Makoto Niwa (丹羽 真 Niwa Makoto?)
Voiced by: Miyu Irino
Makoto is a second-year high school student and the protagonist of the story, who transfers into the city after his parents go overseas. He constantly tries to monitor his 'adolescence points', which rise and fall based on his encounters with other girls. He strongly disbelieves in the supernatural, like aliens, espers, etc.
Erio Tōwa (藤和 エリオ Tōwa Erio?)
Voiced by: Asuka Ōgame
Erio is Makoto's first cousin with blue hair growing down to her ankles and is almost always barefoot even when outside. She disappeared the previous June while she was a first-year in high school and went missing for six months. When she reappeared that November, she had no memory of what happened during that time. She also became extremely fascinated with aliens, believing herself to be an alien investigator monitoring humanity. Following an incident where she broke her leg while trying to fly on her bike, she started wrapping herself in a futon. Initially she is soft spoken and unsociable but eventually opens up due to Makoto's influence, which also included disproving her delusion of being an alien herself. She is reluctant to return to school (due to her shady reputation) so she gets a part time job at her great-grandmother's convenience store and even joins a pick-up baseball team to spend time with her cousin. Her birthday has apparently been forgotten, but her family decides to celebrate it on June 7, the day after her mother's birthday.
Meme Tōwa (藤和 女々 Tōwa Meme?)
Voiced by: Ai Nonaka
Meme is Makoto's aunt and Erio's mother. She also goes under the name Jojo and is an owner of a store that sells sweets. She is cheerful and often teases Makoto by attempting to seduce him. She has no plans to marry and is happy with her life with her daughter Erio and her nephew Makoto. She allows Erio to stay home from school and do as she pleases. She explains to Makoto that it is the only effective way to deal with her daughter's eccentricities. Ironically, her actions do not make her look any less eccentric than her daughter, but it is shown that she is actually wiser than she usually acts. Meme's birthday is June 6.
Ryūko Mifune (御船 流子 Mifune Ryūko?)
Voiced by: Emiri Katō
Mifune is Makoto's classmate who has a crush on him. Due to the kanji in her name, she is often nicknamed Ryūshi, which she does not particularly like. Correcting others when they address her as Ryūshi happens so often that it has almost become her catchphrase. She is vegetarian, referring to herself as a "fruitist" (fruitarian). She plays on the school's basketball team and has an energetic personality.
Maekawa (前川?)
Voiced by: Mai Fuchigami
Maekawa is another of Makoto's classmates who is very tall for a girl (she claims to be 179.9 cm tall) and always refers to Makoto as 'transfer student' as she can never get his name right. She is very calm and sometimes expressionless perhaps due to having a weak body and sometimes amuses herself by teasing Ryūko. She gets dizzy if she raises her arms over her head for more than ten seconds, and often wears various costumes. Her parents own a bar in the shopping district and she has several part-time jobs. She insists on wearing cosplay to work even when her supervisor insists she does not.
Yashiro Hoshimiya (星宮 社 Hoshimiya Yashiro?)
Voiced by: Yuka Iguchi

Ashiro (安代?)
Voiced by: Yasunori Matsumoto
