Today I recommend: Black Butler Vol. 1 by Yana Toboso.
Just a stone’s throw from London lies the manor house of the illustrious Phantomhive earldom and its master, one Ciel Phantomhive. Earl Phantomhive is a giant in the world of commerce, Queen Victoria’s faithful servant…and a slip of a twelve-year-old boy. Fortunately, his loyal butler, Sebastian, is ever at his side, ready to carry out the young master’s wishes. And whether Sebastian is called to save a dinner party gone awry or probe the dark secrets of London’s underbelly, there apparently is nothing Sebastian cannot do. In fact, one might even say Sebastian is too good to be true…or at least, too good to be human…
This manga has a nice balance of humor and dark mystery. The fumbling group of servants who frustrate competent butler Sebastian provide the majority of the humor, while the odd interactions between Ciel and Sebastian begin to build the drama and mystery. The ending of this volume is a cliffhanger that will certainly grab your attention. I recommend this for anyone who wants a little bit of a mystery in their manga and for anyone who enjoyed D. Gray Man.
You can find this manga series in the Young Adult Manga section at YA MANGA TOBOSO.
