This morning, I was casually browsing /r/lightnovels. Reading some discussions when I fell on that :
While we will mourn the loss of Noboru Yamaguchi, I propose for those who don't know about it yet, to read Daybreak on Hyperion. Akin to Zero no Tsukaima, apart it's not light, and not Japanese. Enjoy this excellent reading with the two first volumes while the author, Aorii is resuming the writing with the third.
