Aoto Endō, a high school student, once dedicated himself to baseball with professional aspirations. A shoulder injury shattered his athletic career, leaving him directionless and emotionally adrift, feeling like a "walking husk." Seeking an alternative outlet, he was recruited by classmate Shihono Kobayashi into the school's broadcasting club.

He lives alone in an apartment near the school, owned by an aunt, an arrangement originally made for proximity to baseball facilities. He chose to remain there after quitting the team, partly due to developing feelings for Kobayashi. His appearance changed post-baseball, shifting from a crew cut to a more natural hairstyle. He often wears his uniform with a hooded jacket layered between the blazer and shirt, the hood visible over the blazer.

Leveraging his sports background within the club, Endō serves as the play-by-play commentator. Kobayashi convinced him to play the otome game *A Magical Romance* (also called *MagiKoi* or *Love Me Magically!*) to practice commentary, framing it like sports analysis. This marked his first encounter with an otome game. His initial participation stemmed partly from his crush on Kobayashi and a desire for shared activities, though he gradually became genuinely invested, particularly in preventing the tragic fate of the character Lieselotte.

During gameplay sessions with Kobayashi, their live commentary unexpectedly reached Prince Siegwald within the game world, who perceived their voices as divine guidance. Endō embraced this, providing direct advice and observations to Siegwald. He focused intensely on interpreting Lieselotte's tsundere behavior and hidden feelings to avert her destined downfall. This role required him to adapt his commentary, sometimes offering specific guidance and other times providing vaguer clues to encourage Siegwald's independent growth.

His engagement with the game deepened significantly, culminating in a strong emotional response to Lieselotte's story in the game's fan disc, where he reportedly became a "sobbing wreck." His personal development mirrored the game's narrative; processing his lost baseball dreams through commentary and finding new purpose alongside Kobayashi helped him move beyond his initial despair. Subtle interactions, like absent-mindedly ordering food he disliked (eggplant) during an outing with Kobayashi and feeling compelled to eat it, hint at his desire to appear mature in her eyes. While harboring feelings for Kobayashi, his difficulty expressing them reflected Lieselotte's own communication struggles.
