The Spirit Detective Refuses to Become a Second Personality

1.

On the night of her birthday, Satsuki Shijiuta suddenly discovered that she had gained a second personality who claimed to be Edogawa Ranpo. Even though Satsuki Shijiuta wasn't a mystery novel fan, she had heard of the famous mystery writer.

She figured that maybe her subconscious wanted to become a famous mystery novelist, so it had created a second personality who called himself Edogawa Ranpo.

But the second personality's dream in life wasn't to become a mystery novelist. It was to become a detective.

The second personality, who wanted to become a detective, said he was a famous detective from another world. He didn't know why he'd ended up beside her or why he could only communicate with her, but first things first: he would become the world's greatest detective and make the name Edogawa Ranpo famous throughout Japan.

Satsuki Shijiuta nodded along out loud, but inwardly she found the whole thing utterly baffling.

Because the name Edogawa Ranpo was already famous throughout Japan!

When Edogawa Ranpo woke up, he discovered that he'd suddenly become the spirit of someone from another world. He was forced to stay within a one-meter radius of her and couldn't leave. He could only touch things she had touched, too.

But this other world was quite interesting. There were no supernatural abilities or transcendents, yet there were writers with the same names as ability users, and a great many cases, each with particularly ingenious methods. It was all very interesting.

Edogawa Ranpo was satisfied with everything else about this other world, except for one thing.

Satsuki Shijiuta was a complete idiot!

She wouldn't believe him when he said he wasn't her second personality! She even got simple math problems wrong! She couldn't figure out cases whose answers were obvious at a glance! She was always easily fooled by the culprit, and she got sad whenever someone died!

How could anyone be this stupid? Her brain was even simpler than that of a barely evolved paramecium! Even crunchy potato chips and fizzy soda were better at solving mysteries than she was!

But! But...

But why couldn't he help wanting to wipe away the tears when he saw them falling from the person in front of him?

Damn it! He must have caught her stupidity!

Anyway, when would he be able to get back into his own body? He couldn't even touch this idiot like this!
