The series was directed by Seiji Watanabe working off of series composition by Masahiro Yokotani.
The Re: Zero series worked a “break time” series of shorts over the first half of the main show’s run to have a little fun with the characters as released by Kadokawa.
Plot concept: Natsuki Subaru, an ordinary high school student, encounters a beautiful silver-haired girl from another world.
Subaru wants to stay by her side and help her, but the burden she carries is far beyond anything Subaru imagined.
