chapter 2: A fragment of the past

Y/n's pov:

I struggle and manage to open the big door, i took a look inside the castle and all of them is white but detailed which the walls have wings, a sphere for some reason but i see another door as i step in.

Y/n: what is this place? Hello?- i speak searching for anyone while approuch the door and try to open it but was no use- great, looks like i came here for nothing - i sigh and turn around to see a black coat figure standing the door i when - !!

Y/n: who are you!?

Black coat figure: .... Your wondering why are you in this castle Roxas? - the female figure spoke questioning to him-

Y/n: Roxas? Who's roxas? Im Y/n, where am i? Why am i here?- i respond with another question-

Black coat figure - pulls out a Card and throws it at him - use this.

Y/n: - grabs it and looks at the card- whats this? A card??

Black coat figure: 7 floors; 7 Sins that hold your past, use the cards i manage to craft of your other memories Roxas, you must regain them...you must...- before she could finish, she vanish-

Y/n: Wait!! - i rush towards the figure but was too late- damn it....- i look again to the card and look to the door- who is Roxas? - i slowly approuch the door and raise the card up which it glow at same time the door begins to open and slowly enters it-

- meanwhile with Mashu-

Mashu's pov:

I was walking to the nurse room to check on Y/n, when i enter i see tamamo cat sleeping on the floor by his side like a dog or cat that stays with his/her owner side.
