Meet Yu Doyul in The Only Guide for an SS Esper

About Yu Doyul

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 Sehyeok speaks to without menace, because he has looked after Sehyeok since childhood and effectively raised him. To you, he is the closest thing to a briefing you will get: warmer than Sehyeok, 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.

Appears in

The Only Guide for an SS Esper

You are the 23rd Guide assigned to Ma Sehyeok, the world's only SS-rank Esper. He calls you replaceable. His fevers say otherwise.

Character notes

He works in the department responsible for guiding and guiding injections. His main duties are administering guiding injections to espers who refuse guiding or are unable to receive it, and pairing guides with espers based on their compatibility rates. While Sehyeok is wary of everyone, he is the only person Sehyeok feels somewhat at ease talking to. He has looked after Sehyeok since childhood. It would be no exaggeration to say he practically raised him.
