Reality

Mayumi died with the knife still stuck in her mouth. The knife penetrated to the nape of the neck. Blood was pouring from Mayumi's eyes, nose, ears and mouth.

Beside him, Kyosuke's corpse was face down, his head facing upwards. Rotate 180°. His neck is broken. His tongue stuck out.

Right at Shinsuke's feet, Kensuke's corpse also lay. His body was curled up on the cold floor. His left chest was stabbed with a fork.

Whose deed is this? What kind of monster kills viciously in just few minutes?

"That's how they restrained you, My Tantei. No wonder it was so hard for me to take you with me." A voice from behind Shinsuke.

"Ke-kenkyo? This can't be your doing, can it?"

"Oh come on! I'm so mad at them. They won't let me help you."

"W-wait! You're not Kenkyo! Who are you, Monster? Why did you kill my friends, huh?"

"Tch! Friends you say? Silly!"

Shinsuke gripped Kenkyo's arm.

"WHO ARE YOU REALLY, HUH?"

"I am the one who will help you."

Kenkyo frowned. She looked at her watch. Time is up.

"But, dammit! Looks like I failed again today. Alright, I'll come back later. See you later, My Tantei!"

Shinsuke saw Kenkyo walking away. It gets more and more blurry and eventually disappears.

"WAIT!! DON'T GO!! DON'T LEAVE ME!!"

(KENKYO_POV)

It's only been a few days since I got to see him again. My great detective, Takahashi Shinsuke. I don't know what kind of life he's been through for the past four years. What is clear, I was only able to meet him the day after tomorrow.

Rather than DID, namely: Dissociative Identity Disorder, it is more about schizophrenia. My detective deliberately created his own world. There he can be perfect as he has always wanted. I don't know why, but Okaa-san once told me that it all started when she couldn't save his brother. Even though it was clear that my detective was given time to save his brother, Masaru.

*Okaa-san = mother

Yes, Masaru had been in the real world. However, he was killed by a crazy psychopath when Shinsuke was just a detective. Not only Masaru, many victims fell after that. The killer presents a riddle that Shinsuke must solve. However, Shinsuke is always late in solving puzzles, as a result the psychopath kills the victims.

It all put a mental strain on my detective.

He felt very guilty for the deaths of all the victims.

To this day we don't know where this crazy psychopath is hiding.

Shinsuke had been put in rehab before. However, I didn't expect his illness to recur when he met me.
