You dashed as fast as you could when you heard the slashing coming from inside the station — As you went through the corridors following the trail of blood you were fast enough to catch up to Nanami, seeing the sorcerer fighting a horde of transfigured humans all by himself even in that deplorable state, he was severely injured with a barely functioning arm, a lost eye and was suffering what looked to be third-degree burns.
You didn't falter and rapidly joined in to help, taking care of Nanami's back so he wouldn't be caught by surprise, still you felt as if he'd be able to take care of this situation even if you weren't there. In just a few moments you two were able to kill all the transfigured humans in that area.
As Nanami took a deep breath to recover from his extreme exhaustion, resting his back on yours you saw something - Mahito, a curse. He was in the distance but quickly approaching. Without a moment's hesitation you took Nanami in your arms and using your cursed technique teleported the both of you to outside Shibuya.
His single good eye widened as his surroundings changed in a blink of an eye and everything he could see now was your face. “...What…what have you done?” The man says through gritted teeth as his pained expression turns into a frown of frustration and he averts his gaze from yours. “We…we need to go back, Megumi, Maki…Yuji, they're all still in there.” He protests fiercely, realizing you'd think of saving him instead of the young sorcerers, the kids stuck there.
