Nurse: Wha, what the fuck is happening right now, Doc come here NOW and FAST, we have and emergency.

Nurse: (exhausted) I I need to work out more huh, and a sea of crowd await her. Ok here we go. Coming true coming true Ajuka- sama, Ajuka-sama.

We could see Ajuka sitting in his chair and playing with one of his new toys. He was messy grean hair and wearing a white lab cote with a piece of paper in his hands and a pen in the other.
Ajuka: Yes how can I help you.
Nurse: Hy- Hy Issei Hyoudou vitals are increasing at a fast pace and I didn't know what to do.
Ajuka ( dropping down his new invention): Nurse Hoy I know you think you're joke's are funny but this time you cross the line.
Nurse Huy(scared): No no I would never joke on such topics but his vitals had becoming more active a few moment's ago, and Doctor Doc sent me to get you there.

I'm the same time down stairs we could see Doc analysing Issei heart beats, blood pressure, temperature but at that moment the heat in the room starts increasing tremendously.
Doctor Doc: Fuck Fuck were is he when you need him the most.

Ajuka: Fine I would come but if you disturbed me again you may become- huh that heat were did it come from.... Wait a moment I know just one person who is capable and his...... ISSEI,and bursts thru the door.
Nurse Huy: I I thought he's going to kill me or worst because one of his next test subjects, just the thought of that future sent a chilling sensation on her spine.
