Magical Girl and His Infinite Sword System

"This power that should be used by all mankind will only be used by you." A "perfect" Shirou who experienced multiple fate lines in the Fate world fell into a strange world called Mitakihara City due to the shock of time and space. There is no Holy Grail War or Magic Association here, but it is filled with twisted monsters called "witches" and a group of magical girls fighting against despair. In this world, although Shirou's total magic power reaches B+ level, which is far higher than before, it is still insufficient when facing the Witch Night that can destroy the city. However, when he was on the verge of a desperate situation to protect others, the "dream call" sleeping in his body would awaken - a red and black battle suit was added to his body, his magic power surged to A+++ level, and the divinely-made weapons were projected without any side effects... But the price was that after the battle, he would fall into a month-long magic depletion period, and he would be so weak that he could not even project a knife. Madoka Shikame's tender care, Tomoe Asami's elegant dependence, Miki Sayaka's fierce possession, Sakura Kyoko's forthright protection, Akatsuki Homura's paranoid control - the five magical girls gradually became addicted to this unique "salvation" through Shirou's rescue and sacrifice. Their gratitude turns into obsession, and their dependence turns into pathological possessiveness. "You are my light... Never want to leave." "If you dare to fight for someone else, I will kill that person first." "Your life has long been my property."
