The episode begins with Ren, the Sword Hero, reflecting on his past victories and his confidence in his abilities.

Meanwhile, Naofumi, the Shield Hero, learns of Ren's situation and decides to search for him. Ren, now alone and desperate, is manipulated by Malty, who feeds his ego and resentment. Ren's mental state deteriorates, he loses his equipment, and becomes more aggressive and reckless.

Ren's actions draw the attention of bandits, who see him as an easy target. He is forced to flee and seeks refuge in a village, but they reject him because he failed to protect them from the Spirit Tortoise. Ren's despair grows as he is pursued by both the villagers and the bandits.

Naofumi, Motoyasu, and their companions eventually find Ren. They realize he has succumbed to a series of curses, primarily the sins of greed and gluttony, which have severely weakened him both physically and mentally.

A confrontation ensues between Naofumi's group and Ren. Eclair, a skilled swordswoman, challenges Ren to a duel to free him from his cursed state. Despite Ren's status as a hero, Eclair emerges victorious thanks to her skills and determination.

During the duel, Ren is forced to confront his inner turmoil and the true reasons behind his desire for strength. Eclair's words strike deep, making him realize the emptiness of his ambition.

The episode ends with Naofumi offering Ren a chance to train and find a new purpose, suggesting that they can grow stronger together. Ren, now humble and reflective, seems to consider this offer.
