If you liked the Alien Nine anime, the Anime-Planet community thinks you'd like:
What happens when authority and consequence are removed? When the inmates truly run the asylum. On the spaceship Ryvius there are those who would fight for order, and many more who would fight to destroy it. Love, hate, anger, greed, avarice, and perhaps hope are the fuel for the Ryvius, and only one can save those who call it home...
If you thought the reactions of the characters in Alien 9 were disturbing, then have a look at Infinite Ryvius. Social experiment where children turn into... oh, well, you'll see (no, they don't grow tails or horns, but their psyche does change)
On a day like any other, average middle-school-student Yurie Hitotsubashi got the surprise of a lifetime – she became a goddess! Unfortunately, even with her newfound powers, Yurie still can’t manage to find the courage to confess to Kenji, her crush. With Yurie’s fame comes others’ fortune; Matsuri, caretaker of the local shrine, names Yurie the shrine’s new goddess and becomes her manager – for yen and glory! Along with Yurie’s faithful best friend Mitsue, the trio set forth on an adventure to find out what it really means to become a goddess.
In both of these main characters are just toxicaly cute, and infinitely weak.I personaly didi not like any of them much, but if you like amines with no story and physicaly weak characters you should like these.
Alien Nine have a bit more violence Kamichu have more cutiness
Amidst a beautiful sunset, Shu is violently whisked away to a grim future devoid of water, and empty of hope; a place where children are forced to become soldiers, and kill countless others in the name of King Hamdo. Shu's companion is a mysterious girl named La La Ru, who may hold the key to survival. Now, he must concentrate on the only things that matter: escaping Hellywood, and finding a way home.
"I have only abandoned my body, I still live here" - are the words emailed to friends of Chisa, several days after her death by suicide. As Lain delves deeper into the world of the "Wired" (also known as the internet), the line between it and reality becomes more and more unclear. Close the world, open the nExt.
Both Lain and Alien Nine are scary, quirky, and off-beat. Both series are also brief but well-executed story-telling gets the point across. (Alien Nine doesn't have a definitive ending.) Both stories center around a timid girl put in bizarre situations, and nobody else seems to notice.
Also, if you really appreciate clever soundtracks then you should watch both of these series. They're total opposites but they're very effective. Lain sounds like electric buzzing, city sounds, and techno; Alien Nine sounds like a magical girl show with happy J-Pop despite the horror on-screen.
