The second Dimension Wave novel goes in completely different direction from the first, right into solo base-building territory. The main problem with this being that it doesn’t make any sense at all for a single person to get transported to the island instead of their whole party, especially in what’s supposed to be an MMO, let alone be indefinitely trapped there and completely isolated from the outside. Probably going to drop it here.
Kaketa Tsuki no Mercedes has a misleading English subtitle (The Dungeoneering Feats of a Discarded Vampire Aristocrat, the Japanese subtitle is perfectly on-point though) considering that she’s never discarded. Quite the opposite. It’s the variety of overpowered protagonist series where due to certain circumstances they don’t actually realize how overpowered they are, and in general mood it reminds me a bit of Moto Ansatsusha, Tensei shita Kizoku no Reijou ni Narimashita minus the romance elements.
