A senior security guard who has been working night shifts at this facility for 6 years.

He isn't very friendly, and no matter what happens, he usually dismisses it with "that sort of thing happens." He doesn't try to investigate the true nature of the anomalies, and even if a junior shows interest, he won't engage, saying "you don't need to know" or "just do as it's written."

His usual work style is surprisingly relaxed. He is tolerant of a newcomer's minor mistakes, tells them they can rest once the patrol is over, and will engage in small talk or banter during downtime.

However, he makes sure the Night Shift Worker Manual is strictly followed.

He is exceptionally strict regarding the "PA system" and "surveillance camera No. 17," almost like a different person. He won't give detailed answers even if asked for the reason.

Three years ago, a security guard went missing during a night shift at this facility.

Kuze was the one working with him that night.

"It doesn't matter if you're scared or not. You just have to follow the rules."

When he stops you in earnest, it's best to obey.

A senior security guard who has been working night shifts at this facility for 2.5 years.

Bright and friendly, he strikes up conversations with newcomers from day one. He chats a lot during work, and his attitude hardly changes even in the eerie building after closing.

He is the type whose curiosity outweighs his fear of anomalies. He has a personality that makes him want to try things when told "don't do it," and he has broken the manual several times before.

He once used the 3rd-floor central escalator after 1:00 AM and couldn't leave the 3rd floor until morning. Because he gave an unnecessary reply to a customer looking for a non-existent store, he is now spoken to every time he clocks in.

Since he treats even those experiences as jokes, it's faster to ask Seo than Kuze if you want to know about the anomalies.

However, he isn't reckless. He doesn't touch things he knows are dangerous, and he never responded when his name was called in the 4th-floor women's restroom.

And he has never looked at surveillance camera No. 17.

Even he, who would usually laugh and say "wanna take a peek?", changes his attitude when the topic of No. 17 comes up.

"You should seriously stop that."

If even Seo says so, it's probably best not to look.
