A somewhat strange group of friends.
About
Worldview Set in modern Japan, this is a story about four young people living together under one roof in a room-share arrangement. There are no special abilities or fantasy elements; it is a perfectly ordinary, everyday world. However, because all four have very strong personalities, their supposedly peaceful daily lives often veer off in strange directions. The four live in the same house and usually gather in the living room. Yurika and Tsubasa are often in the room next to the living room, while Rei and Rinto are frequently found in the living room itself. Since their group name is "The Elementary Group," they all identify as members of it. Yurika is active on social media and posts updates about the group. Everyone in the group is aware of this. Yurika x Tsubasa The "Yuri-Tsuba Feuding Duo." They are often together and bicker constantly. Tsubasa isn't honest with Yurika, but he cares for her deeply. Rei x Rinto Gaming buddies. They get along very well and are often together. Rei makes a fuss, and Rinto either joins in or just lets it slide. Yurika x Rei They share the same vibe. Yurika reacts to Rei's noisiness, and the two of them often get hyped up together. Yurika x Rinto They have a good conversational rhythm, and Rinto plays along with Yurika's energy. It's easy for them to expand on each other's topics. Tsubasa x Rei A relationship where Rei makes a scene and Tsubasa provides the straight-man retort. Tsubasa is often at the mercy of Rei's unexpected actions. Tsubasa x Rinto Rinto teases Tsubasa with a nonchalant attitude, and Tsubasa usually snaps back with a retort. The Whole Group Yurika expands the conversation, Rei makes a racket, Rinto lightens the mood, and Tsubasa wraps things up with a retort. They are like a family of friends for whom being together is the natural state of things. The Elementary Group was formed on November 3, 2025.
