Ashita no Tsumibito to Mujintou no Kyoushitsu

In a society where computers determine an individual's future, a boy named Yuhi Touji is labeled as a "sinner of tomorrow" and sent to Tetsumado Island, an isolated location where twelve others with the same designation are gathered. Their task is to spend a year together, attempting to prove they are not destined for wrongdoing. As time passes, the hidden aspects of their personalities begin to surface. The situation grows complicated as the group navigates their time together, raising questions about whether their experiences will lead to personal growth or further descent into darkness.
