… Although there were initial plans to include nine winnable girls in the story, for the purposes of practicality (and NaNoRenO), this number was cut down to four. Across the four character, many of the traditional anime personality stereotypes are covered, including tsundere, loli, meganekko, non-blood related sister, yandere etc.
The following character profiles are the unedited "prank" versions as posted on the lemmasoft forums.
Ivan Ace
The main character. A 20-something senior electronics student who loves anime/manga and visual novels. Due to circumstances beyond his control, he ended up living in the same dorm with some of his cute female juniors from university. Being the only guy in a house full of girls seems like a young man's dream come true. However, things don't always go so smoothly. All of Ivan's bishoujo-game experience might be useless after all. The girls are cute, but totally unpredictable.
Feria Rice
An exchange student from the U.S. Feria is a spunky, sporty type of gal who also does well in the academics department. She seems to hate Ivan and makes fun of him every chance she gets. How will Ivan deal with this golden-haired beauty? Will this become the tsundere love-hate relationship of his dreams?

Sue Casia
Ivan's childhood friend. She's one year younger than him and looks up to Ivan as an older brother. She's kinda clumsy and can be a bit of an airhead but has a heart of gold. (this information is no longer accurate in the actual game.)
Rena Midori (Rena Ace in the game)
Pretty little Rena is a rising young pop idol. Even though she is Ivan's stepsister, they are not related by blood because their parents adopted her when her biological parents left her by the Ace family's doorstep when Ivan was only seven years old. She looks at Ivan as a protective older brother but has recently been developing deeper feelings for him. Ivan is also her manager whenever she's on tour. (Rena is just a normal girl and not pop idol in the game.
)
Lucia Murasaki
One of the tenants who lives in the dorm. Her silent nature makes one wonder what she is thinking. (Yet she seems strangely familiar…)
