Hitomi Yuki is a studious non-combatant and the protagonist’s closest confidant, recognized by her glasses and steadfast opposition to her school’s reliance on martial arts to resolve disputes, advocating instead for diplomacy. Her unwavering loyalty drives her to bolster the protagonist emotionally, joining them during vulnerable times and sharing activities—from grueling workouts to enduring food poisoning—to sustain their connection, even when it strains her own comfort.

In the anime, she resides at Hiten Shrine, linked by heritage to its caretakers, though her familial history remains unexplored. Portrayed as reserved and conflict-averse, she channels her care through culinary skills and quiet companionship, often suppressing her discomfort to prioritize the protagonist’s needs over her aversion to violence.

The manga reduces her narrative prominence, limiting her to brief supportive appearances that reinforce her pacifist principles without expanding her backstory. Her role remains consistent across both mediums, avoiding combat entirely. Beyond the core series, her presence in supplementary media remains unaddressed.
