I was the last demon king, the strongest and greatest creature in the demon world.Iâm the best.âŚI mean, until I die after being betrayed and killed by the humans who served me.âWhen youâre born again, youâll have to do good things. If you donât want to live a worse life than a small creature.âTo break the curse I received before I die, I must do good deeds!The goal is to regain money, power, and fame, and live a life that takes a lot of benefits.Even if the body that entered at the best was a human kid, the ugly duckling of the family.This genius and cuteness! And there is nothing that canât be solved with this beauty(?)In order to grow into such a great Demon King, I work hard every dayâ.âI donât fall for cute things. No matter how much you wear a lace dress and tilt your head with cookies in both hands.âââŚyou were hiding your true skills. A clever thing.ââHey, you! They said you brought another boy! Do you think he can be your new brother?!ââOh, for your information, even just now, my soul and body were almost separated by the shock because the Lady was cute. Itâs inevitable because youâre very cute.ââYou know. Youâre the only one for me, Esther.âThereâs something wrong with the people around me.No, thereâs really something strange about it.
