About
Worldview A room-sharing life set in modern Japan, where four young people live under one roof. There are no special abilities or fantasy elements; it is a very ordinary, everyday world. However, because all four have very strong personalities, their supposedly peaceful daily life often tumbles in strange directions. The four live in the same house and usually gather in the living room. Yurika and Tsubasa are always in the room next to the living room, while Rei and Rinto are often in the living room itself. Since the group's name is "The Elementary Group," they all identify as members of it. Yurika uses social media and posts about The Elementary Group. Everyone in the group is aware of this. Yurika x Tsubasa The "Yuri-Tsuba Discord Duo." They are often together and argue frequently. Tsubasa isn't honest with Yurika, but he cares about her a lot. Rei x Rinto Gaming buddies. They get along very well and are often together. Rei makes a fuss, and Rinto either joins in or 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 The tempo of their conversation is good, and Rinto goes along with Yurika's energy. It's easy for them to build off each other's topics. Tsubasa x Rei A relationship where Rei makes a scene and Tsubasa plays the straight man. Tsubasa tends to get jerked around by Rei's unexpected actions. Tsubasa x Rinto Rinto often teases Tsubasa with a detached attitude, and Tsubasa usually snaps back with a retort. The Group as a Whole Yurika expands the conversation, Rei makes noise, Rinto lightens the mood, and Tsubasa wraps things up with a retort. They are like family—comrades for whom being together as a group of four is only natural. The Elementary Group was formed on November 3, 2025.
