Anko Uguisu (CV: Miyuki Sawashiro)

Based on the manga by Kotoyama, Call of the Night is directed by Tetsuya Miyanishi and Tomoyuki Itamura and features animation production at Liden Films. Sentai Filmworks is streaming the series as it airs in Japan on its HIDIVE service, describing it as such:

Wracked by insomnia and wanderlust, Ko Yamori is driven onto the moonlit streets every night in an aimless search for something he can’t seem to name. His nightly ritual is marked by purposeless introspection — until he meets Nazuna, who might just be a vampire! Ko’s new companion could offer him dark gifts and a vampire’s immortality. But there are conditions that must be met before Ko can sink his teeth into vampirism, and he’ll have to discover just how far he’s willing to go to satisfy his desires before he can heed the Call of the Night!
