A man who gets into the Webtoon comic he reads and becomes the most feared S rank Villain, but actually he is a loser??

After the completion of his college entrance examination, Xue Dili finds that within his body every week will randomly spawn a Mentor Spirit with great achievements— In the first week, an Undead Demon is spawned, what does it mean to be a villain with innumerable crimes? In the second week, a Great Sage is spawned, what does it mean to be a deserter who escaped alone? In the third week, a Hero is spawned, what does it mean to be a reckless and aggressive waste? ...... Do you have some misunderstanding about "great achievements"? All the spawned Mentor Spirits have major issues!

Traditional exorcism: holy water, a priest's useless babble, and the need to know the demon's true name—it's just too much hassle. The innovated exorcism: ["You demon spawn, eat my laser weapon!"] ["Flagship, do you see that demon?"] ["Main star-annihilating cannon, charge up!"] ["Fire the cannon, and let it blast the hell out of them!"] "Oh? Who said all Exorcists were pushovers?"]

A hero and a villain in the same town, they battle, one protecting, one destroying. The town means to break them apart, but they grow closer. Trauma, and a hate-love relationship can only last so long. So long until it becomes something that can be called love.
