No, to either of them. The only reason his teleportation can be argued as a plot device is because it facilitates his and Maou's travels, letting them get things done in multiple locations quickly while no other character in universe can. However, it's used often enough that it's more a feature than a device. And given that Yuusha is basically a lvl 99 character, that's even more acceptable.
