Takuto is a flirtatious 14-year-old human boy who becomes one of Mint's two chosen companions after her arrival on Earth. He forges their initial friendship by helping Mint locate her Aunt Herb's "Happy Shop" when her father neglects to provide the address. Despite his extreme vertigo occasionally complicating their adventures, Takuto displays quick thinking and resourcefulness—evidenced when he aids Mint in evading police and spearheads a "great detective operation" to resolve a group challenge. As a trusted ally, he learns Mint's secret identity as a princess from a world of dreams and magic. Wielding a transformation-granting magical pendant, Takuto actively supports her mission to restore hope and dreams on Earth, using his abilities to overcome obstacles throughout their journey.
