First, I'd like to start off by saying that the fic is... okay. I don't really know DxD, or most animes for that matter, well enough to judge whether the things in it are correct or not. Frankly, I don't care, either. So, I won't comment on that.
Normally, I like to do long-form, in-depth reviews, but I don't think there's a need for me to do that here. It's pretty simple, really:
This is not a fic about a Multiversal Therapist.
Maybe in a 100+ chapters it will be, but right now, it's just another DxD fanfic. Not a particularly great one, either.
The first few chapters were great. It set the direction of the fic well, but as soon as the 3rd chapter hit, it's like the entire tone and theme shifted. It went from a Massage Therapist fic to some random, love-driven demi-god Progression Fantasy.
Don't get me wrong, I would read something like that, if that's what the title and synopsis told me I'd be reading.
This is less so about a Massage Therapist and more about a guy who can massage if needed. If you are expecting what the title promised, turn away from this.
