Overall, kinda funny but that's really it. If you've seen Kaiji, it's worth checking out, if not, you can still watch it but you should watch kaiji first.
It's bad, no doubt; however, it's like a car crash. You still want to keep watching it even though you know its bad. The yuri is fine but would not recommend unless you like bad stuff.
Woah... This is some gooooood stuff. Okay, so the synopsis sounds kinda lame, but really its not it. This is heaven. Do recommend. Characters are nice, plots pretty nice, and the animation style is on point.
