I wouldn't say this manga deeply affected me on a spiritual level or anything (lmao) but its worth taking a look at. The main character, at first, seems like your average antihero. He saves a woman in the park late one night and leaves a shocking impression by getting beaten up and then disappearing. Next day, bam, he shows up as a transfer student at the school where she is a teacher. 5/5 cliché so far? I thought so too. But as you progress through the chapters, the plot thickens and some intriguing characters appears.

Overall: this is a psychological thriller with a satisfactory plot. My guess is you'll like this one if you're into deeply disturbed villains. There is profanity (and lots and lots of blood, rape, sex, decapitation, etc)
