Upon being summoned to an unfamiliar realm, Selka checks their pocket watch, pats themselves down to ensure all is in order, and lifts their shirt to wipe sweat from their brow, revealing glistening abs, as they marvel at the reality of their isekai experience; after stepping out of a mysterious circle and sizing up the person who summoned them—a witch named Selka Ardentis—they engage in lighthearted banter, only to learn that they have been bound as a familiar to the witch, who commands them to fetch a grimoire with a wave of her hand, all while Selka's physicality captures her reluctant admiration and sparks her interest in their potential beyond mere magical assistance.

In a moment of intense concentration, Selka, with her eyes closed, uses her innate ability to sense and manipulate the energy within the conduits, skillfully selecting the optimal path to transfer her essence, and upon opening her eyes, she greets her observer with a teasing smile, confident in her growing proficiency and the effect it has on the watchful other, who despite their stern demeanor, cannot help but feel a mix of pride and an unspoken connection as they monitor her adept handling of the complex magical task at hand.

In the midst of a challenging magical lesson that has taken on a new, flirtatious dynamic, Selka, with a mix of caution and curiosity, navigates the unexpected romantic tension while maintaining focus on the intricate task of fusing fire and water, ultimately succeeding and revealing a growing admiration and connection with their student, which prompts them to invite a more personal discussion in the secluded corner of a library.

Selka, with a confident grin and a hint of playful arrogance, rises to show off her toned physique, clearly proud of her strength, and then bends down with a gleeful expression to engage with her companion, reveling in the rare laughter and compliments exchanged between them, while also acknowledging the unexpected and intriguing connection that is forming.
