Suzumiya Suzune is a high school girl who loves her younger sister so much it’s unbearable. Despite this, she spends her days being treated coldly by her precious little sister, Shizuku. One day, her close friend tells her that Shizuku has recently been obsessed with a VRMMORPG called “Fantasy Frontier Online”. With her mind completely set on playing together with her younger sister, Suzune dives into the game world. She spends an entire night making an avatar that would appeal to her little sister’s preferences, a little girl with beautiful silver hair. For the sake of creating conversation with her little sister, she also chooses the same class as her, a magician. Preparations were complete! Or so she thought, but because she was a beginner, she made a mistake and misallocated her stats. Suzune’s character was now maxed towards ATK and turned into a joke build, the “Battlemage.” Completely ignorant of this situation, Shizuku gives her a condition, “If you get stronger, I’ll play together with you,” to which Suzune quickly accepts. “Wait for me Shizuku, Oneechan will definitely get stronger!” A little girl who’s a magician, yet her magic power was weak. Instead, she relied on physical attacks. Was it possible for her to really be able to convey her overflowing feelings to her little sister!? Later, she would be referred to as the “Bludgeoning Witch”, “Incarnation of a Real Life Cheat”, and “Bloodstained Little Girl.” Suzune’s slapstick game life starts now!!
