The manga series got its North American release from TOKYOPOP years ago and the first half of the anime series received a DVD release from FUNimation.
The series is being produced as two SDBD collections with the Elementary School arc release set for fall 2021 while the Middle School arc will arrive later in 2022.
The first set will have the bilingual episodes that were produced by Funimation while the second set, which was never dubbed, will be subtitled-only.
