One Way Road Lucifer

Bullied and mocked by his family and treated badly by his classmates for something he did not do, and even goes out of his way to protect them with his life, he wonders why he even lived in the 1st place. Suddenly given a second chance in life, he will live how he wants to and try to become the strongest so no one will bully or mock him again. Issei x Harem, OC x Harem (possibly)
