To promote even more diversity in the subforums, let's have another mystery title that I can't believe no one has mentioned it yet!

I'll try and classify all topic according to main genre (would be a bit of challenge since LNs usually mix a lot of genres together)

Anyway, this one ain't a LN but YA novels series, which earned a honorable mention in the Kadokawa School Novel Prize competition

Author: Honobu Yonezawa (A recurring name on Kono Mystery ga sugoi ranking)

Publisher: Kadokawa Shoten

Status: Ongoing

Anime: 2-cour anime by KyoAni (covered 4 volumes)

Manga: Not licensed by a company in NA or the UK but it's available in English from Malaysia's Kadokawa Gempak Starz

Hotaro Oreki, a freshman with one interesting motto "If I don't have to do something, I won't, but if I have to, I'll do it quickly.".

Basically, he's eco-friendly, you gotta save energy, right?

His closest friend, Satoshi Fukube, is quite the opposite.

Living the so-called pink-colored life of a highschooler, participating in any club or activity he find interesting.

A guy like Oreki wouldn't be caught within the distance walking of any club yet he's joining the dying Classics club "Koten-bu" pressured (forced?) by his sister's letter.

Only to find someone who will break his energy-saving life, a very very very (is that enough 'very'?) curious girl, Eru Chitanda.

Our cast won't be completed without the harsh on herself and others, manga-lover, Mayaka Ibara.

The series mysteries are type of everyday mysteries, initiated by Eru's curious attitude and inability of Oreki to refuse acting as her sleuth.

The series doesn't only focuses on mystery aspect but shows interests, in subtle way, in many emotions of the main cast varying from love to inferiority complex.
