As Long as You Are in the Second Grade, You Will Become Stronger

A male protagonist who is incapable of emotions, and a system that requires you to become stronger in the second half. In this world full of wonders and crises, we must also face everything with laughter. The devil from another world, the succubus following you closely, urban legends full of conspiracy... All of this was saved by an emotionless middle school boy. For the record, the male protagonist is a college student, so he can't save the world. But it can easily save the universe.
