The conversation between Kenji and Principal Val was interrupted by the furious student council girl named "Sly", Sly was actually the Principal Granddaughter, she was kind, cheerful and beautiful girl but one day that expression change when her parents died on an accident even Principal Val cannot predict, it was the Ice Dragon that rule ove North of Aetheria that kills her parent and it was the one of the strongest dragon in Content of Zou.
Kenji whisper and ask Principal Val how he manage to take care of Sly if she had her trauma cause of her parents death and how Sly handle that trauma.
Principal Val reply to Kenji question.
"Oh oh, I raised Sly like my own daughter and I give all of my attention to her so that she cannot remember her trauma to her parents accident."
And the Principal Val ask Kenji if Kenji wants to protect Sly cause he is the Grandson of the Great Aetheria and become Sly fiance.
Kenji accept the request of Principal Val when Sly overheard their conversation.
Sly: "Grandpa, no Principal how you made a decision without my approval and why my future fiance is to be this stranger that you met just to day?."
Sly confront her grandpa with furious eye and walk out slamping the door.
But Kenji standing in the side and ask Principal Val if he can do the request of him, and Principal Val nod that he have hope to him.
After that Kenji thankfully to the Principal and walks out and stop and ask if he can ask for last request.
"Principal Val?, can I ask for the last request? Can we use the training ground so that we can train and polish our skill for future use?."
Principal Val smile and nod and said " Just like old days huh?."
Kenji open the door of principal room cause Lylia was waiting for a minute in the corner of the door when suddenly a running girl bumped Kenji right to his face and Kenji consciousness was a bit blank and he sees the girl panties, when Lylia notice that girl was "Shanne" a gloomy girl with big boobs and Lylia gets jealous because when Kenji try to get up he touches the boobs of Shanne.
Shanne mind was blank out and had no idea what's going on and scream and runs away.
"What happens to her?, I feel I touch some soft part of the wall".
Lylia slap Kenji out of jealousy and said to Kenji that she will go home.
Kenji didn't know what Lylia's problem.
Kenji wonder at the academy because he didn't know where is the training ground and he was notice by the troublesome twin "Jyn & Jannia".
Jyn & Jannia was a troublesome identical twin and when they were born their mother suffer and died when delivery both of the twin.
The twin notice Kenji because he doesn't wear formal uniform that academy rules applied to enter the academy.
The twin got an idea to lure and played with Kenji because Kenji's personality was a handsome boy with great physique.
Kenji notice that he was being watch and run as fast as he can so that he can distract them and he didn't know that he was in dark secret basement side of the academy.
"So this is scary than the horror I watch"
Kenji didn't notice the sign "do not enter academy property" and he ignore it.
Kenji open the secret basement door and he sees so many books that have record on it many years of magic exist.
Kenji notice something shining in the middle and the status window pop out that book was over 500 years old and that book cannot be read by normal person.
Kenji touch the book out if curiosity and the status window pop out again serializing the book.
"Identification Analyzing"
"The Book of the Devil"
"Information: this book have the old record of ancient demon that have powerful ability to conquer all men just by her charm"
"Duration Left to use is 1 week"
