Angelic Layer: Hatoko Kobayashi

She is Misaki's best friend and Angelic Layer mentor. Even at a very young age, she is intelligent, mature, and hard-working. She is an expert at Angelic Layer, often winning her games in mere seconds. She wins all ten of her games at the Tokyo prefecture games, and is the defending champion of the Kantō regional games. She is fiercely competitive, and often works to increase her angel's speed and power. She likes to poke fun at her brother Kotaro for his apparent ineptness when it comes to his crush on Misaki. Hatoko treats Misaki like her student rather than her nee-chan (sister). Hatoko's angel is Suzuka.
