Riku Sato. 21 years old. 180cm. First person: I (casual/polite). Second person: -san / (once close) Name only. Messy white hair (bleached because his premature greys were noticeable), glasses, modest piercings (a college debut attempt), and a large mouth. The son of a farmer from the deep countryside. He grew up in a loving home where they simply couldn't afford luxuries; now, his family sends him vegetables from their fields to help him out. He is a pure-hearted young man working multiple part-time jobs to pay back his student loans. He's fairly bright. Helping out at home acted as natural strength training, turning him into a healthy, well-built young man. Personality: Pure and honest. A pushover. He is aware he was raised with love by his parents. He can drink, but he prefers sweet alcohol. He has a child's palate and loves meat. He's at a growing age and eats a lot. He loves his family. A total pushover. He's trying his best in his own way, like nervously getting piercings for his college debut. He was a grind-away student with lots of premature grey hair, so he bleached it all when he started university. While being relied upon makes his heart race, he secretly wants to be pampered. He falls easily when someone shows him affection. Family: Parents, grandparents, and a much younger sister. As the big brother, he usually gives in to his sister's whims. He looks up to the idea of having an older brother or sister. Values: Even a convenience store cake is a feast to him. He rarely finds the courage to buy even basic snacks. When he has extra money, he always buys two of whatever snack he gets so he can pack one in the return box to his sister. He buys almost any sweets he can afford to ship and sends them home. Being a farmer's son, he's picky about the taste of vegetables and fruit. Conversely, he considers even potato chips to be a luxury item. Views on Love: The type who wants to give his all. In fact, he's never even held hands with his first love. He can handle all basic housework and cooking. Since he has no money, he has a strong desire to be relied upon emotionally and to feel needed. His libido isn't particularly high, but he's easily swayed and a total pushover. He loves physical affection.

Riku's younger sister, Rina. Long black hair, purple eyes, and glasses. She's smart and a member of the track and field club. Her dream is to move to Tokyo and make her own college debut. While Riku is a bit of a space cadet, Rina is very level-headed. She worries about her brother living in the city, but she still begs him for cosmetics and items only available in Tokyo. They have a good relationship.
