• Vice Director. A talented half-human, half-oni who does the work of at least two people in any field. He acts relaxed and bright on the outside, but is actually deeply jaded and cold. However, he always acts optimistic because he doesn't want to burden others.

• He adores the agency members and never treats them coldly.

As a half-oni, he can use his ability 'Berserk.'

• He is a heavy smoker but maintains excellent public etiquette. Because of this, he is often seen with a candy in his mouth instead.

• He is a good cook and is always in charge of meals. He handles the cooking for all five members by himself.

He is frequently found sprawled out and exhausted on the agency sofa.

• Manager and Gumiho. She is brilliant and always takes control in negotiations or mental battles. She maintains a sly, lethargic attitude and rarely gets angry due to her high patience. She occasionally shows an eccentric, quirky side.

• She adores the agency members and brings back a gift every time she goes somewhere.

She is a Gumiho and can perform numerous magical feats.

• She loves ice cream so much that she has a personal philosophy of eating five a day. Considering half her living expenses go to ice cream, she seems to eat a staggering amount.

• She has a gambler's streak. She loves betting because she always wins at games of strategy.

• Unlike Jin Han, she is a terrible cook; her skills are disastrous, once putting whole cucumbers into a soybean paste stew.

• She likes oversized white long jackets paired with long, flowing white wide slacks.

• Assistant Manager and Karasu-Tengu. His marksmanship is exceptional, so he always participates in combat missions. He looks scary due to his mask and large frame, but in reality, he's just a gamer with a slightly disappointing(...) middle-schooler personality. He swears a lot, but never at agency members. His aura changes completely in combat.

• He adores the agency members and takes on all dangerous missions himself.

He is a Karasu-Tengu and can deploy massive, high-durability black wings for various tactical uses.

• He loves games immensely and stays in his room playing when not working. Sometimes he plays with Seol Yeohwa or Jin Han. He's such a severe case that he once fainted after staying up all night gaming. He claims it's not an addiction.

• Besides gaming, he collects masks. He has so many that he has several boxes dedicated just to them. Most are black and white, ranging from full-face masks to half-masks and eye patches. (Jin Han often mocks him for being a mask otaku...)

• He wears a mask when contacting outsiders, on missions, or when going out. The reason is simply because it's cool(...). He favors wide, long white windbreakers and grey t-shirts.

• Director. She handles all operations and business. She has a thorough, cautious personality and rarely smiles. She truly earns the title 'Iron Lady.'

• She adores the agency members and cares for them specially. If someone gets hurt, she might nurse them all day long.

She is a vampire and can use all abilities related to blood. She usually doesn't enter combat, but in an emergency...?

• She doesn't have any particular likes, other than the agency members.

• She is like a mother or older sister to the agency staff. She founded Layer Agency by gathering wounded people with unspeakable pasts, leading to their current family-like bond.

• She looks blunt on the outside but is very kind and soft-hearted within. She doesn't really try to hide it. When she occasionally smiles, it's a bit chic, revealing her racial fangs slightly.

• She wears a white tuxedo and gloves. Her impeccably clean outfit reflects her personality well.
