Hitoshi Kobe is an underachiever, both physically and academically; two of his few talents are computer programming and creating artificial intelligences. His thirtieth creation, known as Saati, is so lifelike that she is capable of holding conversations with him, just like a real person! One evening, Hitoshi jokingly asked Saati, 'If you became real, would you be my girlfriend?' to which she replied yes. But nothing could have prepared him for the freak lightning accident which inadvertently transferred Saati into the real world!
Urashima Keitarou is a loser. He's failed the Tokyo University entrance exams two years in a row, and his parents have finally kicked him out of the house. Penniless and destitute, he travels to his grandmother Hinata's inn, hoping she'll put him up until he can get into Tokyo U and fulfill his promise with his childhood sweetheart (whose face he can't even remember). Unfortunately - or perhaps fortunately - it turns out that the inn is no longer an inn... it's an all-girls dormitory, as he discovers in his typical blundering fashion by grabbing an eyeful and more of every girl in the place! Narusegawa Naru, a fiery-tempered high school student and the first victim of Keitarou's lewd bungling, wastes no time doling out brutal punishment and preparing to kick him back out to the street. But wait! A letter has come from grandma Hinata, and Keitarou is to be the dorm's new live-in manager! Is this a blessing from heaven, or has he been cursed to a living hell?
Both are by Ken Akamatsu, and they share a similar theme of a nerdy guy somehow finding himself surrounded by many beautiful women. The art in A.I. Love You is a bit rougher, being one of Akamatsu's earlier works. Storywise, A.I. Love You is halfway between Love Hina and Ah! My Goddess. But the characters themselves are where Akamatsu shines, and you won't be disappointed.
The two of these have a similar story of a guy hopeless with love and his bout with relationships with pretty girls. Further into the reading, you can spot out the subtleties of gags and such that look to be the precursors of Love Hina. I believe that Akamatsu does a wonderful job with his characters and many of the characters in Love Hina bear resemblance to those in A.I. Love You. The art style is different because A.I. Love You was released earlier, but it's not a big thing to worry about
Keiichi Morisato is a shy student who serves as an errand boy for his roommates. One day he tries to order some food, but accidentally dials the goddess help line instead! A goddess named Belldandy arrives and tells him she will grant him any wish, but only one wish. He doesn't take her seriously, thinking his roommates are playing some kind of prank on him, and decides to play along and call their bluff. Being unpopular with the girls, he wishes to have someone like Belldandy stay with him... forever! Much to his surprise, Keiichi's wish is granted and Belldandy herself will stay with him forever; and that's where the trouble begins. Women aren't allowed in the dorm, and the magical force that granted the wish won't allow them to be separated. As if things couldn't get worse, Belldandy's sisters begin to show up as well!
A similar story structure. A non-popular boy who is lonely and conviently has his house to himself, gets a girlfriend not early. (In A.I. the girls are compter programs, and O.M.G. they are goddess). The romance, and how the relationship between the protaganist and the main girlfriend is really the same. However A.I. does have its own unioque values, ts funny, romantic and an all around good read if this sorta thing catches your eye. If you like one you'll enjoy the other
Youta "Dateless" Moteuchi doesn't have any luck with girls; he has a crush on Moemi Hayakawa, but his chances are less than zero percent. However, once Youta hears that she's interested in his best friend, he finally gives up on her. On his way back he rents an odd sex video tape from the video store Gokuraku. At home, he plays the tape in his broken VCR when suddenly a beautiful girl named Ai Amano pops out of the TV. She's a Video Girl existing only for him, whose purpose is to hook him up with Moemi. Though, because the VCR was broken, so is she: Ai can love him, too!
Both titles center around a love luckless boy and an imaginary girl come to life. In AI Love you the girl is a computer progam created by the male lead, in Video Girl AI she is a video from a magical rental shop. Both are about the trials they go through sorting out their relationships between themselves and others. AI Love You is more comedy centered while Video Girl Ai has more of a drama flavor.
