In one episode of the English dub, Gawl accidentally ends up on a stage while a kiddie show (a parody of the Power Rangers) is going on. One of the girls watching the show exclaims "Oh my God, is he not wearing any underwear?!" as the camera focuses on Gawl's lower body. I'm not sure if the same gag is in the subbed version, but this is enough to make some viewers uncomfortable.
In a particular episode, the main characters are depicted in a spa setting. While one unnamed character's backside is briefly shown, Gawl and Ryo are seated in the water up to their rib areas, with Koji sitting at the edge with a towel in his lap. Masami and Natsume are also present, with no depiction of their chests. During this scene, Gawl stands up to pull Ryo out of the pool, revealing his lower body without explicit detail. This scene as a whole may make some viewers uncomfortable.
Masami mistakes Gawl for a stalker going around Oh-ju in the first episode, and calls him a pervert for a couple later scenes.
There are many sexual jokes in the English dub, with one instance where Gawl refers to Masami as "Short Busts". Another is in a junkyard where Gawl confronts a Generator and says, "Hey, you! Flasher! What'cha got under that coat? Never mind! I'll bet it ain't very big."
