Attention Mods: How to completely restart your game progress?

[KazehayaYuuki]

Hello mods
I want to reset my game progress to start (back to dawn and level 1)
It's doesn't matter if my in game purchases are lost, I just want to start over.
I didn't connect my game to any icloud game center or backups or facebook

Can you help me please as fast as you can? thanks
