[@Life in Stasis] I believe they were broken by an attack hence the odd shape. 

And yeah the anime isn't everyone's piece of pie. I love it - it's silly, it has nice humoristic plays on the niche's of other animes. For instance the ninja guy is an obvious play on Sasuke from Naruto. Saitama is a play on Goku. And that homosexual man in prison is something something's adventures.

That's why I like it. :p
