From Casanova:

After being kidnapped by an "alien woman", Yuuta developed a severe case of gynophobia. Having to be in charge of a bath house, Yuuta couldn't be more inconvienced by this. Just when he was thinking of trying to cure his phobia no matter what, a beautiful girl called Uni suddenly appears in front of him, and that's not all, that girl says she's the daughter of the alien woman who kidnapped and that her mother won an award by investigating him. Her mother feels truly grateful for this so she sent Uni to repay Yuuta with anything he desires and told her not to come back before she does it. What will happen after Yuuta asks her to cure his phobia in the least painful way possible?

Mukai Sachi is extremely unlucky. Stubbed toes, lost items, bird poop... it all happens to her. Her most unfortunate problem, though, is Gokurakuin Misako, the only member of the Occult Research Society. Misako is an honors student, beautiful, very strange, and friendless. She is interested in Sachi's "power" because she wants strange, unexplainable things to happen to herself, too. The problem is that Sachi has absolutely no interest in the occult, so Misako's continued, oddball attempts to get her to join the Occult Research Society are yet another piece of bad luck for Sachi!

In a not too distant future, the world is confronted with a host of issues: pollution, resource depletion, population expansion, and so on. In response, the Japanese government developed sensory simulation capsules (“beds”) and successfully launched a virtual reality program — “Gaia.” Interestingly, the designers omitted the concept of pain from the program, and as a result, there are no such things as pain or death in this new virtual world.

On a day that started as any other, Oono Yuuri stumbles across a mysterious card, which sets off a chain of strange events that evolve into a tale of conflicting dreams, unlikely friendships, and reluctant vengeance.
