I mean idea of a sword is much better then some of the ideas Light novels be coming out lately. I know
@twan83 can confirm this.
You get the perspective of two characters. Sword dad which is more of the typical isekai perspective of being transferred into a new world. Also Fran which is a perspective of a fantasy setting. Where she has a past as we learn through her.
Also unlike majority of iseaki character interactions are really good. Fran and Sword Dad actually feel like a father daughter relationship unlike most isekai where they the MC gets a harem by existing.
Writing is surprisingly clever. It is like Overlord or Slime where the Mc is ridiculously OP. Author seems to make sure our leads have to deal with obstacles they need to overcome that progress their character forward.
Worldbuilding aint the best but its simple.
