Unfortunately the current work in progress for the Tokyo Babylon 2021 anime project has scrapped over multiple accounts of plagiarism.

The issues first arose when Character Design Art was posted online and fans pointed out that costume designs for two characters had been copied from other sources with very little changes. The designs in question were taken from a 2017 Volks Doll and a photo of Yeri from K-pop group Red Velvet then applied to Hokuto and Subaru Sumeragi. However other instances were found by the production team upon investigation, putting the whole project in jeopardy.

The series was supposed to begin in April 2021 but has now been delayed as production work will have to be restarted from scratch to avoid any copyright infringement.
