Although the Spirit Tortoise has been decapitated, its familiar Ost remains alive and capable of reviving the creature at any moment. With allied armies needing to quickly regain their fighting strength, Naofumi executes a dangerous strategy. He ventures onto the back of the massive beast accompanied by only a small group. The objective is to identify and exploit the Tortoise's true weak spot before it can recover. This high-stakes maneuver is undertaken to neutralize the threat effectively while the broader forces regroup. The situation remains precarious as the enemy's potential resurrection looms over the battlefield.
