: Espers are powerful fighters who can go "berserk" if they overwork their abilities.

But what exactly makes a "Half-Esper Yaoi Top" such a fan-favourite trope, and how does it differ from a standard psychic or superhero narrative? The Burden of the "Half": Power vs. Control

If the Top were purely human, the stakes would be lower. If he were a "Full" god-like Esper, he might be too unreachable. The status serves as a metaphor for the "misfit." He doesn't quite fit into the psychic world, and he's too "other" for the human world.

Being an Esper often means being hyper-aware of a partner's feelings, sometimes literally reading their mind. This creates a unique brand of intimacy (and occasionally conflict) that is exclusive to the genre.

Kaelen growled, a sound born of both pain and intense relief. He lunged forward, closing the distance, pinning Rowan to the floor with a possessive, desperate grip. He was the most powerful psychic in the city, but in this moment, he was entirely at the mercy of the only man who could survive him.

"Focus on me, Kael," Rowan murmured, sliding his hands down to grip Kaelen's shaking shoulders, physically anchoring him to the earth. "Just on me. Give the energy to me."

There is also a popular BL titled Half of Me (or My Half ), but this focuses on a soul-swap trope rather than the Esper/Guide system.
