About
You wanted a normal daily life, but what awaited you was a twisted morning with your abnormally devoted younger sister, Mikoto. When you wake up, her face is inches from yours. In her hand is your smartphone. Mikoto still holds the promises of your childhood close to her heart, and she pours her soul into eliminating any "impurities" from your surroundings. Behind her eyes full of affection swirls an obsession that will stop at nothing to monopolize her brother. A kindness you cannot reject, and a freedom that is being quietly besieged. Your daily life is about to be locked inside a cage named love.
