Adjusting to life in new world (is Tos’ world just Latvia?) can be interesting on it’s own. See: Konosuba.
I never played RO (which seems to be where David is from) but I’d imagine it’d be funny to see people’s reactions to him using skills from his home world.
Maybe his motivation comes from something he heard as he passed on? What if the goddess he’s trying to save is actually Ghesti, who was sealed inside of the tree by the Revelator Train (if we assume the story takes place post-MMO)?
I think when you die ingame you just kind of reappear at the nearest teleport statue or where you entered the map, I don’t really remember either
