CHARACTERS

Yamada Family

Yamada (山田 Yamada?)
Voiced by: Yukari Tamura[4]
Yamada is a 15 year old high school girl who is best described as oversexed, flirtatious and lustful. She is particularly vain and is unabashed in flaunting her looks in public. Upon entering high school, her goal was to have intimate relations with 100 different men; however, her insecurities as a virgin caused her to turn down any advances. Yamada believes the first step towards realizing her dreams is to lose her virginity to an inexperienced boy. This leads her to pursue Takashi Kosuda. While initially seeing him as a tool for her lust, over time she starts to develop genuine feelings for him which includes jealousy when she finds him in the presence of another female companion. Despite living at home with her younger sister, Yamada is unashamed in her licentious habits, which involve highlighting sexual terms in the dictionary, collecting erotic magazines which she keeps in her room, even taking pictures of animals having sex or downloading hundreds of uncensored penises.
Aiding her towards her goals is a personal deity who takes on the appearance of a super deformed version of Yamada, save the mustache, and floats around on a pink cloud. This character also acts as a narrator at times, calling herself the sage of lust Ero-God, recapping past events as well as occasionally breaking the fourth wall to address the audience.
Chika Yamada (山田 チカ Yamada Chika?)
Voiced by: Asami Shimoda
Yamada's little sister, who because of all her sister's perverted interests, is completely unaffected to such nature. She is very popular, often using her cuteness to get boys to give her whatever she wants, a trait she inherited from her mother. This experience however allows her to clearly see what is going on in Yamada's love life. In the manga it is said that although she already has many boyfriends, she is still a virgin so far.
She too has a Lust God, but it takes the form of an exact copy of her and overlaps with her real self, making her and her Lust God completely synchronised.

Kosuda Family

Takashi Kosuda (小須田 崇 Kosuda Takashi?)
Voiced by: Atsushi Abe[4]
Takashi Kosuda is one of Yamada's classmates, and is the main subject of her lust throughout the series. Characterized as inept, sheepish and indecisive, he is also kind-hearted and often tries to look out for Yamada when he can. Takashi is initially taken by her advances, but that later turns into confusion and anxiety, due to the mixed signals between them, as well as his insecurities as a virgin. He lives at home with his older sister, who is a college student. One of his hobbies is photography. He is afraid of heights. Takashi has had feeling for Yamada for most of the beginning, to the end.
His Ero God appears to look just like him, except with a more lazy attitude and always seen in a bathrobe.
Kazuki Kosuda (小須田 香月 Kosuda Kazuki?)
Voiced by: Mamiko Noto[4]
Kazuki Kosuda is the older sister of Takashi, who is a college student living at home. Though often teasing her brother, she deeply cares for him. She is also not shy, and often walks around the house naked or barely dressed despite her brother being there, much to his objection.

Others

Miharu Takeshita (竹下 美春 Takeshita Miharu?)
Voiced by: Yui Horie[4]
Miharu Takeshita is the best friend and classmate of Yamada. Despite her friend's prurient interests, Miharu tries her best to be of help, even going so far as to invite Takashi on a double date at the water park. At times, she is the subject of Yamada's envy due to her bustiness of which earned her the moniker "F-shita" as a reference to her cup size. She also has a boyfriend whom she rarely talks about because of Yamada and her lewd prying. In manga, she is the only character so far to be not a virgin. It is hinted that she lost virgin to her boyfriend right after her junior high school gratuation. She later becomes friends with Mayu, often helping her cook, where she truly believes that Mayu should end up with Takashi due to her pure innocent love for him rather than her friend Yamada who is only after him to lose her virginity.
Unlike the other characters she actually has two Lust Gods, one of her in a sexy dress, and the other dressed in a business attire. She believes the sexy dress side is because of spending time with Yamada.
Mayu Miyano (宮野 まゆ Miyano Mayu?)
Voiced by: Kana Hanazawa[4]
Mayu Miyano is the childhood friend of Takashi who lives directly across the street from their house. She is depicted as a busty meganekko who is ditsy and has a timid personality. Mayu secretly has feelings for Takashi but doesn't have the courage to confess to him. Because of this and her close history with Takashi, she is perceived by Yamada as a rival for his virginity. One of her favorite hobbies is cooking. Her first love was actually Takashi's sister Kazuki, who she thought was a boy. It might be because of this why Takashi is completely oblivious to her feelings, as when they were children she stated she already liked somebody, where he still believes she is in love with a boy with the same name as his sister. She also has a habit of blurting out odd intentions, like when she was trying to get up the courage to enter his house to give him food, she spots him returning home and states, "I made you lunch, I wasn't spying!"
She too has a Lust God, but she is in the form of a cute small fairy that is as innocent as she is. For example, suggesting she to kiss the cookies she was going to give to Takashi for an indirect kiss.

Kanejō Family

Kyōka Kanejō (金城 京香 Kanejō Kyōka?)

She has an excessive brother complex to where she has a secret room filled with nothing but his image, to a point where she wants her own brother, Keiichi Kanejō, to take her virginity away from her. She will do absolutely anything at all costs to win his affection but unfortunately for her, he is currently studying in Harvard where she can not follow.
She too has a Lust God who resembles her but wears a noblewoman's attire, complete with fan. Since they both share the same combative personality with a superiority complex, they often don't get along very well.
Keiichi Kanejō (金城 圭一 Kanejō Keiichi?)
Kanejō's brother, who came from America (probably Harvard University). He is the object of every woman's infatuation, even a princess from a foreign country could not withstand his "charm". He later returns, but has seemingly gained an interest in Yamada, much to Kyoka's chagrin, this most likely because she is so far the only woman that has not instantly fawned over him. He reveals he is a virgin, though unaware of the fact his sister uses her power to do so. At the end of the anime, he wished to lose his virginity to Yamada.
