Cold War in the narrative. Just before SJ1, she honed her tactics further under M's guidance. She survived until the end in SJ3 but remains unaware of her own strength, causing confusion among those around her.

Unlike Miyu and Elsa, her approach to gaming is more casual, prioritizing real life. Due to the influence of the SAO incident, she keeps her gaming activities a secret from family members who tend to have prejudices against VRMMOs.
