The Ultima Shadow song:

Hentai makes my day, hentai makes my life
Maybe that's the reason, I've never had a wife!
The more of it I get, the more of it I want
Hentai girls can do stuff that, the real girls can't!
Hentai babes got boobs, bigger than yours
Their perfect bodies turns me on, all the time of course!
Hentai girls are cute, hentai girls are hot
But the real girls in this world, sure are not!
Hentai is so awesome, hentai is so good!
Ultima Shadow seems to be, in a horny mood!
