Now a look back to the first full manga from Ken Akamatsu who is now the most significant figure in the medium right now.

Hitoshi isn't really good at anything except for computer programming, his latest A.I, Saati is a sweet girl who would make for the best girlfriend for him, he ends up getting more than he bargained for when Saati comes to life during a thunderstorm, this begins a whirlwind romance as Saati's unique programming brings new life to Hitoshi's dull existence.
More A.I appear with prototype Toeni and duel gendered Forty, with all the chaos going on from rival love interests, genius hackers and malevolent computer viruses, Hitoshi has more than he bargained for.
This never made it to anime but from what we get it's very much reminiscent of the Love Hina Akamatsu rather than the Negima Akamatsu while borrowing heavily from Ah My Goddess and Video Girl Ai, which argubly means it's been done better but for what it's worth, it's a fairly decent read.
As to why Ken Akamatsu is currently the most significant person in the medium, last week he was voted into the Japanese government's House of Councillors, his main goal is to sort out the copyright and censorship laws as to not penalise creative freedom with blanket bans on certain things, this is a big deal as Anime and Manga deals with an identity crisis as of late as it contends with a global audience that in this era includes people who aren't fully educated on the subject (a.k.a Twitter) so interesting times ahead.
Final Verdict: It has been done better by other series but is pretty solid for a sci fi romance.
