I'm the top student in Conan, but I'm actually an onmyoji.

Story of: I'm the top student in Conan, but I'm actually an onmyoji.

Sagawa Yan is the top academic master in the Conan world and is known as a national treasure.

No one knows that he is actually a time traveler, carrying the most powerful academic system.

But he has also had troubles recently, and a second system has awakened in his body - the Great Onmyoji System.

Should I believe in science and be the father of all mankind or should I believe in theology and become the god who controls reincarnation? This is a question.

...

After thinking for a long time, he decided that he wanted them all!

CONAN: This is impossible murder!Is there really a ghost?

Sagawa Yan looked at the shikigami flying in the sky and smiled without saying a word.

Kidd: What kind of magic is this? How could you hide it from me?

Sagawa Yan: This is science, you scumbag
