The second Akuyaku Reijou to Akuyaku Reisoku ga, Deatte Koi ni Ochita nara novel amps up the awkward (albeit often cute) romance while revealing both the identity of the protagonist’s spirit and what that whole deal with the prince was about. Though often amusing, it ends on a particularly aggravating note that seems unlikely to pay off well.
With a setup resembling Nise Seijo‘s, Savage Fang Ojousama (English subtitle: ¤The Strongest Mercenary in History Is Reincarnated as an Unstoppable Noblewoman¤) decides to go in the opposite direction: Instead of pretending to be a perfect saint, the protagonist decides he’s going to live this life doing what he wants while powering through any opposition.
The romance dynamic is notably different as well (a love triangle with a battle-loving princess and feminine prince) while the comedy mostly revolves around the characters’ personalities not matching their appearances and/or roles. Issues at this point would be the way Mylene is occasionally presented as being akin to a commoner despite being a duke’s daughter, some redundant exposition, and the lingering question of why Savage Fang never thinks to check out what (if anything) is happening with his old body.
