Manga creator Jun Mochizuki has posted on Twitter that her The Case Study of Vanitas (Vanitas no Carte) manga is going on an indefinite hiatus due to concerns over the COVID-19 coronavirus illness. Mochizuki explained that the process for creating the manga is completely analog, and her assistants would commute to and from Tokyo to work on the manga every month with Mochizuki. However, after consulting with staff at Square Enix, Mochizuki decided it was dangerous to have her assistants continue this commute, and so they decided to put the manga on hiatus for now.
Mochizuki launched The Case Study of Vanitas in Square Enix’s Gangan Joker magazine in December 2015. Yen Press has been publishing the manga simultaneously in English since its debut.
