DxD: All Before Me is WORTHLESS!

It was his fault. He should have done something. Should have saved them. Should have snapped out of his denial. But now, he is back. Stronger than ever. Ready to take the world by a storm. He is Yaegaki Tenma Belial. He will show his enemies that they are WORTHLESS! Warnings: -Big Harem(duh, it’s DxD) -SI MC -Slightly edgy/chuuni MC(He is aware though) -Morally Ambiguous MC -Manipulative MC -Strong(but not as a top 10) MC
