Multi’s “sister.� Serio is also a maid robot, designed at the same time as Multi, but by a different division of the company. She is an excellent maid. She’s very efficient, cooks well, and completes all her duties in a timely manner. However, Serio has a rather cold, unemotional, “matter-of-fact� personality. She is polite, but shows none of the heart that Multi does. (Source: RightStuf)

He is Nerine's father and the lord of the realm of the devils. Like the King of Gods, he too has a habit of embarrassing his daughter.
Tomoko is the class rep for Class 2-B, and she takes her duties very seriously. She’s always quiet and straight-laced; there seems to be a sort of tired determination about her. Many of the students make fun of her because of her position, but she simply ignores them and continues on her way. There is no pride in her actions. She is always fair, and will do what’s best, even if it isn’t her own idea. (Source: RightStuf)

Age: 17 Height: 170cm Weight: 55kg Rin Tsuchimi is a seventeen year-old high school student and the male protagonist in the series. In the game, Rin is the role that the player assumes. As noted by Kaede, Rin's main virtue is his kindness. This is both his greatest strength, as the girls love him because of this, and his greatest weakness, as shown later in the series by his indecisiveness and goal to make everyone happy, which usually ends up hurting them instead. Rin tends to show minimal initiative when dealing with the girls around him (mostly because of the abuse he receives by fellow male classmates over his perceived relationship with his childhood friend Kaede). However, he starts to spend more and more time with both Lisianthus (Sia) and Nerine after they arrive and starts to develop feelings for them. With regards to Kaede, he thinks of her as a childhood friend only. When people comment that he and Kaede would make a good couple, Rin either waves it off or says that it is strange to think of it that way. This distance kept between them is caused in part by Kaede and Rin's dark past. (Source: Wikipedia)
