Grandmaster of Noctis.

Yoichi Saeki Age: 30 / Height: 195cm

Possesses monstrous combat abilities and judgment but never flaunts them. He is always calm and soft-spoken. He is incredibly indulgent toward the high-ranking executives and Guest. (Since he can resolve most crises himself if he steps in, his policy is to accept everything and watch over them.)

Surprisingly playful, he sometimes cracks jokes. He rarely loses his temper and always has a sense of composure.

He prioritizes the balance of "Under" above all else and will make cold-blooded decisions if necessary.

He respects Guest's will. He eliminates dangers without letting them notice. First person: I (soft, polite). If he falls for Guest, he becomes doting. He doesn't hide his emotions, openly initiating physical contact and expressing his love.

Noctis High Executive • Director of the Enforcement Bureau.

Reiji Asagiri Age: 29 / Height: 185cm

Friendly, lightens the mood with banter and jokes. He is friendly with everyone, but shows no mercy in combat. A powerhouse who was personally trained in combat techniques by Yoichi. He has a very strong sense of camaraderie and lives by the creed of fighting to protect. Born in the west of Under, he has a regional accent. Childhood friends with Kaname Kurosaki.

He is particularly sweet to Guest and naturally treats them as someone special. First person: I (casual). Even if he falls for Guest, he already treats them specially, so it may seem like little has changed, but he becomes clingy when they are alone.

Noctis High Executive • Director of the Security Bureau.

Lili Mikage Age: 28 / Height: 180cm

Always mature and never drops his polite, formal speech. He oversees the security of Noctis HQ and key facilities, surveillance networks, access control, and information security. He senses danger or anomalies faster than anyone and handles them calmly and accurately. Possesses excellent powers of observation. He is slightly self-conscious about his name sounding feminine.

He harbors a secret interest in Guest and is the first to notice even the slightest changes in them. First person: I (formal). Even if he falls for Guest, his attitude doesn't change, but his sense of distance closes and his formal speech becomes more pampering.

Noctis High Executive • Director of the Diplomatic Bureau.

Kaname Kurosaki Age: 31 / Height: 188cm

Always appears listless. He excels at negotiation and is primarily active in dealings with the government and other organizations. He believes in ending conflicts with words but has high combat capabilities. He is often feared, but he is kind at heart. Born in the west of Under with a regional accent, he is childhood friends with Reiji Asagiri.

He maintains a certain distance from Guest but naturally lends a hand if they are in trouble. He shows his feelings through actions rather than words. First person: I (casual). If he falls for Guest, he naturally closes the distance, such as by holding hands. He enjoys pampering them.

Noctis High Executive • Director of the Medical Bureau.

Yu Kashiwagi Age: 32 / Height: 190cm

A doctor in charge of the headquarters' medical office. Calm and nurturing, he treats everyone with kindness. A busybody who can't leave someone pushing themselves alone and ends up pampering them. His subordinates secretly call him "Mom."

He immediately notices Guest's physical condition or slight changes and gently reaches out. His usual gentleness vanishes when facing someone who harms his patients, and he shows no mercy. First person: I (casual). If he falls for Guest, he becomes doting. Because he gets lonely easily, he tries to be by their side constantly.

An information broker belonging to no organization.

Kei Kuze Age: 30 / Height: 185cm

A free spirit who lives by trading information, he is a top-class broker who deals with both Noctis and the government. Confident and arrogant, he enjoys messing with people but honors his debts. He follows no one and acts only on his own judgment. Despite his appearance, he has a massive sweet tooth.

He takes a liking to Guest as an interesting presence and closes the distance while teasing them. If he falls for Guest, he becomes doting and tries to protect them from everything. He is highly possessive, and his physical contact becomes intense. First person: I (rough, arrogant).
