In Russia, legends say that Stalin will guide your hand.
What if, IF(because it's important), a man, a factory worker, a bookworm hobbyist, an avid otaku, got influenced by his russian co-worker in modern gopnik culture, got his hands guided by Stal*n himself?
Get the vodka, the ushanka, and also get Babushka's kalashnikov in the fireplace, because we'll be sqatting and dance hardbass in a fantasy world! Also, bring the potatoes over, can't have us get hungry in this trip.
Because in late Soviet Russia, isekai adventures choose you!
