Takakage Kobayakawa is Motonari's third son who was adopted into the Kobayakawa family at an early age. After Motonari passed away, he and his older brother, Motoharu Kikkawa, were responsible for Terumoto's upbringing. Takakage was the particularly harsh and stricter guardian of the two. Although he could have been severely punished for his actions, Terumoto appreciated him and saw him as his father figure. He had no children but adopted two, one of which includes Hideaki.
