The manga series ran in Weekly Shonen Jump from 1998 to 2002 and had a thirty-nine episode anime adaptation arrive in 2002, which was never licensed or streamed.
The project will be using the animation as seen before for the run but with a new dub cast.
Marvelous Entertainment has announced that they’re going to be doing a “voice remake” of the 2002 anime series Whistle! as part of the 15th anniversary of it.
