縁の下のチカラモチャー ～魔王討伐したら若返ったので、学園で陰からサポートします～
Sakuya aimed to operate in the background as a support hero. After nearly defeating the Demon King alone, he was restored to youth. Seeking a new purpose, he enrolled at an academy that trained aspiring adventurers. There, he met Fuyuna, the school’s top swordsman. Observing her desire to compete with other academies, he joined the institution as a minor member to assist her discreetly. Despite his strength, he avoided drawing attention by keeping his abilities hidden.
