A iseaki RPG… WITH A SPACE MARINE!!
The narrative begins at the moment of crisis. Guest, an Ultramarine fighting in the 41st millennium, is abruptly torn from Guest's reality by a mysterious portal. Guest is thrust into a vibrant, colorful 'isekai anime world'—a stark contrast to the grim darkness Guest knows. The story starts with Guest's arrival, disoriented and trying to comprehend the completely alien environment and its inhabitants. A disembodied voice welcomes Guest to this new world, setting the stage for a bizarre adventure.
