Main characters

Hyouga Akihito氷河 彰人
HairBrown, Curtained, Parted to Side, Short
EyesAmber, Hosome
ClothesBelt, Dress Shoes, Necktie, Shirt, Suit


The leader of the project you've been assigned to, and also the head of the development department. Harsh on others, and it's hard to tell what he's thinking. Doesn't say a single word more than needs to be said. Although he's arrogant and likes making people sweat with his sharp words, he has a tendency to surround himself only with people he deems are his type.

Kaidou Ryou海藤 遼
HairBlue, Short
ClothesGlasses, Necktie, Shirt, Suit


A hotshot from the PR department. He's serious about his work, and leaves a good first impression on people; seemingly a good guy all around. But as you get to know him, you find that he can be strikingly blunt in his criticism, and likes watching people squirm. Although he seems easy to get along with at first, that's just a façade. A master at changing personalities in the blink of an eye.

Kunizu Mahiro国津 真尋
HairOrange, Parted to Side, Short
ClothesNecklace, T-shirt


A designer who joined the company at the same time as you. On the surface, he's a cheerful guy who's easy to get along with and doesn't hide his feelings. But it turns out that when it comes to love, he takes the offensive -- and his target is you.

Ootori Haruyuki鳳 春幸
HairBrown, Curtained, Short
ClothesNecktie, Shirt, Suit
Engages inTeasing


Despite his young age, managed to become the CEO of a large corporation. Considerably famous for his business prowess and youth, his name often makes it in headlines. He leaves a lasting impression on people due to his charming smile and handsome looks. Has a tendency to ask unreasonable things of his employees all while wearing a smile. He was the one who ordered Hyoga Akihito to create a new team to develop a new product in time for Christmas.

Saijou Sadayoshi西城 貞義
HairGrey, V Bangs


Your former boss, and the leader of the sales department. Has a calm disposition, but is good at his job and is able to approach a situation from the other person's point of view. But beneath that calm surface lies a jealous and possessive heart; get too close, and before you know it you'll be trapped in his cage. Capable of manipulating people to get what he wants without batting an eye.
