• Portal — yes Chocotto Sister is a Japanese manga series written by Gō Zappa and illustrated by Sakura Takeuchi. It was published in Hakusensha's seinen manga magazine Young Animal from 2003 to 2007, with its chapters collected in eight tankōbon volumes. The series has been adapted into a 24-episode anime television series by Nomad, airing in 2006 and released on eight DVDs.

The story centers around a Christmas wish made by a young Haruma Kawagoe, who was eagerly anticipating having a baby sister, after his mother suffered a miscarriage followed by a hysterectomy. Several years later, when Haruma is a college student, a woman on a flying motorbike claiming to be Santa Claus delivers his wish, a younger sister. When he remarks that he made his wish a long time ago, "Santa" replies that making a little sister takes a lot more time than just making an android, takes his signature for delivery, and departs. Haruma now has a little sister, who comes with her own instruction manual—a manual for how to be a little sister, that is. When she asks him to name her, he calls her Choko, which refers to 3=anchoko, the Japanese word for "cheat sheet" or "study guide".

• Choko • Momoko Saito • Choko is the titular heroine and the little sister that "Santa" delivers to Haruma. She is a sweet and innocent girl who seems to be about 10 years younger than Haruma. • Haruma Kawagoe • Daisuke Hirakawa • Haruma is the main protagonist and a young man in university. He has a crush on Ayano Sonozaki, the owner of the local flower shop, but is heartbroken after she decides to reunite with her ex-boyfriend. • Chitose Serikawa • Kaori Mizuhashi • Chitose is the granddaughter of the original landlady. She is a nice, yet somewhat shy and accident-prone young woman without a sense of direction. • Makoto Ashirai • Rika Morinaga • Makoto is young woman who lives in Tsubaki manor, the same building where Haruma, Choko and Yasuoka live. • Yasuoka • Kenichi Mochizuki • Haruma's neighbor in Tsubaki manor, Yasuoka is a middle-aged man whose existence Haruma had forgotten about until they meet at a local shrine on the New Year's Day after Choko's appearance. Yasuoka is unemployed and seems to be struggling to find a new job after having lost his wife and daughter about a year before the present. • Ayano Sonozaki • Sayaka Ohara • Ayano is a woman who runs Ciel blue de fleur, a flower shop near Tsubuki's manor. • Kakeru Ishida • Yumiko Kobayashi • Kakeru is a rather shy young boy around Choko's age. He saves Choko from a nasty fall and soon develops a strong crush on her. He works at his family's public bath and lives on the premises with three older sisters. • Yurika Hanayamada • Rie Kugimiya • Yurika is a young girl who seems to be around Choko's age or a little younger. She is from a rich family and lives alone in a big house with only a maid who tends to her since her father is often away on business. Yurika is forced to take on many activities typically associated with the upper classes including: ballet, violin lessons, home schooling with a tutor, and conversational English lessons, all of which she dislikes. Although Yurika initially hated Choko, she comes to care for her as they get to know each other better. • Tamami Marumo • Yuki Matsuoka • Tamami is a young woman who is Haruma's senpai both at school and in the club he belongs to. Tamami gives the impression of being quite free-spirited. She helps Haruma and other fellow students find part-time jobs, often on short notice, but Haruma is not fond of them as they tend to be "too busy" or not pay as much as he would like. • Kanrinin-san • The original manager of Tsubaki manor, where Haruma, Choko, Yasuoka, and Makoto all live. She has no other name and is a kind-faced widow who is getting on in years and seems quite easygoing. • Kazuya Sawamori • Ken Narita • Kazuya is the man who was previously engaged to Ayano and used to hold a position as illustrator with a magazine. • "Santa" • Rio Natsuki • Claiming to be Santa Claus, Santa is a rather tough-looking woman who rides a flying motorbike with reindeer antler-style handlebars and who does not have much time for chitchat or objections. • Midori • Yuka Koyama • Midori is a mature woman whom Choko first encountered in the public bath where Kakeru lives and works. She is a woman of firm convictions about the proper way to behave in a public bath.
