12RIVEN -the Ψcliminal of integral-

May 20th 2012, 11:05. Renmaru Miyabidou receives a mysterious email:
"Today at noon—a lone girl will leave this world."
"Killed—at the top floor of Integral..."
"The girl's name is Myuu... I'm sure you're familiar with that name."
"Remember the promise—the vow—you made that day... Renmaru."

Public Safety police officer Narumi Mishima receives an email from her friend and coworker:
"Soon, a girl is going to have her life stolen from her."
"Narumi-senpai, please. Protect her. Please protect Myuu."
"To stop their plan—the Second Eclipse Project—her existence is a necessity."

The two of them rush to the abandoned Integral hotel building, and what they encounter is beyond belief: a group of people able to use Ψ, a strange special ability.
