"Today is your thirteenth birthday be ready for the party after school" A woman announced to a girl finishing up her breakfast before heading off to school.
"Oh really well I bet this will be interesting" the girl grinned. Her family had a habit of changing themes for the birthday party. No one theme was used more than once every four years.
The girl was almost a much younger image of her mother.
Her hair was chestnut brown with a crinkle cut style and put in a low ponytail. Her eyes were green and her skin was lightly tanned. Her uniform for school was simple. A dark red blazer with a light grey lower thigh length skirt over a white dress shirt with a black bow tie, black stockings and brown loafers. She grabbed her black backpack and ran out the door heading to school.
Despite her slightly small frame she was able to run really fast, making it to school in record time. The girl's name was Kurumi Torikago. She was in Hidden Valley Junior High school, soon it would be her second year there.
Once arriving at class, she sat her bag in the chair at her desk and got ready for the day.
The thirteenth birthday of a child is special. Many mysterious things are said to happen on that day. some say it is the start of adulthood where you act strangely in response to being one year closer to becoming an adult. Some act in denial of it and act childishly or try to stand out from the crowd also known as "Chunnibyo" by the Japanese. But the people in the city of Ivory Valley gain Guardian angels when they turn thirteen. The original reason has been long forgotten, and is believed to be that thirteen is the age when demons can corrupt or attack humans.
All demons and Angels have human forms that appear unrealistically attractive. The angels all typically have pastel colored wings halos and hair. Demons typically have dark colored horns, tattoos, and if any wings they are also dark colored.
As such humans are gifted with guardians to protect them only the human being protected can see the angel and the protection is only needed until the human finds love in which the demons usually give up their attempts and move on to the next possible victim.
Usually when that happens the human forgets they had a guardian angel and assumes they had a rather interesting teenage life and move on in "blissful ignorance".
Kurumi Torikago had went through her school day wondering how her party was gonna go. She didn't buy the nonsense about Guardian angels that was just ridiculous. Now on her way home she started guessing what kind of gifts she was getting from her family. It was just her mom, brother, grandmother and occasionally if he thought to stop by, her father. Her mother and father had been divorced since her younger brother Kinta turned three. He was eight now and soon to be five years younger than Kurumi. She pushed the gate open and was bombed with a surprise party. something she hadn't expected as her mother told her that morning that they were holding a party. but now that Kurumi thought about it she realized her mother hadn't stated what kind of party.
Kurumi smiled knowing she'd been outwitted and joined the festivities. the worry of some mystical event happening long forgotten.
