Normal P.O.V
Lucy was shocked but not has much has Rin because he knew what Satan was capable of
''S-Satan's mark, what does that mean hat man ?'' asked Lucy
''When Satan dies he can choose an heir, normally is one of his sons but he didn't wan't to do that, so he choose from another world, since a baby, but the persons true nature only wakes up a time after Satan dies, and now you have Satan's powers and that mark is the proof'' Both Rin and Shiemi were with their eyes wide open
''Then what's going to happen with Lucy ?'' Rin asked worried
''All the demons will problably come after her, and make her the Queen because she has the same source of power of Satan and she's also the heir'' said Mephisto really calm but at the same time fun
''I understand that, but I can't be queen so quickly, I still don't remember about my past and I-'' Lucy was cut of by Rin
''Don't worry Lucy I, We will protect you till you know what you are going to do and get back your memories''
''Till then she can stay in our school and our club ?'' said Shiemi with a sweet smile
''I guess we can always open up a place for fun!'' said mephisto after turning into a dog again and going away
''I'll never get used to that, but Rin can you tell me more about this place and what are all of you ?'' Rin explained to Lucy all of it, that he was a demon and also an exorcist he told her about his brother, the school, everything and she also stayed friends with Shiemi that also gave Lucy a nickname
''Are feeling better Lulu ?'' asked Shiemi in a sweet voice
''Yes, thank you, oh and do you guys have something I can dress ?''
''Since you will be attending our school you will have to wear our uniforms'' said Yukio entering in the room with a uniform on his hand
''Yukio-senpai !''
''how did you knew that Lucy was here ?'' asked Rin
''I Passed by Mephisto while I was in the hallway and he told about everything,its Lucy Right ?''
''Yes, thanks for the uniform, hum...'' said Lucy
''Its Yukio Okumura but you can call me Yukio, You will be living in the same dormitory as us from now on, welcome to our school Lucy '' said Yukio with a smile on his face they all started talking with Lucy and Explained her the danger of the demons, How were her classes till was already late
''Oh, it's already 7 p.m , I'll have to go now to make dinner see you tomorrow at school, bye Lulu''
''Bye Shiemi'' answered Lucy and the Okumura brothers just smiled at her
''Ok so we will be waiting outside for you to dress up'' said Rin going outside with Yukio leaving Lucy alone .

Lucy P.O.V
So Im a demon just like them huh, does that mean that I'm also evil like the ones they told me about ? No that can't be they are so sweet lets say different kinds and I can't forget that they are also half human, where was your head Lucy, I finished dressing up and went to see me on the mirror, eheh you can say I have some sex appeal but, this mark on the neck, I can feel something bad coming
''Lucy so are you ready ?'' said Rin entering in the room without asking
''You pervert, you can't enter in a room while a girl is dressing up'' I said, what a perv, I must be careful from now on
''But you are already dressed'' said Rin
''Even so, you can't''
''Anyway, Lucy are you ready for what might come and your new home ?'' said Yukio and both of them gave me their hands and I went with them, this is my new start.
We finally arrived to a building and we went to the cafeteria because me and Rin were really angry but in the contrary Yukio went to his room
''Humm this is so good was it really you who made this ?'' I asked
''Yup, I have big skills in making food '' said Rin
''Oh Rin by the way what's that big thing, that you are always carrying''
''This is my Katana I use to kill demons, and Yukio uses two pistols everyone has different types of things to kill them'' he answered If I have powers maybe I have one too right ?
''What about me do you think that I may have something ?''
''When me and Yukio were outside waiting for you he talked something about a weapon you have that only the heir can use in this case you, I can take you there if you wan't'' Then I really do have one what is that weapon I have to find out

''Please take me there !''

Normal P.O.V
Both Rin and Lucy went to a forest were the weapon might be they were walking when they suddenly heard something
''Get down'' Rin grabbed Lucy and was now in the floor under Lucy, they were so close to each other that Lucy was already blushing, Lucky her it was night and Rin couldn't see her face that good, in a minute later a lot of demons appeared and started attacking them, Rin put out his katana and was now killing, this was the first time Lucy was seeing his flames
''your flames are beautiful'' Lucy said whispering to her, Rin pretended that he hand't listened to that and continued killing them with a slight blush on his face.
Rin finally killed those demons and they both entered the place it was like a rookie house , and there after searching a little, they found a whip, Rin was going to gave you the whip and suddenly a voice come from outside
''I knew this would end happening, just save that whip well you will need it later, probably...''

Its awful I know, and I'm sorry I took so long really!
