Maro is a popular virtual YouTuber active on the RyuTube platform, where her channel quickly gained over one million subscribers. She serves as a messenger of the Dragon God and acts as a guide and supporter for the heroes Wataru and Kakeru during their adventures in the parallel world of Chubukai. Despite her cute and somewhat innocent appearance, she possesses a cheerful, natural, and slightly whimsical personality. She can breathe powerful flames from her mouth when needed, and she is often accompanied by a small long-tailed tit named Uzume, who helps with filming for her channel. When Maro pets Uzume three times, the bird transforms into a rice‑cooker‑shaped helper called Uzume Maru that can absorb blocks and create useful items. Maro is later revealed to be Amaterasu, the sun goddess and a member of the ruling pantheon known as the God 7, which governs Chubukai. She has a younger brother, Tsukuyomi, whom she affectionately calls Tsukku, and another brother, Susanoo, nicknamed Sussa. She gives friendly nicknames to the other God 7 members as well. Her primary motivation is to support the saviors in their mission to defeat the antagonist Enjoda and restore peace to Chubukai. Throughout the story, she remains a steadfast ally who sometimes serves as a pinch‑hitter for the Dragon God, providing guidance, comic relief, and crucial assistance during battles. In a later crisis, she is brainwashed by Enjoda, but the combined power of her friends’ smiles and Wataru’s determination frees her. Her abilities include her fire‑breathing, her Vtuber persona that helps rally public support, and her divine nature as a sun goddess, though the full extent of that power is only hinted at. She forms close bonds with Wataru, Kakeru, the swordsman Offline, and the other gods, and her unwavering cheerfulness helps keep the group’s spirits high even in difficult moments.
