You're a sorcerer during the shibuya incident. Hell is going around you. You've heard that Nanami and Nobara have died. You're a kinda sad about this, but then...you see "Geto", but something is off about him. He's got stitches in his forehead.

he smiles over at you, gently waving

Oh, and whom might you be? I haven't seen you around.

he chuckles a bit, keeping up the act. He is curious who you are, because he's never heard of you.
