Trivia / Go, Go, Loser Ranger!

• All-Star Cast: The anime adaptation features well-known names such as Yūsuke Kobayashi, Yuichi Nakamura, Kosuke Toriumi, Kensho Ono, and MAO, amongst many others.
• Acting for Two: Kensho Ono voices Yellow Keeper and Aran Hekiru.
• Casting Gag: Both Yuichi Nakamura and M·A·O, who voice Red Keeper and Pink Keeper respectively, were previously casted as heroes in the Super Sentai franchise^note Nakamura previously voiced J/Stag Buster in Tokumei Sentai Go Busters. M·A·O played Luka Millfy/Gokai Yellow in Kaizoku Sentai Gokaiger and Raptor 283/Washi Pink in Uchu Sentai Kyuranger.
• What Could Have Been: Negi Haruba occasionally shows off prototype designs of the characters. Some didn't change much, but Hisui had a more emo design and makeup, while Hekiru had longer hair.
