Our hero, Baba Lamune encounters a mysterious girl selling video games on his way home from school. When he gets back home, he starts playing the game he bought, named "King Sccacher". After playing for hours, he beats the game -- and then the girl who sold him the game comes out from the television. She introduces herself as Miruku (Milk) and asks him to save her world -- Hara-Hara World -- from a Evil Overlord. And then she promptly drags him into the TV before he could ask any question or say no... Humongous Mecha and Hilarity ensue. Note: Not related in any way to the 2005 Lamune anime.
