■Story In the year 20XX in Japan―― A law known as "Love Communication Studies Act," which mandates the establishment of a subject called "Love Communication Studies" (commonly referred to as "Love Comyu Studies") as a required course in all schools, has been enacted. At this time, the protagonist, Hiroya Funaki, who has spent a long time abroad, returns to his hometown in Japan after a long absence. He will be living in Japan with the family of his childhood friends, the older sisters he played with when he was young. They have grown into beautiful women, now serving as teachers and senior students at the academy. Hiroya has spent his life at a cutting-edge scientific research facility in Silicon Valley, America. There, he has dealt with highly confidential matters and high-tech devices that have not yet been released to the public, leading him to become a socially awkward, digital boy who struggles with interpersonal relationships. As a result, despite being at an age where boys typically show interest in girls, he has no interest in the opposite sex at all. The older sisters are worried. "If this continues, Hiroya will spend his life surrounded by machines and die alone...! To prevent that, we have to teach him the right way to love!" Thus begins the daily "Sister Lessons" led by the older sisters. --- Characters **The family's pillar. A cool older sister with love hidden in her sternness.** ● Rinka Nonomiya (CV: Nene Tsukimori) The eldest daughter of the Nonomiya family and a school nurse at the academy Hiroya attends. She also teaches the gender-related aspects of "Love Communication Studies." Her cool appearance and straightforward way of speaking make her popular among students, often approached by girls during lunch for advice. She reprimands wrongdoings firmly. Although she intends to be quite strict with Hiroya, she also has a sweet side, such as buying him the latest smartphone. Despite not being blood-related, she maintains a "sister and brother" relationship with Hiroya and disciplines herself to never cross that line. "It's my responsibility as his sister to guide him. What he does is my duty." --- **A free-spirited and family-oriented sexy older sister.** ● Sora Nonomiya (CV: Toa Yukimura) The second daughter of the Nonomiya family and the vice president of the academy Hiroya attends, currently acting as president due to the absence of the actual president. She also teaches math, specifically for Hiroya's class. Known for her carefree demeanor and flashy appearance, she is rumored to have manipulated many boys. In reality, she has been popular since her student days, receiving confessions almost daily. Even now, she is popular not just with male students but also with male teachers and vendors (however, she has no actual experience in dating). She has a strained relationship with her father, who is the president, but she is deeply family-oriented and will do anything to help her family in times of trouble. "I'll make sure Hiro enjoys his school life until graduation." --- **A muscle-headed older sister who can energize you just by being together.** ● Himari Nonomiya (CV: Ichika Kano) The third daughter of the Nonomiya family and a teacher at the academy Hiroya attends, specializing in health and physical education. A typical sports enthusiast, she excels at most sports. It seems she was expected to have a bright future in volleyball during her student days. To train Hiroya, who has little physical strength and hasn't exercised much, she decides to work out with him every day. However, she has a masochistic streak, sometimes shocking her sisters by deriving pleasure from getting hit by balls or enjoying muscle pain. She feels insecure about her height. "Hehe, leave it to me. Let's enjoy the ultimate pleasure of muscle pain." --- **An overly caring older sister who spoils her younger brother.** ● Ayaka Nonomiya (CV: Kinako Yatsuhashi) The fourth daughter of the Nonomiya family and a new teacher of "Love Communication Studies" at the academy Hiroya attends. She is overprotective and worry-prone. She spoils Hiroya thoroughly but seems unaware of it. Concerned that he might end up alone surrounded by machines without ever getting married, she is determined to teach him "Love Communication Studies" step by step. She has always loved romance novels, which influenced her interest in "Love Communication Studies." She adores stories about forbidden love between siblings but believes it's impossible to realize such a thing. "You can't do that! If it continues like this, Hiro-chan will end up dying alone surrounded by machines!" --- **A nurturing older sister with a motherly aura.** ● Minori Nonomiya (CV: Koko Umemiya) The fifth daughter of the Nonomiya family and a third-year student at the academy Hiroya attends. She is laid-back and rarely gets flustered. She excels in household chores like cooking and cleaning, taking on a motherly role despite being the youngest. Her sisters often rely on her. While the other sisters try to engage with Hiroya, Minori tends to give him space. Yet, things often seem to go her way without her even trying. Surprisingly, she is incredibly bad with technology, and the Nonomiya family's appliances are all outdated to accommodate her. "Hiroya-kun, it's breakfast time, but I wonder if you can wake up~?" --- **An indispensable small animal-like partner.** ● Momoko (CV: Misuzu Kazefuri) A care-animal android developed by Hanabishi Meditech, incorporating a foundational algorithm discovered by Hiroya. This is also the reason Hiroya had to return to Japan. She speaks in a cute, ninja-like tone, loves baths despite being a robot, and is surprisingly emotional, which Hiroya cannot quite grasp. After coming to the Nonomiya family, she bonds with Ayaka, often sleeping and bathing together. "Hiroya-dono has such wonderful older sisters, doesn't he?" --- **A good understanding friend. A childhood friend with a chuunibyou syndrome.** ● Kenji Ono A childhood friend of Hiroya from preschool, he was completely forgotten until they reunited after a long time. He is an otaku who loves anime and games and suffers from severe chuunibyou syndrome. Due to his overly distinctive way of speaking, he lived a solitary life until Hiroya transferred to the academy. Nevertheless, he becomes a friend with whom Hiroya can be himself. "My partner who has survived countless life-and-death situations! I'll come to help you right away, so please stay safe!" --- **Terribly bad at socializing! A reclusive boy who avoids relationships.** ● Hiroya Funaki The protagonist of this story. He spent his early years in Japan but moved to Silicon Valley, America, due to his parents' jobs. In Silicon Valley, he was called a genius for his AI programming skills, spending time in a specialized research facility instead of attending school. Having interacted mostly with computers and machines, he struggles immensely with socializing. He has grown up to be somewhat cynical and logical, rarely expressing emotions. Due to certain reasons, he returns to Japan after a long time, living with the Nonomiya sisters. Despite being a boy at an age where romance and sexual interest typically arise, he is an aloof boy with no interest in the opposite sex, but he finds himself responding when the sisters push him. "There’s no one I feel romantic feelings for, and I don’t need it."
