Suzuya Suzune, a high school girl utterly devoted to her younger sister, spent her days being treated coldly by Shizuku, the very sister she adored.

Then one day, she heard from her best friend that Shizuku was hooked on a VRMMORPG called "Fantasy Frontier Online," and with a burning desire to play with her sister, she dove into the game world.

She stayed up all night to create a silver-haired, beautiful young girl avatar tailored to her sister's tastes, and chose the same "Magician" class to better connect with her sister. Her preparations were perfect!

Or so she thought, but due to a beginner's mistake, she misallocated her status points, and Suzune's character had transformed into a meme-build focused entirely on ATK: a "Brawling Mage"!

Oblivious to her predicament, Suzune readily accepted Shizuku's condition: "If you get strong, I'll play with you."

"Wait for me, Shizuku, Big Sis will definitely become strong!"

A little witch, weak in magic despite her class, fights with physical attacks and dominates the game world, her heart brimming with overflowing love for her sister!!

Suzune's chaotic game life now begins, a life that will later see her known as the "Bashing Witch," "Embodiment of Real-Life Cheats," "Blood-Soaked Loli," and more!!
