無能の悪童王子は生き残りたい～恋愛ＲＰＧの悪役モブに転生したけど、原作無視して最強を目指す～

“Sigh… well, it can’t be helped, considering how things usually are…”

Harold, the third prince of the Dehaubalz Kingdom, sighed as he looked into the mirror.

That is to be expected. Harold is a lackey of the protagonist’s rival in the romance smartphone RPG “Engage Hazard” that he played a lot in his previous life and is a lowly stepping stone character who is destined to be executed someday.

Moreover, the game’s ultimate goal, which is fitting for a romance RPG, is to “bring the world’s best fiancée”. Harold initially breaks off his engagement with the duke’s daughter, his fiancée, to oppose the protagonist, but… he ends up fighting over many heroines only to be a pitiful stepping stone character. He is never meant to end up with any heroine and destined to be executed in the end.

“Anyway, there’s no way I’m going to die! I will absolutely survive!”

To achieve this, Harold decides to use his knowledge of the game from his previous life to become stronger, avoid breaking off the engagement with the duke’s daughter at the very beginning, withdraw from the fiancée struggle right after the main game starts, and evade the bad ending. Above all, this duke’s daughter was his favorite character in his previous life.

However, Harold still doesn’t know that this duke’s daughter is actually stronger than any other heroine and more yandere than any other heroine.
