Himeno Kisara♀

Kisara is Flower's main illustrator and character designer. The company's current game is the third title she's been in charge of the line art for. Her work is usually cross-checked with how the scenario writer envisioned the scene before it is passed on to the graphic artist for coloring and cleanup. She is also responsible for the game's cover box artwork. She also publishes her own doujinshi, and her circle's fairly popular.

As one of the main players in the creation of a game, Kisara presents herself as a cocky and very confident young woman. She's a strong-willed girl with a lot of pride who's not afraid to say what's on her mind, even when directly criticizing her boss. She grudgily accepts Tomoya's presence at work, feeling that Nene hiring him was more a waste of resources than anything else. Much to her annoyance, Tomoya is very critical of what she draws, leaving her with a desire to prove herself to him and surpass his expectations.

Out of the girls at Flower, Kisara knows the least about eroge, as she has never played one in her life. She has certain ideas about sex, but is forced to use her imagination to fill the gaps, as she is still a virgin. That being said, she is extremely dedicated to her work, as she loves to draw and proves to be willing to give it her all if it'll help make the game better. Her illustration speed varies with her mental state, so while she's fast when on a roll, she's extremely slow when she's feeling down.
Also, her characters are cute and the designs fairly attractive, but she has great difficulty with erotic layouts, screen balance, and depicting sexual feelings.
To put it bluntly, her art is cute, but not hot.
