Ayamine, Kei

彩峰慧

In Muv-Luv Extra, Ayamine is depicted as a quiet delinquent who mostly keeps to herself. She favors short, blunt remarks to provoke people and deflect conversation or tension. She holds a particular grudge against Chizuru and appears to enjoy getting under her skin. A free spirit with a somewhat selfish streak, she always looks out for number one. She enjoys skipping class to hang out on the school rooftop and has a strong obsession with yakisoba.
In Muv-Luv Unlimited and Alternative, Ayamine serves in squad 207 alongside Shirogane Takeru and the others. Her proficiency in close-range combat makes her well suited for the Storm Vanguard position.
She and Chizuru struggle to get along (Chizuru is severe and stubborn, whereas Ayamine tends to deflect serious comments with jokes and handle things her own way), which causes significant conflict within the team.
Her father, a former famous army general, was forced into a lose-lose situation where he abandoned his comrades to protect fleeing citizens. He was accused of fleeing under enemy fire and dishonorably discharged. This incident is the primary source of Ayamine's dislike for Chizuru as a leader, as she believes serving under an incompetent commander leaves only two options: fleeing or being annihilated.
However, after experiencing many significant events throughout Alternative, Ayamine begins to open up to her team and trust them with her life. This leads to a better friendship with Chizuru, as well as the rest of the squad.
