Turning back time a little, after Lilith left, Ein was fighting the endless waves of skeletons continuously. With each swing of the two blessed swords, a group of skeletons would fall to the ground, never to stand back up.
The sight of Ein standing in the midst of thousands of skeletons was epic. He seemed like a hero fighting against the army of evil... which wasn't that far off from reality.
The only problem for Ein is that he's a human being through and through. Even if he reinforced his body with mana, his stamina still had its limits. Sweat continuously perspired from his whole body, making him feel extreme thirst. Added to that, it was hard to protect himself from all directions, even if the enemy's attacks were extremely simple swings without a hint of skill.
'Lilith! I think it's about time!' He thought after every other minute that passed.
