Chapter one - The horrible news

In the morning, Hiroki finished his breakfast with Nowaki. He picked up his briefcase and ready to go. Suddenly, Nowaki hugged him.

"Hiro-san, don't forget our date tonight for anniversary." said Nowaki.

"Of course I won't forget, idiot. Just be careful at your work, Okay?" Hiroki looked at Nowaki.

"Okay. I love you, Hiro-san." Nowaki smiled. They kissed passionately.

Hiroki went to his work as associate professor at Mitsuhashi University and Nowaki helped his patients as a doctor-in-residency at the hospital. While they're at work, a mysterious man in black trench coat, brown fedora and black scarf covered his appearance. He was standing at the top of the building. The blue haired girl with violet, red and pink highlights in rocker clothes went closer to the man.

"So, why are we here?" she asked.

"My former student called himself 'The Demon Massacre' was targeted by the assassination group called 'Deadly Sin'." the man replied.

"I see... You told me that 'The Demon Massacre' is a dangerous man but he quitted to become an assassin. He was happy in his normal life with his lover. I guess the Deadly sin got jealous." the blue haired girl smirked.

Suddenly, the hospital exploded by unknown bomb. The man and the blue haired girl noticed it.

"I should start my mission right away." the blue haired girl ran off.

After a few minutes later, Hiroki finished his paperwork and Miyagi came in with a joyful smile.

"Kamijou, my sweet honey~ are you going home?" Miyagi asked and teased Hiroki playfully.

"Oi! Don't call me that and yes, I have a date with Nowaki at night. It's our ninth anniversary." Hiroki replied.

"Oh, Happy Anniversary!" Miyagi greeted with a smile.

"Thanks, I'm going home soon. I need to pack some grading papers." said Hiroki. He packed some grading papers and put it inside his briefcase.

"Where are you and your lover going?" Miyagi asked.

"I don't know. I told him that I don't like expensive restaurants. Maybe at the sushi bar." Hiroki wondered.

"Try Masatoshi sushi bar. Shinobu and I went there before. The sushi is great." Miyagi gave him an advice.

Shinobu rushed to the office and opened the door in a hurry. Hiroki and Miyagi saw him.

"Whoa! Whoa! Shinobu-chin, I didn't do anything." Miyagi waved his hands for defense.

"Miyagi, the hospital exploded few minutes ago. Dr. Kusama works there, right?!" Shinobu asked.

Hiroki shocked by hearing the news. He didn't know if it's true or not. He suddenly ran off. Miyagi and Shinobu saw him.

"Wait! Kamijou!" Miyagi shouted.

Hiroki ran as fast as he can be. 'No! This is not going to happen! He will be fine!' he was thinking of his mind. He reached to the hospital. His eyes widened open. The hospital burned and the ambulances came. There were many injured people and the workers helped them. Hiroki was just standing and stared at them. Miyagi and Shinobu were arrived and saw the tragedy.

"What happened?!" Miyagi asked.

"I came home from college. Suddenly, I heard a large explosion at this hospital. They saw someone put a bomb in it." Shinobu explained.

"You should call Nowaki, Kamijou." Miyagi suggested.

"Right!" Hiroki pulled out his cellphone and called Nowaki. Nowaki's cellphone is ringing and answered by someone.

"Moshi-moshi! This is the nurse." said the nurse.

Hiroki begun more worried and he knows that someone is calling. "Um...Hello! Can I speak to Nowaki Kusama?" he asked.

"Nowaki Kusama... Sir, he's at Yamiko Memorial Hospital. He's...also got injured by the explosion." the nurse answered.

Hiroki was frightened. He dropped his cellphone by the nurse's horrible news.
