Wit Studio must be very busy these days as now they are responsible for not only "Rolling Girls," but also "Seraph of the End." Add in their work for "Attack on Titan" and it seems their animators likely have little extra time on their hands.

But for all their hardwork they may instead have a little extra money.

Recently some new Japanese voice cast members as well as a trailer for the upcoming Wit Studio produced series "Seraph of the End" were released. The series, which is based on the manga created by Takaya Kagami, Yamato Yamamoto, and Daisuke Furuya, is set to premiere this April.

Fans on Crunchyroll have shown positivity and excitement for the upcoming fantasy anime series.

"I'm already excited about this one, but if crunchyroll gets it, I might not be able to control myself from jumping up and down squealing like a little girl..." explained Longdanzi103

"Hope to god crunchyroll gets this," said Gohanjr.

"'Blue Exorcist' meets 'Attack on Titan.' Hype Train," joked SimplyMimiOta

According to Anime News Network, Tomoaki Maeno and Tatsuhisa Suzuki are the most recently announced voice cast members for "Seraph of the End." Maeno is set to play Kureo Hiragi and Suzuki is set to play Shinya Hiragi. Both characters are members of the Japanese Imperial Demon Army but Kureo Hiragi is lower in rank. Both have pretty high ranks however, so perhaps it doesn't matter.

Previously announced cast is as follows: Miyu Irino will voice Yuichiro Hyakuya, Kensho Ono will voice Mikaela Hyakuya, Yuichi Nakamura will voice Guren (Glen) Ichinose, Takahiro Sakurai will voice Felid Bathory, Saori Hayami will voice Shinoa Hiiragi, Nobuhiko Okamoto will voice Yoichi Saotome, Kaito Ishikawa will voice Shiho Kimizuki, and Yuka Iguchi will voice Mitsuba Sangu.

ANN describes the story of "Seraph of the End" as follows:

"The story takes place in a world where an unknown virus has killed the entire human population except for children. Those children were then enslaved by vampires. The manga centers on Yūichirō Hyakuya, a human who dreams of becoming strong enough to kill all vampires."
