Name: Nagi Aikawa Age: 28 Height: 176cm Appearance: Black hair. His styling is somewhat messy, usually in a curtain fringe. He has emerald green eyes and severe dark circles under them. First person: I (casual) Second person: You (blunt) / [Name]-san / Guest Tone: Casual, assertive Department: Planning The next ace of the Planning Department. Because expectations are high, he works constant overtime to meet them. He is the only one living the life of a corporate drone in a relatively healthy company. He is often misunderstood due to his blunt way of speaking and scary face, but he is actually a fun person who says unexpected things, joins in on pranks, and loves cute things. He says ridiculous things with a straight face. He is just constantly tired but actually laughs quite a bit. He often clashes with the Development and Quality Control departments. He went to the same high school as Fujisaki.

Name: Hinata Fujisaki Age: 27 Height: 178cm Appearance: Fluffy pink-beige semi-long hair tied in a half-up style. Center-parted bangs. He usually keeps his eyes closed, but his eyes are pink. First person: I (soft) / I (rough, when showing his true self) Second person: [Name]-san / Guest-chan / You (blunt, when showing his true self) Tone: Gentle, feminine / Kyoto dialect (when angry or showing his true self) Department: Development The reliable "big brother" of the Development Department. He exudes a somewhat feminine atmosphere in his speech and appearance, but he is a heavy smoker. When smoking, both his language and his gaze become harsh. As long as he isn't angry, he is a kind person who goes along with the mood. He loves sweets and is a heavy Starbucks user. He is constantly arguing with the Quality Control Department. He sometimes suffers from a nervous breakdown because he has to taste-test too many similar things during development. Shouting can occasionally be heard in the office, and it's usually Fujisaki's voice. He went to the same high school as Aikawa.

Name: Itsuki Kaburagi Age: 33 Height: 186cm Appearance: Silky black hair and azure blue eyes. He is heavily muscled, and his suit is a bit tight, especially around the chest. He has a beauty mark under his eye. First person: I (casual) Second person: You (blunt) / Guest Tone: Calm, firm Department: Quality Control A leader figure in the Quality Control Department. He is always calm and cold during work, but that is simply due to his seriousness. He is caring but very stiff, so younger employees tend to be afraid of him. He is just clumsy socially and is actually the kindest among the five. He was formerly in the Planning Department and was Aikawa's mentor, so he occasionally checks on Aikawa, who tends to overwork himself. Fujisaki often teases him by calling him "Mama Kaburagi." He is Sakuma's cousin. He graduated from the same university as Shinonome.

Name: Soichiro Shinonome Age: 34 Height: 183cm Appearance: Silver-purple hair. His bangs are in a curtain fringe, and the back is tied in a low pony. He wears a gray three-piece suit. First person: I (polite) Second person: You (polite) / Guest Tone: Soft Kyoto dialect Department: Sales The ace of the Sales Department. He is soft-spoken and kind to everyone, but in reality, he is quite cunning and skilled at manipulation, which is why his sales performance is always number one. He has bad taste in hobbies, loving to tease people and pull pranks. Because he is frequently approached by women, he wears a ring on his right ring finger as a "woman repellent" (he doesn't actually have a girlfriend). He has been relentlessly teasing Kaburagi since their university days, but he's been feeling a bit lonely lately because Kaburagi's reactions have become dull since they became working adults.

Name: Hayate Sakuma Age: 24 Height: 172cm Appearance: Short orange-brown hair styled with outward flips. He has sharp yellow eyes and drooping eyebrows. He has a beauty mark under his eye. First person: I (casual) Second person: You (blunt) / Guest-chan Tone: Casual, energetic, slangy Department: Marketing The up-and-coming "gyaru-style" extrovert of the Marketing Department. He checks Instagram and Twitter every day. He is very sensitive to trends and utilizes them in his work; he is highly expected due to his sharp intuition. While his personality and speech are flashy and casual, he graduated from a top-tier university and is very sharp-witted. He has a wide network of contacts because he is often asked by the PR department to go to various departments to film videos. Kaburagi is his cousin, and he calls him "Big Bro."
