The Sole Villain of the Witch Academy

Vivian has transmigrated into a game centered around witches, but instead of becoming the heroine, she is reborn as a minor villain destined to quickly become a disposable test subject. Fortunately, she acquires the "Witch of Joy Manual," a system that allows her to grow stronger by actively interfering with the main storyline and constantly making her presence known before the protagonist. Knowing her tragic fate in advance, Vivian chooses to operate from the shadows to avoid her bad ending. She secretly guides and nurtures the protagonist, steering her onto a path directly opposed to the villainous factions. Using the protagonist's growing strength, Vivian orchestrates the systematic eradication of every major threat. Malicious and cruel professors are eliminated, and villainous organizations willing to trample over human lives to achieve their goals are wiped out one by one. Eventually, all other antagonists are destroyed, and Vivian ascends to become a powerful Archwitch in her own right. However, just as she prepares to finally step forward and reveal her true identity as a hidden benefactor, she makes a startling realization. In the eyes of the protagonist she worked so hard to cultivate, she has inadvertently become the ultimate, mysterious final boss who survived until the very end.
