I'm rating this as a supplementary experience to what is Honkai Impact 3rd as a whole, rather than as it is own thing, just like I did with the Anti-Entropy VN

Really enjoyed to see how Bianka was on her younger years and what did led her to become who she is later known in the timeline as Durandal, and how Rita did become an important part of her life, as well she did for Rita's life. It was also really interesting to see more of the Imaginary Tree/Sea of Quanta on this VN.

At last, while we didn't see this in the VN, Durandal and Rita definitely had a good time in bed
