In the future, Japan faces a massive overpopulation crisis. Scientists have traced this issue back to one individual, Junta Momonari, who was known as a "Mega-Playboy" and fathered children with over a hundred women. Each of his sons inherited the same "Mega-Playboy" gene, causing the problem to grow exponentially.
Meet Karin Aoi, a "DNA Operator." She is sent back in time with a mission: to alter Junta's DNA and stop him from becoming the Mega-Playboy, thus preventing the overpopulation crisis. This can only be done by shooting Junta with a special bullet called DCM, which contains a chemical that suppresses the Mega-Playboy DNA. In return, Karin will receive a vast sum of money—enough to make all her dreams come true. Will Junta become the playboy he is destined to be, or will his better self prevail? However, Karin finds herself falling for the real Junta, complicating her mission. Meanwhile, there’s also Ami, who has secretly loved Junta her whole life. What will happen to future Japan?
DNA²: Dokoka de Nakushita Aitsu no Aitsu was published in Brazilian Portuguese by Editora JBC from July 2009 to November 2009.








Okay, just to get another perspective on this manga.
I read the first few chapters years ago and was amazed!
Now I had the chance to finish reading this manga, and I think all those years of waiting in suspense for a great manga were a waste of time.
The art was fantastic; the sensei is known for his excellent art.
However, the story and characters weren't good, in my opinion.
I got the impression that the author took all his favorite moments from Dragon Ball and put them into a sci-fi environment, with some ecchi added.
It was complete nonsense. Even though the emotions and values shown were decent, overall, I didn't enjoy reading it at all.
This manga might seem uninteresting at first glance, but believe me, after reading the first volume, you'll want to buy the other four as well.
The story appears quite simple initially: a girl from the future trying to make things better. Sounds boring? It would be if that were the only element. In the first few chapters, you encounter what can only be described as pure romance. But as you continue, you start thinking, "Hmm... something else is going to happen." Suddenly, the action kicks in. Unexpected? Yes, especially on your first read. After that, the story develops nicely with smooth transitions between action, humor, romance, and back to action. The narrative doesn't feel forced except for the ending, which, despite being a nice twist, felt somewhat unprepared. Overall, it's very interesting, and even though the fights have a Dragon Ball-esque vibe, it's easy to overlook.
The artwork is clean and shows much love for detail. Even elements usually drawn roughly are given careful attention, giving the surroundings a nice feeling. I'm genuinely impressed by the art overall.
There's character development, flaws, and changes. What more could you ask for? The characters that form the main part of the story are well-developed, realistic, and relatable.
I thoroughly enjoyed this manga and can only recommend that if you haven't read it yet, you should do so now.
