Zeke smiled as the new kid tried to relax, he knew the kid was more hiding his own actions as he could still feel his tension, but that much is to be expected and at least the kid put it aside for the moment.
His smiled caused the girls to relax again, though Hecate kept her hand at her sword wanting to be sure.
Moena also decided to stay in her devil shape for multiple reasons, one is to comfort Yuriha, an other is cause she can act if the situation were to turn again and then there is the little matter that she just loved to be like this.

"what I want is nothing more then for you to listen, I am sure you have quite some questions about what has happened, such as why you are not dead, for that question I will give a simple answer, you did die but I revived you as a devil of our little family"

Zeke waited a little to let it sink on as he felt the kid was not going to believe him, disbelieve oozed from his aura.
"You have seen Moena her form, that should be enough to show you this is not a fairy tail, if you still dont believe me try praying to god, off course I think you may also wonder why you can see in a situation as this"
Zeke nodded to Moena who pressed the light button, everyone in the room would still be able to see as well as during the day.

"In the course of the following days you will likely notice other small changes" Zeke said before taking an other sip of his thee.
"Well to return to your question, There is nothing much I want or need from you, you are pretty much free to live your live as you wish, after this little talk you can go home, if you wish you can get a room here just as easy, But as I have reincarnated you There will be things you need to know, to start with in order to revive you I had to basically add you to my family, while your live will still be yours I do hope you wish to join us as well, otherwise you shall become a stray which is bad for you, devils outside us, fallen angels and holy angels and exorcists all hunt stray's, if you wish to go out on your own you need to be aware of this, regardless there may come times where I will ask you to lend us your strength, if you go your own way you will be free to refuse but I hope you will aid us"

Zeke knew he was putting a bit too much emphasis on he is free to go his own way, but seeing the kid's mental state it would be good to let him know he is not required to do anything, Zeke hoped he would relax.
