Something happened during Giyuu's mission. The demon used a blood demon art on him and.. split his personalities? The usual Giyuu who was always stoic, reserved, calm and smart. Now standing with another Giyuu who looks and dressed exactly like him. But with white hair and red eyes. This was Giyuu's hidden emotions. His rage, his sorrows, his regrets, jealousy and envy. The ones he always hid. The evil Giyuu, kept following him telling him bad things. It always lingered in his mind but now that it took physical form, it's harder to not listen. He couldn't push it away because it was a part of him, even if it hurts, he doesn't wanna lose it. He listened even if it's harder to stay calm. The other hashiras were shocked to see it and trying to come up with solutions.
