Lucifer attacked the monster relentlessly, only for it to regenerate and attack him back. Luckily he had gotten a catalyst from the ethercraft researcher's room that could hold an immense amount of ether inside, that was the only way he could carry on with the fight.
A strike came from his left, he jumped back instead of blocking. He felt air moving around behind him, he could not take his eyes off the monster, but he took a quick glance.
It was Clara, who was sleeping, he had forgotten about her. He instinctively put a shield in front of him, deflecting a rather stronger blow. Now he also had the girl to think about, his master had only told him to kill the man, not the girl.
He jumped to the side, cutting the monster in half vertically with the wind. He was trying to get the monster's attention, and luckily, he succeeded. The monster turned to him instead of the girl.
