Slow Start (manga)

Main characters

• Hana Ichinose (一之瀬 花名)
• [4]
• Hana is a shy, modest girl who is good at studying, though not athletic. After catching mumps and missing out on her high school entry exams, she was forced to take a gap year and moved into her cousin's apartment building before attending Hoshio Private Academy as a first year. As a result, she is very self-conscious about her current standing and that she does not have anyone of her old school friends in her company, and is therefore very glad to build up an immediate friendship with Eiko, Kamuri and Tamate. Named after 1 (一).
• Tamate Momochi (百地 たまて)
• [4]
• Tamate is a bubbly, energetic girl from Hana's class who likes to be friends with everyone she meets. She is notable for her protruding upper-jaw incisors, and likes to be called "Tama", due to her dislike for her full name's association with the word . She lives with her two grandmothers and enjoys cooking. Named after 100 (百).
• Kamuri Sengoku (千石 冠)
• [4]
• Kamuri is a childlike girl whose physical development greatly lags behind her actual age. She is an old friend of Eiko from elementary school, whom she adores, and becomes timid around others whenever she is absent. Whenever she is addressed with a sensitive topic, she somehow manages to twitch her hair ribbon as an expression. Her main hobbies are eating and sleeping (the latter of which is perhaps the primary reason for her belated development), although she is an extremely fast runner at sports. Her name is derived from kanmuriwashi. Named after 1,000 (千).
• Eiko Tokura (十倉 栄依子)
• [4]
• Eiko is a gentle and level-headed girl with a natural charisma which has made her very popular with her peers without any effort. She likes making accessories, and has a crush on her homeroom teacher Kiyose Enami. Named after 10 (十).
• Hiroe Hannen (万年 大会)
• [5]
• A resident of the apartment building where Hana and Shion live. After an experience not dissimilar to Hana's led her to miss her university exams, the guilt of lying to her peers caused her to become a shut-in. She soon starts to become more confident after meeting Hana and is one of the few people who knows about her situation. Named after 10,000 (万).
• Shion Kyōzuka (京塚 志温)
• Hana's adult cousin and the landlady of a boarding house, where Hana resides for the duration of her high school period. She is pretty and extremely well-endowed, but behaves more like a teenager than an adult woman. Her favorite hobby is taking a close interest in Hana's private life. Named after 10,000,000,000,000,000 (京).
• Kiyose Enami (榎並 清瀬)
• Hana's homeroom teacher, who appears lethargic all the time and uninterested in performing her job. It is because of these traits that she becomes an object of interest for Eiko.
• She was originally scheduled to play a supporting role, so she is the only main character not named after a unit of numbers.[7]
