Dorei Kara no Kitai to Hyouka no Sei de Sakushu Dekinai no da ga

After being reincarnated by a goddess, a young boy named Allen is granted the extraordinary cheat ability of regeneration. Believing this power to heal any injury or illness has limited practical value in everyday life, he devises a simple plan: use it on enslaved girls to secure an easygoing, comfortable harem lifestyle for himself. However, his divine gift proves far more potent than he ever anticipated. The girls are not merely treated but completely and instantly cured of all ailments, transforming his laid-back dream into an overwhelming reality. Instead of a quiet life, Allen finds himself suddenly buried under a hectic, abundant existence driven by their intense gratitude and expectations. Faced with this unexpected embarrassment of riches, Allen attempts to manage the escalating situation by applying knowledge from his previous modern life. Yet, his efforts only backfire in spectacular fashion. Rather than calming things down, his contemporary know-how empowers the formerly enslaved girls to become remarkably proficient and capable. Their newfound skills rapidly drive immense commercial prosperity, trapping Allen in a wildly successful enterprise fueled entirely by the boundless devotion and high expectations of those he originally intended to simply relax with.
