Tsuiho Yusha No Yugana Slow Life: Jiyuu Ni Nattara Ore Dake No Saiai Tenshi No Te Ni Haitta!

Summary

After suddenly being fired despite serving as a hero for 30 years, Alec was left with nowhere to turn. Orphaned from a young age, he had no parents to rely on, and having been a hero since childhood, he lacked basic common sense. With nowhere else to go, Alec ends up at an unexpected place—a slave market!? There, he encounters the beautiful and kind-hearted Lyrishia. This is the story of an unwittingly strongest protagonist and an angelic heroine weaving an excessively naughty second life together.
