Yeeeah girl

A character in a dark robe casts a bright green spell, followed by a scene of two young men in school uniforms smiling in a forest, then a confrontation where one man grabs another by the collar on a hillside overlooking a village, then a young woman with a determined expression in a dimly lit tent, then a close-up of a young woman with a bloodied face in a dark forest, and finally a young woman running through a forest.
