Aden Albireo, the \"Dragon Slayer King\", was a hero who saved the world by eliminating the Berserker and the Underlord. However, he was betrayed by those who whispered friendship to him, and met his death...
\"I didn\'t know I would be resurrected like this?!\"
15 years before the Underlord\'s resurrection, \'Aden Albireo\' reincarnated into the body of the eldest son of a unheard-of duke\'s family, \'Aden Remes\'! And...
\"It\'s been a while, Dragon Slayer King!\"
\"The Underlord I thought I had defeated is inside my soul?!\"
Will Aden be able to end his uncomfortable cohabitation(?) with the Underlord and prevent his resurrection?
