Isekai Hoikuen wo Hirakimashita: Fusei Skill de Saikyou Loli Seirei-tachi wa Deredere desu

Oliver is a seasoned adventurer nearing his forties who has spent years navigating the perils of his profession. Known for his earnest and dependable personality, he is the kind of man others trust without hesitation. It is precisely this unwavering sincerity that leads to him being entrusted with an unexpected and highly unusual mission—one that will completely alter the trajectory of his life. Rather than slaying monsters or exploring treacherous dungeons, Oliver’s new assignment requires him to form binding contracts with a group of immensely powerful yet overwhelmingly affectionate little spirits. These young entities possess extraordinary abilities, but they are equally defined by their deeply endearing and doting nature toward him. Bound together by this unique arrangement, the spirits gradually gather around him, transforming his solitary adventuring days into something entirely unforeseen. With his newfound companions by his side, Oliver steps away from the front lines of adventure to embrace a completely different calling. He assumes the role of a school principal, dedicating himself to guiding and nurturing these remarkable beings. What begins as a simple contract blossoms into a heartwarming new chapter, as Oliver builds a vibrant educational haven where his extraordinary skills as a caretaker shine brighter than any sword.
