(Disclaimer: The following infomation isn't real. The school doesn't actually exist and the events are just fictional.)
Ikari is a japanese student and lives a pretty normal life. She is 17 years old and has long black hair. Her eyes are coloured red and she seems cold at first, but is actually a sunshine.
The school she is going to is located in a small city of Japan called Shibaba and is called Akuma High.
She is walking down the hallway, in direction of her locker, as she gets distracted by the sound of falling boxes. Ikari follows the noise which leads her to a storageroom. She walks in, wanting to put the boxes back on the shelf, but as she grabs the first box she gets hit in the back head and faints.
That was the last time Ikari was present in the human world. And everything started to change.
It is late and Ikari hasn't returned. Osore, her twin sister is worried and looks out the window, waiting for her to return. Osore is a little younger than her sister and has red, short hair and black eyes. She and Ikari are very close and hang around with each other the whole time. They usually go home together too, but Ikari had to stay longer at school and Osore returned alone.
"Osore, come and have dinner.", says her father to the girl while sitting down. Osore tells her father: " Ikari hasn't returned yet. Where is she?" "She's probably still in school. You know how she is; stays in the library to study until late in the night. Don't worry, she'll be fine." "I guess you're right.", replies Osore as she sits down a the table as well.
The next morning as Osore wakes up, she looks in her sisters room to check if she's there, but no sign of Ikari. Osore walks in to the kitchen finding her parents eating breakfast. "Where's Ikari?" "She hasn't returned home since yesterday.", answers her mother. "We already called the police and they are searching for her.", adds her father. Osore is worried and doesn't say anything at this morning. After she gets ready, she goes to the school and searches for her sister. She tries to call her multiple times, but she doesn't answer. She tries and calls her once again. As the call begins, Osore hears a ringing from a phone and follows it. She gets in to a storage room with boxes lying on the ground. She puts the boxes on the shelf and sees Ikaris phone under the boxes. Osore can't believe it. She takes the phone and puts it in her pocket. The school bell brings her back to reality and she goes to her classroom.
After class she goes to the cafeteria and eats lunch. After she finishes her food, she still has some time left, so she takes out her sisters phone and looks at it. She notices a note at the back of it. The note says:
Don't worry, Ikari is in good hands.
She has been chosen for an exchange program from the three worlds.
She's now in the Devildom and will be back in one year.
~ From Diavolo himself
"The Devildom?", Osore thought to herself. "Does that mean she's in hell? Is Ikari... dead?!", thoughts that get through Osores head are making her mentally crazy.
After school she goes straight home and showes her parents the phone with the note. The family brings the things to the police and the officers tell them, that it's just a prank from the kidnappers, but the family doesn't believe them.
Osore diary: " Is it true, Ikari? Are you in the devildom? Is it bad there? How are you doing? You will come back, right? Promise me that you'll come back as soon as you can. I miss you and I love you, my dear sister!"
