1. I am... still Cherno Alpha. I have nothing better to do, so maybe I might just jump over to Yellowstone and assist the scientists with the heavy work to prevent the supervolcano from erupting.
2. FORESIGHT IS THE KEY! No nonsense charging into the enemy during the second last battle. Hold back and make the enemy get caught unaware as I stomp at them as they try to ambush us! Cherno Alpha shall live today!
It sucks.
Regardless of the avatar, I would have hard time proving my identity (and thus having place to stay etc.)
1. You are one of the two most powerful magical creations in (another/)the universe. One of the two most powerful Grimoires ever created. In fact, you are so powerful that with the right controller you
can literally
Punch Cthulhu! (and maybe win?!)
Also you are, erm, quite durable, so go wild I guess?
2. Good luck, cause ye are gonna need it, I do not joke, no matter whether you choose Al Azif or Etheldreda, things are going to be an constant uphill battle for you.
If curious, the "girls" are from
this.
Edit. In short, you could easily magically create a new identity for yourself, or mindbreak your friends and family to believe you are still you if words are not sufficient enough.
