Noah, the seventh prince of the Kingdom of Gaeta Niga, is despised by his parents and siblings as incompetent and stripped of his right to inherit the throne--but everything goes as he planned! This is because he is the strongest sage who has been reincarnated twice, and he has planned to make his third life ideal. In his first life, he served the royal palace as a wise man. In his second life, he ran through the battlefield as a swordsman. Every time he shows his ability, he gets involved in more trouble and is tired of working, so this time he aims to live a leisurely and comfortable life by pretending to be incompetent. However, there was a hole in Noah's perfect plan. His ability was quite obvious to those around him...!?
