This might very well be the absolute funniest anime I have ever seen. The plot was intriguing, full of twists and turns. At time the clever planning and schemes reminded me of Death Note.
The art is top notch, with great animation even when you wouldn't expect it. The characters are also incredibly detailed, sometimes even realistically shaded which I have never seen in an anime before.
And to top this all off, boobs.
Watch this if you enjoy laughing and being happy.
Now it's time to go read the manga!
