Takashima Yuna

Yuna's selfless nature leads to her trying to downplay her own background, and much of it was concealed in promotional material. However, she eventually reveals that she was born in Nara Prefecture, and on the day of the Vertex Disaster, she received her weapon at a shrine where she often played as a child. Yuna is a Hero and is therefore involved in the "war" her team is fighting, and she wants to end it sooner rather than later. She is also good friends with Koori Chikage. Her exploits would eventually cause girls who meet specific conditions at birth to be named "Yuna" in memoriam.
