Akechi Mitsuhide
One year later in 1582, Katsunaga accompanied his father to Honnō-ji. Following the attack on Honno-ji and the death of Nobunaga, Akechi Mitsuhide attacked Nijō Castle, where Nobunaga's son Nobutada was staying. During the fight, Katsunaga was killed and Nobutada committed "seppuku".
