You know, I have a rule in watching anime. It's called a "no drop" rule, wherein I won't drop any anime that I started to watch.

I watched Pupa, and bulldozed through it.
Watched Mars of Destruction, just laughed.
Skelter Heaven? Laughed once again.

I, however, was close to my breaking point here. I almost broke the rule in the frustration of watching anime. But I'm no pussy, oh no I'm not. I tread the most dangerous journey I have faced so far.

Abunai Sisters.

I can't even believe this anime exists. There is no SINGLE redeeming quality read more

The greatest anime of the 21st century.

STORY: The Abunai Sisters, Koko and Mia go on a great adventure, which I have only seen 2/10 episodes of because the other 8 have been lost in the space time continuum. However in the 2 view able episodes Koko and Mia go to locations beyond imagination, such as a beach and a car. Koko and Mia are 2 boobylicious women who hold the booby gem, which makes people want to attack them. The 2 villains (a pervert and an old lady) try to steal the booby gem on this epic quest.

Two sisters, Koko and Mika, hold the Boobie Gem, which is the only reason they're celebrities (and overly-fanserviced), because they're holding the gem, they're gonna get attacked, a lot. 2/10

The "COMBAT", is like: "A sister shakes a bottle like she's giving a handie, and then the cap blinds the robot shark, and she fires a gun and EXPLOSION" This... actually happened. 1/10

The "CHARACTERS", everyone except the sisters, ARE COMPLETELY UGLY, what kind of person thought it would be okay for a pathetic pervert and old lady for villains? Now at the sisters, they are overly-fanserviced, even though they are the most beautiful FOR THIS read more

First Reaction Review: For those that know me, you would know that Ecchi shows like this are not always bad. I like ecchi stuff sometimes, like Panty and Stocking with Garderbelt. This show on the other hand… this show… It’s a lot like Hentai but without the sex. Let me explain, the first episode shows the abunai alarm in the girls breasts (I guess they had surgery to get those done), the way that they fight the shark is shaking the bottle of Champagne up and down while making rather sexual sounds and then popping off the top. There is a lot of sexual references read more
