Byakko is the second of the Four Beasts, a large tiger demon who can absorb reiki into his body to make himself stronger. He battles with Kuwabara twice -- first on the battlements of the Saint Beasts' castle, where Kuwabara defeats him by overstuffing his body with his own reiki, and again in his own lair, falling into the lava and apparently dying. He reappears once more, begging the third Saint Beast Seiryu for help; however, he is frozen by his Seiryu, his fellow Saint Beast and shattered into shards of ice, an ignominious end to his life. Lower C class demon.
