Taro is the younger brother of Adell, the main protagonist of Disgaea 2: Cursed Memories. He and his sister Hanako were born demons, due to her parents being turned into demons by Overlord Zenon's curse. Soon after Rozalin is summonded to the village, Taro begins to admire her, refering to her as Princess.
Taro is cowardly and sarcastic, yet he is able to muster up enough courage to help out his older brother Adell. Although his sister Hanako constantly picks on him, he'll join her in poking fun at Adell.
He was released as a DLC playable character in Disgaea 3: Absence of Justice.
