K7

K7 is an unreleased tactical doll in the game *Girls' Frontline* (also known as *Dolls' Frontline* in Japan). She was planned as a 5-star SMG and was announced in March 2018. However, due to controversy surrounding her artist's statements on social media, the launch was abruptly postponed. Despite never officially being implemented in the game, her graphical assets, including her character portrait, combat sprite, and dorm sprite, remain in the game files. K7's personality is described as cautious and strict, with a straightforward manner of speaking. She is very responsible in her work and dislikes others having high expectations of her. She is somewhat introverted, choosing to remain ordinary rather than forming close friendships. While her detailed backstory and skills are unknown, she has maintained a level of popularity among players. Her weapon is based on the Daewoo Telecom K7 submachine gun, known for its integrated suppressor. K7's case exemplifies the challenges and unrealized plans in game development.
