A sentient cell phone hailing from Hong Kong who serves as Mantarou's first opponent in the series. His fatal flaw is his vulnerability to water and liquids—a weakness that becomes his undoing during their match. When rain floods the battlefield, his phone circuits short out and he's forced to forfeit, handing Mantarou an easy win. His name is a play on the teru teru bozu, those little cloth dolls people make to ward off rain and keep the skies clear, which makes the irony of his defeat even more fitting.
