Gantz, Jisatsutou Recommendations
Kid that nobody really believes in steps up. In Gantz a bunch of people have o fight aliens in almost like an alternate universe and kei is the leader.The story has a lot of gore, there's rape, it's mature but very good. In Jisatsutou Sei is a nobody who attempted suicide, sent to an island with other attempted suicidal people, and uses his kick ass archery skills to survive. It's very good as well.
