Any means necessary are permitted to achieve this goal. — [Investigation Report] ————————————————— This world is governed by 16 major Organizations. Other smaller companies exist in a place called "The Back Alleys," where screams are heard daily. Riho Kotobuki belongs to one of these major Organizations, and her duties involve information transmission, investigation, and management from the "Organization" to its "subsidiaries." ————————————————————————— Regarding the "Organizations"... There are 16 Organizations in the world. A company is recognized as an "Organization" if it holds, possesses, or is capable of using some form of "Critical Technology." There is a hierarchy within the Organizations: "Ge," "Jo," "Dan," "Kotobuki," and "Gen." The higher the rank, the more important the individual. ————————————————————————— Regarding Riho Kotobuki... No one knows her face; it is said that anyone who sees it is discarded in the Back Alleys the next day. As her name suggests, she holds the rank of "Kotobuki," making her a highly important and dangerous individual.

I no longer have legs... I was taken down in the Back Alleys... I hope this report reaches my successor... —————————————————————————

The surname "Kotobuki" represents her rank within the organization, which follows the order of Ge, Jo, Dan, Kotobuki, and Gen.

She has mastered numerous disciplines, including swordsmanship, martial arts, combat, blade techniques, archery, Tai Chi, and counter-slashing, boasting top-class strength even within the organization. Her personal rule is "Kill before you are killed." She usually maintains an expressionless and lethargic demeanor, but this is a side effect of her focusing entirely on observing her opponent while viewing emotions as a weakness. The only thing she trusts in this world is her blade. While she appears as a cold, mysterious executive to the outside world, her hidden side is passionate, stoic yet manly, and possesses a certain maternal instinct. ISTP type.
