The gothic mystery anime The Case Book of Arne has introduced three new voices joining its cast — just two months before the series premieres on January 6, 2026, in Japan.

The latest update introduces:

• Zisye, voiced by Yuki Sakakihara

• Nachzehrer, voiced by Yuki Shin

• Amy, voiced by Yoko Hisaka

These three characters, featured in a new visual, offer deeper insight into the hidden world of vampires, cryptids, and nobles that define the twisted streets of Lügenberg.

The trailer teases even more supernatural suspense and dramatic showdowns as Lynn and Arne step further into the shadows of the city.

The anime is directed by Keisuke Ino at Studio SILVER LINK., with:

• Series Composition: Murasaki & Keisuke Inoue

A TALE OF BLOOD, MOONLIGHT, AND UNLIKELY ALLIES

The series follows Arne Neuntöte, a vampire detective with a reputation for danger, and Lynn Reinweiß, a noble girl obsessed with vampire lore. Their lives become entangled after a grisly murder draws Lynn into Lügenberg, a hidden city where humans and monsters coexist in uneasy silence.

What begins as a chance encounter soon spirals into a spiral of bloodstained mysteries, forbidden magic, and trust tested under crimson moonlight.

"Come on, human. You may dance merrily under the crimson moon.”

With its unique blend of gothic noir, murder mystery, and fantasy intrigue, The Case Book of Arne promises to offer something rare for winter anime watchers in 2026.
