Seraph of the End is a Japanese dark fantasy manga series written by Takaya Kagami and illustrated by Yamato Yamamoto, with storyboards by Daisuke Furuya. The series is set in a world that allegedly comes to an end at the hands of a "human-made" virus, ravaging the global populace and leaving only children under the age of thirteen untouched. It is at this time that vampires emerge from the recesses of the earth, likely followed by age-old horrors of the dark thought only to be myth. A young man named Yūichirō Hyakuya joins a vampire extermination unit to avenge the deaths of his orphaned family and reclaim his childhood best friend Mikaela Hyakuya from the vampires. It started publishing in Shueisha's Jump SQ in September 2012.

Weekly Shonen Jump was a digital shōnen manga anthology published in North America by Viz Media, and the successor to their monthly print anthology Shonen Jump. It began serialization on January 30, 2012, as Weekly Shonen Jump Alpha, with two free preview issues published in the buildup to its launch. Based on Shueisha's popular Japanese magazine of the same name, Weekly Shonen Jump was an attempt to provide English-speaking readers with easily accessible, affordable, and officially licensed editions of the latest installments of popular Shōnen Jump manga soon after their publication in Japan, as an alternative to popular bootleg scanlation services which were illegal and often poorly translated. It attempts to copy the Japanese magazine.
