Isekai give me mixed feelings, eh. But Jack does seem like that kind of character based on the trailer, the end part with the...phone? His clothing didn't quite fit that kind of period that everyone else was in. Gave more more modern fantasy (XV) feels. And the big emphasis on being a Stranger!
No plans on getting or playing the game, unfortunately. I don't really have much time to play games lately. The last time was neo the world ends with you back in July. I can't wait to see the story though!
