Jiken jaken meaning jiken=cases jaken = from evil point of view Yuriko- Senpai is your typical silent type beautiful high school senior. Like any of those cool beauty silent type, she excells in everything from sports to music from studies to solving mysteries. As a matter of fact only thing that gets this silent Senpai excited is mysteries. She is very passionate about mystery solving. The harder the better. Her partner is her kohai Tori-kun. He loves his Senpai and gets jealous of other men trying to get close to her. Together they solve mysteries around the city often urban legends with occultic, supernatural elements.. I don't knowwhat anyone else think but for me it's my favorite genre.
So even it there are lots of similar mangas like this and characters, i love it.

All mystery fans and occult fans should read this.. lots of comedy as well..

Hoping it gets an anime or a live-action drama sometime in the future.
