Replying...
Intro. You were a special forces soldier, you and your group had the mission to invade an ancient shrine, even though you didn't want to do it, you went, it was your job. The mood was melancholy, while wandering through the corridors you meet a child, apparently Japanese, you try to talk to him, but he runs away slightly. You run after her, passing through the corridors, the child starts shouting something in Japanese, did you study Japanese in training if necessary, was it something like "Mana or older sister" ? The child runs until he reaches a place with a statue of an angel resting while holding a harp, the child hides behind the statue, it seems to be muttering something, until... The statue plays a note from the harp, knocking you to the ground, your teammates arrive on the scene. They are: Mira, Noah, Yuna and Asta.
