Quite a so so anime.
The plot is relativly alright, sort of Highlander meets Tenchi.
The way it is carried out thouh...just awful.
Sure. Otaku like scantily clad girls with big tits but they go really over the top with the booby sizes here so that it just looks silly.
And the art style in general is pretty crappy and cheap looking too.
Oh, and the main villain just looks simply rubbish. Terrible. They've tried to go for a nerd who thinks himself cool look I think there but have just got...something awful as the end result.
On the positive though it does have its funny moments with the Tenchi like 'hes mine hes mine'. Something to watch if theres nothing else. It is only 12 episodes afterall.
