Abstract

The best assassin was killed by the organization he used to work for right before his retirement.
A goddess in another world summons him, asking him to help with the murder of the hero.
He gets reincarnated as the eldest son of the assassin aristocrat Tuatha De with the blessings from the goddess. As long as he has his skill, experience, knowledge of the previous life, and the secret technique, magic that he acquires this life, he will no doubt become the greatest assassin and kill the hero.
