Plot
Two mad scientists, Professor Ichiroubei Hiragi and Count Collection, simultaneously manage to open a dream hole to an alternate world where myths are real, the Sixgate world. Professor Hiiragi recruits his daughter Rokuna Hiragi and her friend Mondo Ooya to become the Mon Colle Knights and help him in obtaining six magical items before Count Collection does. When the items combine, they have the power to alter the dimensional barriers, allowing whoever claims the items to be used peacefully between worlds or reformat reality for worse.
