The only thing that bothers me in this is the Idol thingy, really makes no sense in this setting. I wish the MC would debut from that and the author just act like it was something from the past to never be mentioned again.
In the webnovel Bond says when he was sealed away, he used to stream videos until the network went down, so idols are probably a remnant of a past era.

To be fair, karan, sem and tianna are typical jrpg, specifically dragon quest with a bit of final fantasy, stereotypes, while nick is basically a typical isekai'd person in isekai stories.
I can definitely see them saving the world, if only for how absurd some rpg parties can be, with bond being your typical talking sword from most stories, mainly, a character with querks that leads the party along a path.
