Heihachi is an ordinary mobile game addict who spends far too much on gacha pulls. One routine roll gives him an item that sends him into another world, and his smartphone comes along with the game's gacha still working. When monsters attack and he has no other options, he falls back on what he knows and rolls again, only to watch a summoned unit take physical form in front of him. The app turns out to be a cheat tool that can produce gear and beautiful girl characters, among them a skilled fighter named Norl. His new goal is to assemble the strongest army of beautiful girls in this world. Expect a fantasy adventure that mixes action and comedy with ecchi and romance.
