In this life, I will never live as a hero! Retirement, maybe! “A hero should remain heroic until the end.” Adelia, a knight who dedicated her life to the empire and died as a hero. But when she opened her eyes… ‘Nine years old? Me?!’ She was back in her childhood! Back to when her family was still alive before the fall of their house! Alright, this is a chance given by the gods. This time, I will save everyone and enjoy perfect retirement in a quiet place! But then… ”Sister!!!” Not only did she awaken the holy sword that had been asleep in the temple for 600 years, “Does the lady prefer tall men?” “…What?” The Crown Prince, who was her superior in her previous life, is showing interest in her? What is happening! I just want to retire quietly!
