Synopsis Taidana Akuyaku Kizoku no Ore ni, Konyaku Hakisareta Akuyaku Reijo ga Totsuidara Saikyo no Fufu ni Narimashita

Alban realized he had been reincarnated as the villainous noble in a certain novel. Just as he began training in swordsmanship and magic to avoid defeat by the protagonist, he learned that Leticia, a noblewoman surrounded by nasty rumors, was to become his wife!

He was nervous about what kind of “evil woman” she might be… but, upon meeting her, he found an incredibly pure girl — angelic, and exactly his type! Alban, forgetting all about avoiding his doom due to her adorableness, resolved to take revenge on the mastermind who had set up his beloved wife!

Using their villainous reputation to their advantage, they set out to lure the culprit, but… will they succeed?
