Taira Taizan

Taira Taizan was an Obelisk Blue student who couldn't always get the card he wanted to draw so he went to live out in the jungle to perfect his strange drawing technique since the nature was the only thing that answered his call for help perfecting his drawing technique. That alongside a survival training gave him a wildman-like appearance wearing what's left of his pants. (Source: Yu-Gi-Oh! Wikia)
