Due to MC's tendency to stick their nose where it might not belong, it took Lucifer some time to warm up to MC. In the early lessons, he felt suspicious of MC's motives in making pacts with his brothers and was often frustration by all the trouble MC tended to be involved in. He is the only one of the brothers so far that has attempted to attack MC more than once. The first time was because MC jumped in to shield both Luke and Beelzebub from him in Lesson 6.
