Two action adventure fantasy isekai manga with a lone adventurer meeting other people whilst travelling into places completely new for them (isekai).
They actually have enough competence, strength and skill not to be overpowered by monsters, but still decide to create social contact with the inhabitants to learn more about where they're in now.
