The strongest dungeon streamer Haruka had his life ruined after being deceived by others. Then, suddenly, he finds himself 10 years in the past.

This time, he's going to live for himself.

Knowing just how powerful he is and armed with knowledge of the future, Haruka sets out to become a viral sensation as a dungeon streamer. When a beautiful streamer who is destined to die is attacked by a terrifying unique monster, he'll save her—and stream it live!

He'll recruit the world's greatest blacksmith before they become famous, rescue a highly talented spirit user who looks like a little girl but is actually an older woman, and buy up useful items before their value becomes known—then make a fortune streaming how to use them.

Even land where dungeons haven't been discovered yet? He'll buy that too.

Using his knowledge of the future, he'll turn everything into content, become the strongest streamer, and save people who would otherwise suffer unfortunate fates.
