Where do humans originate from? After their death, where should they belong?
It was said that, their bodies will return into soil, and their souls will depart to the afterworld.  
However, why do ghosts exist?
Why do they linger in the human world, unable to rest in peace?
So, is death the end of all troubles and sorrows?
When all hopes are gone, is death the only way out?  
I don't know, don't wish to know, and will never know. 

There was a rumor where those who remain in school after midnight will never be found again. Remi and Shinna's stubborn classmates decided to try that out. In two days, five girls have disappeared from the world. Weirdly, the missings' existence seem to be erased, like they are never born into this world. Only the protagonists remember them. Out of curiosity, Remi and Shinna decided to sneak into the school compound around midnight for investigation. What awaits them? It's up to the player to discover...

(　ﾟ∀ﾟ)o彡° Oppai!! (　ﾟ∀ﾟ)o Oppai!!

Remi is an airheaded slutty catgirl. She's 18 years old, is in 3rd year of high school, and has a loli height of just 146cm. I guess she has G cup.

 
Cute, calm and steady.

Shinna is a dandere but wise foxgirl. She has same age and height as Remi, and are in the same class too.  She's not completely flat though.

Since it's about school, of course it happens in a high school. A school with three 10 storey blocks, joined together to form a triangular prism. Sounds bad if trapped inside, right?
