Pluster World (冒険遊記プラスターワールド, Bōken Yūki Purasutā Wārudo, lit.
"Journey of Adventure: Pluster World") is a Japanese anime television series that originally aired on TV Tokyo from April 2003 to March 2004.
According to legend, the peaceful Pluster World fell into chaos with the appearance of the Minusters, and in response, all of the Plusters fought alongside the humans, or, more specifically, merging with them in order to become more powerful ("plusting"), and were able to seal away the evil Minusters.
Completely overmatched in battle, Beetma accidentally finds himself sent to the world of humans, where he meets an 11-year-old boy named Tohma Kaname, hoping for revenge on the Minus-Beast.
Wyburst, looking for the legendary Gonggorahgong, eventually joins them on their quest to defeat the Minusters as they meet many other Plusters and journey onward.
