Now that I can finally retire and rest, what?! ‘Seven years old? I?!' The continent's first female knight, Adelia, spent her entire life wandering around the battlefield until her death. And she was back when she was seven again. “There is an academy entrance ceremony tomorrow, young lady. If you don’t finish packing your bags….” "……Academy?" Before Adelia could even adjust to the fact that she had returned, the maid Sarah placed her luggage in front of Adelia. Oh, I did. That academy raised Adelia into her knight, made her a knight of the Holy Sword and a hero of the empire, and ultimately drove her to her death. But you want me to go back to the academy? 'No problem.' Adelia said, looking as if she was about to tear open her luggage. "Sera." “Yes, miss.” “This baggage…unpack it all again.” "yes?" Adelia's cold voice continued. “No. …just burn it down.” *** Adelia decided to consider this opportunity as a well-deserved vacation given to her by God. however. [Nuniiiiim~~!!!] It's not enough that the Holy Sword, which shares memories of the past, has returned together. 'what's this! … … 'You're an Auror?!' Even the aura appeared earlier than expected. Why are you doing this? I told you I’m retired! I will never live as a hero in this life! Even if it’s retirement!
