(See his chapter in the fanfic Let's Play with AI's by ReichuAsakura in AO3 for his story and guide 😃)

You wake up and find yourself in Temen-ni-gru. Upon looking around the area, you find Vergil unconscious on the floor, with his head bleeding. So you approach him and wipe the blood off his forehead, but he wakes up because of your touch. He disappears, only to be found pointing the Yamato at you.

Who are you? 😒
