There was a Cute Girl in the Hero's Party, so I Tried Confessing to Her Episode 10: I Tried Hearing Out the Guardian Deity's Troubles

The episode opens with Kouzou, a young man, being woken by Gai, a formidable purple-skinned demon. Gai, weary of his idle life and the financial support from the kind Teal, declares his desire to work and become an adventurer. Kouzou, surprised but seeing Gai's genuine determination, agrees to help him, initiating a magical transformation. This scene establishes the unexpected depth of Gai's character, driven by gratitude and a desire for purpose.

Gai, now disguised in a fur-lined cloak, presents himself at the Adventurer's Guild, causing visible distress to the Guild Receptionist. The enigmatic Yuuki, known as the Black-Masked Swordsman, steps in, vouching for Gai and reassuring the bewildered staff. After some comedic bickering involving the Guild Master Cley-man and his lunch, Gai is registered as an F-rank adventurer, with Yuuki dramatically promising to guide him.

As they leave the guild, Yuuki proudly declares he will show Gai around the city of Minerva and be his guide. He warns Gai against using his dark magic, which would reveal his true demonic nature. Then, in a moment of theatrical flair, Yuuki proclaims Gai to be "the Black-Masked Swordsman's partner," only for Gai to flatly refuse the title.

Returning to the guild for a quest, Yuuki is informed by Cley-man that he has a visitor. This turns out to be Cecilia, a nun, who patiently waited for him and immediately sees through his Black-Masked Swordsman persona, identifying him as Yuuki. A flustered Yuuki attempts to deny it, but Cecilia explains that rumors reached her via Sophia, the maid, confirming his identity and leaving him defeated.

Cecilia quickly grasps that Yuuki's masked identity is meant to help Gai blend in, a motivation she approves of. Despite Yuuki's initial surprise and mild resistance, Cecilia declares she will cooperate, citing her concern for the Black-Masked Swordsman's solo endeavors. She then suggests they all start with beginner requests together.

Their first quest together is a pet search, and Yuuki immediately launches into a dramatic, overly enthusiastic performance. While Gai and the bewildered Townspeople look on, Cecilia calmly gathers the necessary information about the missing cat. Yuuki then uses his enhanced senses and super speed to locate not one, but two cats, resorting to a sleeping spell when they hiss at him. He dramatically reports his success, even healing an injured cat and urging the owners to care for both.

The party moves on to herb gathering, where Gai shows a quick understanding of the task, prompting Yuuki to laud his progress. Following this, their next quest is goblin extermination, which Gai handles with effortless power, dispatching multiple goblins with a single swing of his hammer. Yuuki and Cecilia are left stunned by his efficiency, with Yuuki comically attempting to take credit for Gai's strength.

Back at the guild, Cley-man hands Gai his reward money, which Gai accepts with visible joy and pride. He reflects on Teal's hard work and declares his renewed determination to earn his own living to repay her kindness. Despite Yuuki's insistence on supporting him, Gai politely but firmly states his desire to try working alone from now on, confident in his newfound understanding of quests.

Yuuki, now alone with Cecilia, flirts clumsily, suggesting they spend more time together. When Cecilia agrees, but points out the impracticality of her nun's habit for outdoor travel, she surprises Yuuki by quickly changing into a practical adventurer's outfit, complete with swirly glasses, introducing herself as "Adventurer Cecilia." Later, around a campfire in Yuuki's magically secured camp, Cecilia insists he remove his mask to eat. He complies, and their simple meal becomes a moment of shared warmth, with Yuuki lavishly praising her cooking.

As Cecilia rests, she dreams or reflects on a past struggle: a royal court scene where she, clearly a figure of importance, is pressured into a political marriage by a bored Prince and a serious Knight. She adamantly refuses the proposal, her face a mix of sadness and resolve, her inner thoughts revealing a deep conflict and a sense of being trapped. She repeats, "I will not marry," her quiet determination masking deep emotional turmoil. This internal struggle is framed by Yuuki's earlier, seemingly innocent, declaration that he will be the hero who saves her, creating an ironic contrast with her actual predicament.
