IMPORTANT AUTHOR'S NOTE PLEASE READ
Ok so it's been a while and I've decided to add and change a few things to the story which is why I am once again rewriting what has already been published. I'm adding a couple ocs which is a new concept for me but I decided to try it because I've decided to write the events that occur from when Hotaru leaves Cross Academy to when she returns and I have outlined a lot more things to expand on the characters and their relationships. AOS is still going to end as a HotaruxZero story but there is going to be another surprise pairing for Hotaru that I am actually really excited to write.
So the new timeline for the story is:

Prologue

Rido Arc (set in Cross Academy)

Mahoutokoro Arc (set in Crystal Tokyo)

Blood Puppets Arc (set in Cross Academy)

The World is Grey (set in Cross Academy

Nemesis Arc (set in surprise location)

Epilogue

Now on to the short snippet

Purple is an unnatural hair colour for a human. But Zero guesses that she isn't really human after all. It wasn't the purple colour that he imagined when he was first warned that Hotaru Tomoe had purple hair. It's a dark purple, and in the dark away from direct light he could almost imagine it as black. It was unnatural. But that's why it suited her.

Hotaru was an anomaly. An enigma. And it was obvious she got some amusement out of it. She never tried to hide her colouring in fact it could be said that her hair was one of her favourite features as she was always playing with it. That didn't mean it didn't hurt her when people said that it was weird. That she was weird. But she would always shake it off moments later.

He asked her about it once and she gave him a smile that he had never seen on her face before. It was soft and her eyes had a nostalgic look.

"Someone once told me that they liked the colour" was all that she said on the matter lost in memories.

"I really like your hair Tenshi it's such a pretty colour."
