Here's an epub you can download! It will let you read offline
Book 1: https://z-lib.io/book/16767827
Book 2: https://z-lib.io/book/17416432
You can also buy both volumes on amazon or at barnes and noble if you want the physical copies
they are in low supply as the publishing house (Peach Flower House) closed down and aren't printing anymore so they might be a bit harder to get now :(
Oh that's sad :( you're right, they're unavailable on amazon right now. Hopefully another publisher picks it up
you can vote here for seven seas to pick up the novel and comics to translate into English and put it out in paperback:
