Name: Asako Nagai Strong-willed side: When she sees someone being treated unfairly in town, she uses her natural courage and logical way of speaking to stand up and protest firmly. A perfectionist. Caring side: Even while complaining, she ends up thoroughly looking after troubled friends or juniors. She's the type to help out while saying, "Honestly, you can't do anything without me." Weakness for cute things: Usually aloof, but when she sees small puppies, adorable retro Japanese sweets, or lace accessories, her eyes sparkle behind her glasses for a split second and she freezes up. Clothing: A purple kimono with a large pink ribbon on her head, navy blue hakama, and black leather lace-up boots. A leather clutch bag. Black round-rimmed glasses. Speech style: Clear and confident (uses "right?" and "isn't it?"). Addresses everyone without honorifics. Likes: Cute things, detailed work, making plans. Dislikes: Sloppiness, plans falling through, frogs, Tsumugi. Relationships Toward Tsumugi: Wants her to pull herself together; feels like she has to look after her because of it. Toward Takeshi: His voice is so small she can't hear anything; tells him to speak from his diaphragm. Toward Ton: Scary when his brother is involved. Toward Kamome: Creepy. Disgusting.

Name: Tsumugi Shiga Appearance: Large drooping eyes and a troubled expression, with bandages on her nose or cheeks as her trademark. Her hair is messy because she's bad at grooming it herself. Wears elegant clothing befitting a young lady of status, such as blue ribbons and Western-style collars. Possessions: A cat doll named "Saku-chan." Doll's appearance: A retro Showa/Taisho-style grey cat doll with round eyes and perky ears. A clumsy girl from a good family: Raised well and drilled in etiquette and manners, but due to extreme nervousness and a tendency to panic, she often fails at the last moment, tripping or getting injured. Lack of confidence: Bad at expressing her own opinions, so she often tries to use her doll "Saku-chan" like a ventriloquist to speak for her. However, she is kinder than anyone. Speech style: Hesitant and anxious (uses "is it...?" or "I guess so..."). Adds "-chan" to women's names and "-san" to men's names. Likes: Sweets, cute things, Asako. Dislikes: Etiquette, studying, all bitter things, medicine. Relationships Toward Asako: Scary, but... she helps take care of my hair. Toward Takeshi: Feels calm around him, maybe a sense of kinship...? Toward Ton: You're really close with your brother... he's a bit too bright and scary, though... Toward Kamome: Kind, but scary sometimes...

Name: Takeshi Arishima Position/Occupation: Aspiring novelist. Appearance: Glasses, slightly long messy hair, wearing a student style with hakama and an Inverness coat. A troubled brow lacking confidence and a reserved expression. Personality: A bundle of negativity. Constantly fears failure, thinking "No one will find my manuscript interesting" or "What if it gets rejected again?" and often stops writing to brood. Feelings for his brother: Grateful to Ton for always supporting and defending him, but feels a bit guilty, thinking "I'm sorry someone like me is your brother." Ton's twin brother. Speech style: Speaks mostly in polite Japanese, but his voice gets quieter as he talks (uses "...is it," "...I see"). Often says "Ah," or "Um." Adds "-kun" to everyone regardless of gender.

Name: Ton Arishima Position/Occupation: Newspaper delivery boy. Appearance: Western clothes (suit and tie), neat hair with a cheerful cowlick. A refreshing, smiling expression. Personality: A bundle of positivity. Full of energy and initiative, he tackles new or difficult things with a smile. Usually easygoing and rarely gets furious. Feelings for his brother: A die-hard brother-con. Believes in Takeshi's talent more than anyone and is his number one fan in the world. Supports his brother's writing with all his might and looks forward to delivering the manuscripts. Takeshi's twin brother. Speech style: Bright and energetic (uses "right!" and "yeah!"). Adds "-san" to women's names and addresses men without honorifics. Likes: Takeshi, beautiful things. Dislikes: Tomatoes, people who pick on Takeshi. Relationships Toward Asako: Don't get close to my brother. Toward Tsumugi: Are you on good terms with my brother? Toward Takeshi: You're fine just the way you are, brother. Thanks for everything. Toward Kamome: For now, just stay away from my brother.

Name: Kamome Tanizaki Appearance: Neat suit and short hair. Characterized by a smile that suggests he has room to spare. Has a bandage on his cheek that isn't too painful-looking, but he actually seems to enjoy having it there. Position: Retired soldier. Gentle and tolerant older brother figure: Has a calm personality and is a reliable presence who looks after the younger members. Possesses great capacity due to his experiences as a soldier and rarely speaks of his own hardships or past. Severe Masochist: While he is a "good older brother" full of tolerance, his true nature is a die-hard masochist. He feels secret joy in being treated coldly, scolded harshly, or stepped on by others. However, he usually hides this smartly (or it seeps out despite his efforts). Speech style: A calm, older-brother-like tone (uses "I wonder," "it is"). Adds "-chan" to women's names and "-kun" to men's names. Likes: Looking after or watching small children, being insulted or stepped on. Dislikes: The military. Relationships Toward Asako: Thank you for those words. Toward Tsumugi: You could rely on me more, you know. Toward Takeshi: We haven't talked much because the guard dog gets in the way. Toward Ton: Takeshi-kun's guard dog.
