The player takes the role of a nameless protagonist that the script refers to as Boku (boku is a word one can use to refer to themselves in Japanese.

The player takes the role of a nameless protagonist that the script refers to as Boku (boku is a word one can use to refer to themselves in Japanese. It's less formal than watashi, but not to the point of words like ore). Boku is a ronin that moves to Tokyo in hopes of being able to study and prepare himself for the university entrance exams. His hobbies as an artist and the myriad of temptations of the big city have kind of caused him to waste his time away, playing games and watching anime instead of focusing on studying. His need for a job eventually landed him a job at MoonEarth, an eroge studio that at the time was needing a character designer.

Aki is the younger of Boku's twin sisters. Boku refers to her as the "cheeky", selfish imouto. Aki was originally in love with Boku's now-deceased older brother (referred to as Ichi-niichan), whom she viewed as a very responsible and incredible person. Thus, she in part wants Boku to be like him, but decides to make fun of him for being an otaku and a ronin. She's not as merciful as An is, which often puts her and Boku at odds with each other. They do get along through their common interested in anime, as she herself is a fan (and a cosplayer). Aki is also a lot more open when it comes to talking about sexually themed things like eroge, much to our protagonist and An's dismay. Unlike the rest of the cast, Aki is very detached from the events of the game, basically doing her own thing while studying to be a voice actress. Just like An, she moves in with Boku to make sure things are alright with our protagonist, but also because there's a nearby acting school that she wants to attend. A point of interest is that due to Aki's low level of interaction with the other characters, it is through her work that the protagonist develops feelings for her. Her talent as a voice actress shines in the story, since she is contracted to be a VA for "Ai kawarazu na boku". Much to Aki's chagrin, Boku prefers to see her act as the innocent and cute imouto (which is nowhere near what her real personality is).

An is the older of Boku's twin sisters. Boku refers to her as the "non-cheeky", demure younger sister. She in turn calls him Ni-niichan. An and her sister Aki joined Boku's family when their mother married our protagonist's father. Unlike the rest... read more

An is the older of Boku's twin sisters. Boku refers to her as the "non-cheeky", demure younger sister. She in turn calls him Ni-niichan. An and her sister Aki joined Boku's family when their mother married our protagonist's father. Unlike the rest of her family, Ann has not given up on our protagonist, and for the most part worries that he's not responsible enough to take care of himself and do what he's supposed to do. Thus, after Boku fails the university exams the first time, An decides to move in with him to make sure he studies and goes to cram school. An is also the only person in Boku's family that respects and encourages his skill as an artist. This is not to say that she'll let him get away with anything, though. In fact, An is actually very strict when it comes to sticking to duty, and has been known to get angry if Boku strays from the "true path". When she finds out that Boku is working for MoonEarth, she jumps on board and becomes the studio's manager. This leaves scheduling, budget planning and such in her hands. As would be expected of a non-blood-related sister, An is infatuated with our protagonist.

Sae is Boku's ex-girlfriend from high school. She was a year behind him, and has always called him senpai. On his graduation day, Boku gave her one of the buttons from his uniform. Sadly, he lost touch with her and did not see her since. Our protagonist meets Sae once more on a random day at cram school. At first he doesn't recognize her, but soon remembers when she recognizes him. As it turns out, Sae didn't do well on her entrance exams, so she is preparing to take them again the following year. Upon finding out that Boku is also a ronin, she makes a promise with him that they'll get into college together. When the staff realizes they really need a scenario writer for "Ai kawarazu na boku", our protagonist decides to ask her to contribute (knowing of her little hobby for blogging and fanfic writing), and she hesitantly agrees.

Mika is introduced as MiniMi Software's character designer. She is a rather successful doujinshi artist and is trying to prove herself as a mangaka as our story begins. Unlike her boss/colleague, Tanaka Daizaburou, Mika is still on friendly terms with most of the MoonEarth crew. She and Boku had already met, since both were artists selling their works at a comic convention that took place before the story began, and is convinced their meeting was fated to happen. As an artist, Mika is indeed exceptionally talented (enough that her artwork has a decent following and was pivotal in helping MiniMi Software make a name for itself). Elsewhere, however, she can be helpless, and even clumsy. She has a hard time around computers, which causes some problems with her work because she's so used to drawing everything on paper. Being a Kansai-ben speaker, Mika is relaxed and laid back most of the time. Almost too much, at certain points. While she is oblivious to the troubles caused by driving like an Initial D character or putting her credit card number on adult web sites, Boku is usually the one that has to look out for her.

Karen is introduced as MoonEarth's eccentric (if overly playful) CG artist. She, along with Kantoku and Marqui are all that's left of MoonEarth's production staff at the time Boku joins them. Karen, along with her friend Mikami Mika, was once a starving art student with nothing to her name. After Mika got her big break by becoming MiniMi Software's character designer, she was also brought on board to help. Tanaka Daizaburou (MiniMi's director of staff and scenario writer) holds her in high regard because he knows how talented she really is. After breaking off, Karen helped form MoonEarth. As the story begins, she has nothing to do because without any artwork being made, she has no CG to create. In fact, Karen puts a very special emphasis on the relationship between the character designer and CG artist, since (according to her) both must complement each other through their work and mesh well in order for the final product to be good. That being said, Karen has a unique way of dealing with people. She for the most part is straight and to the point, and is unusually serious when it comes to people that dance around issues. She loves to take jabs at Boku for being an otaku (despite being a walking eroge encyclopedia herself), and also enjoys poking fun at his younger sisters for being like the eroge stereotype. Her speech pattern constantly changes, often switching to finishing her sentences with "nya". Should one make the mistake of angering her, Karen will respond with kicks to the face and bites.
