After Transferring to Black Sakura, I Became the Evil Cub?

Introduction: After traveling through time, Jiang Xiaobai discovered that the job-changing NPC in the job-changing dungeon was actually the Master from the Five Holy Grail Wars! The students flocked to Illya and Rin Tohsaka who were ranked at the top, but they dismissed Shinji Matou at the bottom! Only he knows that Matou Shinji also has a darkened sister who almost broke through the five battles... After transferring to Black Sakura, Jiang Xiaobai felt that something was wrong with him. Just because someone took one more look at him in the crowd, that person's eyes exploded. Of course, this is nothing at all, as long as an individual can explode. The truly outrageous thing is yet to come. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
