he mangaka behind this one is Masakazu Katsura. You may or may not have heard of him, as he is well known in certain circles and not known in others. His other works include Shadow Lady, Video Girl Ai, and Is.
His strong point seemingly lies in his artwork, which is a constant and it is always good, particularly if you're a guy, since he seems to focus on the more ecchi style of drawing.
Another thing is that your best time to read his manga would probably be while you're in high school, once you're past that age you might not find his manga all that appealing. What this means is that he tends to focus on the emotions and thoughts of high school kids, recurring themes in his works are one sided loves, misunderstandings, love triangles, extreme shyness, uncertainty and anxiety, and a good dose of angst every now and then.
DNA² also had an anime, but as usual the manga is much better.
The manga itself seems to come to a conclusion a bit abruptly as Katsura still wanted to continue it, but was forced to cut it short, the same luck that befell Shadow Lady.
You could say this is because Katsura is a shonen writer trapped in the body of a shoujo artist. What this means is that he often guides his manga in the direction of a fighting series like Dragon Ball Z, but his audience and publishers demands force him to stay focused on the emotional conundrums that seem to be his fort, rather than the more action packed stories he would like. This is proven in Both DNA² and Shadow Lady as he tried to guide both series in the direction of a fighting manga and thus had to cut both short.
Our example at hand, DNA² deals with a high school student Junta Momonari who suffers from an odd, way too odd if you ask me allergy that causes him to vomit whenever he gets too aroused or too close to a woman.
However as a parent might say to a kid with acne this is only temporary as within his DNA lies that of the mega playboy who will father over a 100 hundred children in the future each also fathering over a hundred children as well and so on causing a devastating demographic explosion.
The people in the future are obviously not too fond of this and so they send a DNA operator back in time. What these operators do is shooting people with these DCM bullets that can alter their DNA and so they plan on ending the threat of the mega playboy this way.
Unfortunately for Karin, the operator chosen for this project the bullets get switched and instead of preventing him from becoming the mega playboy it speeds the change causing Junta to constantly shift between normal 'woman allergic Junta' to 'mega playboy Junta' causing all kinds of troubles for both Junta, Karin and the people around them.
Thats the premise of the series, which, as you can see is contrived, but lets go with suspension of disbelief for this one after all its fiction so we cant expect it to be flawless. Past this we can see that the plot being that of a boy who can seduce any woman he wants is just filled with opportunities for gratuitous sexual situations although not as overused as you might think its definitely fairly present through the story as are the constant misunderstandings and the elements that seem to colour every one of this mangakas works.
Now a very big difference between the anime and the manga is that in the manga much more attention is paid to the fact that Junta develops psychic powers as well as amazing fighting abilities when he turns into the mega playboy and he has to use them more than once. In the anime this is nearly completely ignored. The manga also has more depth than the anime does and allows you to care more for the characters.
If you're starting in the manga world and you're in high school you might enjoy this one, but if you're more mature and if youve been in the manga scene for a while, then you probably wont find this one all that appealing.
