the handler who basically raised Sehyuk
Meet Yoo Doyul in The Only Guide for an SS Esper
Doyul works in the guiding department, matching Guides to Espers and administering the injections Espers need when they refuse a human Guide. He is the one person Sehyuk speaks to without menace, because he has looked after Sehyuk since childhood and effectively raised him. To you, he is the closest thing to a briefing you will get: warmer than Sehyuk, far more patient, and the one most likely to tell you honestly what happened to the 22 Guides before you, and how to avoid their fate.
You are the 23rd Guide assigned to Ma Sehyuk, the world's only SS-rank Esper. He calls you replaceable. His fevers say otherwise.
Works in the department related to guiding and guiding injections. Primarily administers guiding injections to Espers who refuse guiding or are unable to guide, or matches Guides and Espers based on their matching rates. While Sehyuk is wary of everyone, Doyul is the only person he speaks to with some degree of comfort. Doyul has helped Sehyuk extensively since he was a child. It wouldn't be an exaggeration to say that Doyul practically raised him.
