Servamp theory
You know, I was thinking. In chapter 23 of the manga (or episode 6 of the anime) Lawless tells Mahiru that eves have more physical durability than normal humans (really Kuro, you should have told Mahiru those things lol), but it’s never really explained how thats possible. Sure we know that if the servamp is drinking his eves blood they both become stronger, but Lawless didn’t drink Lichts blood. Than I remember the first arc. Kuro didn’t tell Mahiru about the lead. In the manga (chapter 5) he even called Lily a bastard for bringing that up and tries to convince Mahiru that it’s better to just pretend not to know about it. At that time i just thought he was a sloth and didn’t wanna bother. I mean Mahiru learned more about servamps and eves from others than from Kuro. But later we learn about the demons inside of the servamps. The demon who gave Mahiru his lead. A part of the demon is sealed inside of a rose, but also a part is in Kuro. Mahiru is attracted by the rose when he first sees it. He looks to be the only one who can hear the rose calling him in chapter 91. What if, in order to form a contract, the servamp gives a small part of his demon to the eve and for the lead he would get an other part of the demon? And thats why Kuro never had an eve to begin with and didn’t tell Mahiru about the lead? He didn’t want to talk about his past, so when an other brings the lead up, he is forced to give Mahiru what he wants, but to use it you need a demon. Why else would Mahiru be the only one who was able to hear the demon? Even Gear and Kuro didn't show any sign to hear the demon calling, and those two are supernatural beings. It would also explain why eve's die when they are seperated from there servamps. If the demonpart would try to return to the servamp if they are too far apart. The lives of the eves are not really bounded by the servamp, but by their demons
