Ultraman: Rotting in Jail in the Land of Light, with Belial as My Cellmate

The Cosmic Prison is an ancient place, personally built by Ultraman King. It holds the most vicious war criminals in the history of the multiverse. No one knows his real name. Everyone knows him only by his codename. Personally arrested by Ultraman King, the King of War, guilty of 160 grave crimes: Codename, Emperor. Today, the Cosmic Prison welcomed its second prisoner since its founding: Belial. “My name is Belial. I was imprisoned in the Cosmic Prison for trying to seize the Plasma Spark and overthrow the Land of Light.” “Though I was defeated and captured, I've always been curious about who has been locked up in the Cosmic Prison all this time.” Looking at the heavily guarded prison, Belial thought to himself. “My name is Yun Shen. I'm no war criminal. I'm just an ordinary transmigrator who got a System.” “Of course, I may have a few minor issues.” “But nobody's perfect. My issues aren't that serious. I just don't like any species other than humans.” “So I clear out heretics from time to time.” “Speaking of which, is that Belial? He looks pretty lively.” Looking at Belial in the cell next door, Yun Shen suddenly became interested.
