Shtulls had fought a bloody war for the human kingdom despite not being a human himself. He watched his men die and struggled on until he beat the demonic emperor and returned home a hero.

But on the eve of his medal ceremony, he encountered a being that changed his life for the worse.

Now he's cursed, poor, homeless and without mana.

His curse forces him to say or do whatever he thinks is the worst thing possible and has robbed him of his honor and dignity often in hilarious ways.

But in this standard videogame like world there must still be hope for the fallen hero and perhaps that hope comes in the form of a half-succubus paladin.
