Name: Rinu Nickname: Rinu-kun Line: "What should we have for dinner tonight? Fried rice? Fried rice? Or maybe a Bow-wow Omelet Rice-y? ♡" The protagonist of the series, a dog boy. His image color is red. The energetic mood maker of the family. He's a cute, high-spirited jokester. However, he has a bright, kind, and loyal personality, and his words often move the hearts of others. Birthday: May 24th.

Name: Riken Nickname: Riken-kun Line: "Surround me, pay tribute to me, praise me." The other protagonist, a dog boy. His image color is light blue. He is Rinu's younger brother, partner, and rival. In contrast to his cute appearance, he is a sharp-tongued, black-hearted little devil. While he speaks harshly to Rinu, he actually cares for him deeply, even buying his albums—he just has a hard time being honest about his feelings. Birthday: April 1st.

Name: Rineko Nickname: Rineko-kun Line: "What should we have for dinner tonight? Fried rice? Fried rice? Or maybe a Meow-meow Omelet Rice-y?" The only sensible intellectual in the Rinu Family, a beautiful black cat boy. His image color is black. He is Rinu's best friend and the straight man to his antics. He's a bit of a tragic figure who suffers through being forgotten on his birthday, being forced into ridiculous situations, or being treated like a background character. Though he usually acts cool, he is actually kind and loyal, showing a tsundere side when he gets embarrassed by Rinu's open displays of friendship. Birthday: February 22nd.

Name: Riiko Nickname: Riiko-chan Line: "Great face! Great personality! Great proportions! All stats are 10 billion points! It's Riiko! ♡" The idol of the Rinu Family. A beautiful dog girl and the family's madonna with a perfect face, personality, and proportions. Her image color is pink. She was the sole female character until Riris arrived. She has a natural idol aura that even catches the attention of the Tiger brothers, but she can be quite sharp-tongued and has a bit of a tsundere side.

Name: Ritora Nickname: Ritora-kun Line: "Chorissu! First is hitting on girls, second is hitting on girls, third and fourth is hitting on girls, and fifth is hitting on girls! I love girls and hate handsome guys! I'm Ritora! Nice to meet ya from today! ☆" A flashy playboy tiger boy. His image color is yellow. He's cheerful and high-spirited, and while he loves girls, he isn't very popular with them. He is friendly and social with everyone. He hates handsome guys and is often jealous of his popular, handsome older brother Rion, yet he has a spoiled side where he calls him "Big Brother." He ends his sentences with "-ssu." Although he usually fails at flirting, he recently fell in love with Riris thanks to his bright and friendly nature.

Name: Riusa Nickname: Riusa-kun Line: "Sorry for being naturally cute!" A rabbit boy with a "menhera" and sickly-cute aesthetic. His image color is green. He generally speaks politely, but often ends up provoking others unintentionally. He is Riken's rival. Originally he was supposed to have asymmetrical hair, but it was changed to braids because it overlapped with Rineko. He hates matching with others and once tried to cut off his own braids when he saw Rinu imitating them. He and Rikuma are fellow lovers of cute things; they encourage each other when they feel their own appearances don't suit the things they find cute.

Name: Riris Nickname: Riris-chan Line: "I'll have you know, I have a damn short fuse!" A super-rich squirrel socialite. Her image color is orange. She is Riiko's rival. She speaks with a stereotypical high-class lady dialect, ending sentences with "-desu wa" (a style Rinu once used in an old broadcast). She has a lot of pride and seems strong-willed, but she is surprisingly delicate. When she was feeling down after overhearing other girls gossiping about her, Ritora spoke to her. Finding they had much in common and being called "cute" by the bright, friendly boy, she developed a crush. She is basically a tsundere but honest about her feelings.

Name: Rikuma Nickname: Rikuma-chan Line: "Isn't it fine to like the things you like?" A new member of the Rinu Family, a beautiful bear transfer student. Her image color is white. Despite being a girl, she is a prince-like handsome girl with a neutral appearance, very popular with the ladies. It wouldn't be an exaggeration to call her a beautiful woman in male clothing. (Ritora, who loves girls but hates handsome guys, has complicated feelings about her.) She is surprisingly a bit airheaded. She once wanted to buy a cute ribbon but was bullied for it being "too girly"; she encouraged Riusa when he was about to give up on his own ribbons. This led Riusa to admire her. She and Riusa are fellow lovers of cute things who support each other through their insecurities.

Name: Inuhachi Nickname: Inuhachi-sensei Line: "Alright, let's start today's class." The teacher of Rinu and his classmates. His image color is purple. He is the most easygoing, free-spirited person in the group. While he looks almost identical to Rinu, he is the most pitiable character—unlike Rinu, he is not popular at all and is frequently disliked.
