Lux, a former prince of an empire named Arcadia that was overthrown via a rebellion five years earlier, accidentally trespasses in a female dormitory's bathing area, sees the kingdom's new princess Lisesharte naked, incurring her wrath. Lisesharte then challenges Lux to a Drag-Ride duel. Drag-Rides are ancient armored mechanical weapons that have been excavated from ruins all around the world. Lux used to be called the strongest Drag-Knight, but now he's known as the "undefeated weakest" Drag-Knight because he will absolutely not attack in battle. After his duel with Lisesharte, Lux ends up attending the female-only academy that trains royals to be Drag-Knights.

First few chapters are carbon copies of IS and a few other manga. Seemingly weak protag offends the school beauty due to a misunderstanding and has to duel her. Then the story turns a little bit in a more interesting direction, but I still have a few concerns about the lore and characters. It;s been 15 chapters and I still don't know, if I'm interested in following this story or not. For now I like the art more than the story.

Stereotypical badass male in an all-girls school who builds a harem.

Whats there to say? Quite literally the story has retconned its own backstory no less than 3 times in the 9 chapters that have been translated. The characters are so shallow that the hotheaded princess falls in love with the main protagonist before the end of chapter 2.

To top it all off the world is so shallow that empires literally don't get names. The current ruling empire's name where the story takes place? The "New Empire". The previous ruling empire's name? The "Old Empire".

All i gotta say so far is this is just a generic harem manga again. Starts with a seemingly weak but special main lead who encounters the strong yet somewhat bitchy tsundere heroine, they fight at first and yada yada all or majority girls academy yada yada yada....yea seen this situation a bunch of times and its getting annoying. Also this is almost exactly the same as Infinite Stratos, especially the armor designs..... i keep checked on this and i hope it strays away from the generic harem manga but i doubt it

Just read the first 3 chapters, the same setting from other "I'm a wuss that gets in an H awkward and really absurd situation but I'm just strong in my own way and I'm ready for a harem" kind of manga. Well, at least it is entertaining as all of the previous ones. I'm honestly getting tired of reading the same setting just with different drawing techniques, characters and situations.
