Saiyuuki Gaiden

Long before the legendary journey to the west, four extraordinary beings once walked the celestial realm as gods. Though divine in nature, they were far from perfect—each carrying human flaws and desires that set them apart from their ethereal peers. Among them, a wild and untamed spirit named Goku finds himself at the center of growing tensions in Heaven, his unpredictable nature and immense power drawing both fascination and fear from the other deities. When the heavenly authorities decide that Goku poses too great a threat to remain unchecked, three unlikely allies emerge from the ranks of Heaven itself. Konzen Douji, a noble with a rebellious streak; Field Marshal Tenpou, a brilliant strategist with hidden depths; and General Kenren, a fierce warrior with his own code of honor—each see something worth protecting in the young god. As the celestial hierarchy turns against them, these four kindred spirits must navigate the treacherous politics of Heaven while forging bonds that will transcend their divine origins. This prequel story explores the ancient past of familiar faces, revealing how the choices made in the celestial realm would echo through the centuries to come.
