Fate: I Died Four Times in a Row from the Start

Nangong Meng was a transmigrator who unexpectedly gained infinite magic power and a talent for mastering magic. She should have had an unbelievably lucky start, but instead she got a script with a disastrous opening. The first time, she fell into the barren world of Kabaneri of the Iron Fortress. There was no magic here, only bloodthirsty Kabane. Despite possessing peerless magical power, she had nowhere to use it. She struggled to last ten minutes in the wilderness before falling to a swarm of monsters. When she awoke again, she was in Hope's Peak Academy from Danganronpa, where she discovered a third ability: after dying, she would transmigrate to another world. But there was still no place for magic here. The so-called "graduation requirement" was to commit the perfect murder. Nangong Meng was naturally naive, and readily accepted a drink offered by a certain "Super High School Level Chemistry Genius". Once again, her life came to an end. The third time she opened her eyes, she had fallen into the curse-ridden Heavenly Host Elementary School. Although supernatural forces existed here, it was a cursed place overrun by ghosts. To make matters worse, she appeared right in front of the ultimate vengeful spirit, Sachiko. Without even a chance to struggle, another defeat was added to her transmigration record. The fourth time, she found herself on a battlefield torn apart by war. As she looked around in bewilderment, she suddenly saw the Astartes rushing to reinforce the battlefield. Without hesitation, Nangong Meng picked up the weapon of a nearby fallen Guardsman and ended her own life. It wasn't until her fifth transmigration that she finally reached a somewhat better world: the Nasuverse, where magecraft and the mystic coexist.
