Waking Up To A Broken Engagement, I Instantly Turns Into A Mad Dog

Opening his eyes, Jeremy discovered he had transmigrated into a strange magical world, becoming a cannon fodder villain of the exact same name.
In this world, the power of mages stems from the Covenant connected to the gods. Usually, at the age of 16, each person undergoes an awakening ritual for the Covenant Rank bestowed by the gods, and simultaneously receives their corresponding natal Holy Artifact.
Jeremy's Covenant Rank was even lower than the lowest level of the awakening pillar, and because of this, his engagement was broken off...
Asleep one second and dumped the next, Jeremy instantly turned into a mad dog, biting whoever crossed his path.
And Jeremy didn't just go crazy alone; he dragged a whole bunch of geniuses into madness with him...
In less than a year, Jeremy—labeled as a mad dog—had become a celebrity at the aristocratic academy.
As for Jeremy's teammates...
The lazy, sharp-tongued aristocratic young master: “Just randomly pick a bad day to go, that way the bad day will turn into a good day.”
The cold-faced little princess quietly hid the freshly dissected corpse, using the corpse's blood to nourish the flowers.
The crazy stalker, innocent on the outside but dark on the inside, narrowed his eyes and smiled: “Whoever dares to compete with me for the captain deserves to die~”
The gloomy male student who never spoke a word: “...”
Facing this bunch of lunatics, Jeremy coldly expressed: “When it comes to madness, I consider myself inferior to you.”
Everyone fell silent: “... How about you put the knife down first?”
