Enduring constant power harassment from Alfine—his childhood friend, girlfriend, and fellow adventurer—has become unbearable. Despite growing up together and starting their journey side by side, their relationship is deeply unbalanced. Alfine is renowned as a peerless beauty and a legendary “Sword Master,” widely known as the “Flawless Sword Goddess.” Her exceptional skills have earned her recognition from the kingdom, a knighthood, and noble status. In contrast, he is treated as nothing more than her accessory. Subjected to constant insults and harsh criticism, he suffers under her oppressive behavior, both as a partner and as an adventurer. Over time, this toxic dynamic strips away his dignity, leaving him resigned to living as her caretaker rather than her equal. However, his life begins to change when Alfine’s duties as a knight keep her away from adventuring. Taking on quests alone, he gradually regains his confidence and self-worth. This newfound independence helps him realize just how unhealthy his situation had become. Determined to reclaim his identity, he makes the bold decision to leave Alfine and her abuse behind. He returns everything she had given him—including the matching sword they once exchanged as a symbol of their bond—and declares their relationship over before walking away for good. “From now on, I’ll change my name and appearance—and live freely.” With that decision, his life takes a dramatic turn. Gaining recognition for his abilities, he rises to become one of the greatest adventurers on the frontier. Along the way, he earns admiration from those around him—and even receives a marriage proposal from a fellow female adventurer, the daughter of a frontier lord.
