Daisuke Namikawa

Miina Miyafuji

Utama

Miina tends to have a hyperactive personality and is generally outgoing. Eventually, she develops feelings for Maiku but is afraid to act on them since she might in fact be his sister. She outwardly expresses herself as happy-go-lucky, although she is actually hiding things about her past.

Mai Nakahara

Karen Onodera

Utama

She's a bit withdrawn, and has the same blue eyes that Maiku and Miina have. Having been brought through an all-girl's school, she hasn't had much contact with boys. She has a habit of fainting with a "Nyuuuuun" whenever she has a shock to the system. She's also living under Maiku's roof. Like Miina, she also develops feelings for Maiku, though she doesn't act on them for the same reasons as Miina.

Ai Shimizu

Mizuho Kazami

Pendukung

Female · Umur 23

Height: 170 cm Status: Galaxy Federation resident observer Mizuho is no ordinary high school teacher. She is actually a resident observer for the Galaxy Federation. Right after she lands on Earth, Kei sees her materialize. The next morning by the lake, he discovers that she is his homeroom teacher, and his neighbor. Mizuho has many different personalities. Though she is 23, and her father was human, she knows little to nothing about Earth except a love of the best candy in Japan. She has two living relatives, her mother and sister. Her sister, Maho, threatens Kei every time she sees him, and more than once tried to kill him.

Kikuko Inoue

Kei Kusanagi

Pendukung

Male · Umur 15 (physically), 18 (mentally)

Height: 155 cm Kei is living the life of a fifteen-year-old boy. He has a unique disease that causes his body to shut down into a death-like state whenever he becomes too stressed or depressed. He calls this a "standstill". The amount of time he remains in a standstill is random, usually lasting a few minutes to a few hours. However, one time, he went to a standstill and didn't come out for three years. So although everyone thinks he's 15, he is really 18. He discovers that his new teacher, Mizuho Kazami, is actually an alien whose mission is to observe Earth. Due to a big misunderstanding, Kei has to choose between letting her secret out or getting married to her.

Souichirou Hoshi

Ichigo Morino

Pendukung

Female · Umur 15 (physically), 21 (mentally)

A young woman who is seemingly wise beyond her apparent years, and who associates with very few friends. Her physical development was stunted due to her "standstills", in the same way that they affect Kei. Ichigo's loss of time and her sense of life cruelly having passed her by due to the illness tends to cause her to have a much more cynical and serious demeanor than is normal for someone of her seeming age. In order to prevent the triggering of "standstills", her emotional expression is very subdued.

Yukari Tamura

Kousei Shimazaki

Pendukung

One of Maiku's close friends, he often pretends to be gay (frequently hitting on Maiku, to the latter's disgust), but harbors deep feelings for Tsubaki Oribe.

Kenichi Suzumura

Tsubaki Oribe

Pendukung

She is the vice president of the student council and usually has a very serious personality. Intelligent and outgoing, gifted with a busty figure and possessing a more mature personality than the 'twin' girls, she is a source of concern for Karen and Miina as being an obvious rival for Maiku's affections. Her attempts to interest Maiku in a relationship, however, are met with Maiku's tacit plea for just friendship. It is not until she confers with Ichigo that she realizes that Maiku cannot engage in any casual romantic relationship due to both his obligations to his new-found 'family' and his own forcibly matured, responsible nature. This causes her to gain a higher degree of respect for Maiku, and to focus her attentions on the one person she once thought too forceful in expressing his affection for her, Kousei.

Michiko Neya

Koishi Herikawa

Pendukung

Female · Umur 16

Height: 154 cm Koishi is one of Kei's closest friends who also pursues a romantic relationship with him, but discovers her affection for one of her teachers, Yamada. This inappropriate relationship is only ever hinted at, but it's more than obvious that something is going on between them when Yamada is confronted by the principal about him seeing Yamada and a girl from their school walking together. Her parents own a grocery store and she often has to go to deliver food that people ordered. Koishi has a happy-disposition to her personality and is only ever seen crying when it comes to matters that involve Kei. One of the things Ichigo would get irritated at was that Koishi would never act on her urges and in effect, she waits too long, and by the time she does tell Kei her true feelings, he's already hopelessly in love with Mizuho.

Ayako Kawasumi

Kaede Misumi

Pendukung

Female

One of Kei's friends, Kaede tends to be a rather shy girl most of the time. Despite her shyness, during an accidental visit to her hotel room by a sleep-deprived Hyousuke, in which he mistakenly climbed into her bed, she awoke from a lightly inebriated slumber and claimed that he had appeared to her in a dream which now seems to have come true. She then sweetly confesses her love for him and proceeds to seduce him. The two become inseparable and are seen together throughout the series.

Sayaka Oohara

Matagu Shidou

Pendukung

Male

A rather serious student who is also into astronomy, Matagu seems to be the most hopeless of the cast, a classic "nerd". He is much less confident and self-assured than Hyousuke, or even Kei, leading one to conclude that he suffers from crippling shyness. His stated fondest dream is to meet with "an alien creature from outer space", totally unaware of the fact that his teacher certainly qualifies as such, and that he has had several conversations with his life's dream in a very normal setting. He even considered to confess his love to her, but his shyness put a halt to his plans.

Hiroaki Miura

Marie

Pendukung

A quasi-organic master control program for Mizuho's ship. Totally self-repairing and maintenance free. Hovers around in an innertube and on occasion plays a miniature guitar. Due to Kei fearfully striking 'him' during an initial escape attempt when Mizuho revealed her true identity, Marie's programming became scrambled, endangering both Kei and Mizuho. Communicating partly through indistinct sounds and through gestures, Marie is essentially a portable link to the ship's operating system.

Tomoko Kaneda

Haruko Shidou

Pendukung

Haruko is the little sister of Matagu Shidou, who is always watching her and doting on her. She is also the friend and classmate of Karen Onodera and Miina Miyafuji. She is a bit naive, and it always happy and energetic.

Ryouko Shintani

Yuuka Yashiro

Pendukung

Minna's friend from middle school.

Miyuki Sawashiro
