If you're putting this off because of the ecchi/harem tags and the oversized boobs Don't. I'ma be real, the ecchi is not for the fainthearted, there's lots of it, it's pretty much borderline hentai. On the other hand the harem is actually more like a poly relationship than a harem, and as for the boobs. The Oversized and Gratuitous, Boobtastic Titties! As much as they're a visual gag they actually serve as character development as well. This actually a pretty heartwarming comedy with decent slices of plot, fun character interactions and a cool MC. This is a decent read and you've probably read worse.
Tldr: Bottom line the fact that you're here considering this manga probably means you've probably read real trash isekai and this is much better.
Gabi is so annoying she acts like she isn't being trained to become the armor titan and do the same thing using titan powers for their own self gain and she keeps calling them devils like she doesn't have the same exact blood flowing through her too
Yeah because the author focused to unravel the story from the MC sides, bit by bit the bitch heroine regaining her memories of the truth of the real pedo killer, and the main Villain acting like a swindler and a psycho in internet change to a proactive murder like boy A(even thought we don't know the heroine saves or died by blood loss). If the reader only read from the perspective from the MC only the story line will be boring, weak and cliche🤔 but if you keep reading until the lattest chapters you will know the author makes this manga so awesome
