Rinjin -Neighbor-

Sometimes, in life, there are places where the rules of reality just don't apply.

Sometimes it's the one place where you ought to feel safe.

Like your house.

Freelance designer Yuuki Kae has just moved into a new apartment. On her move-in day, she decides to introduce herself to her new next-door neighbor... but something isn't quite right.

A violently rattling doorknob...
And a ghostly pale hand reaching out through the crack in the door...

Through a series of strange events, Kae meets Hisamatsu Daigo, a fellow tenant who lives above her on the 3rd floor. Together, they must hunt for clues to solve the mystery...
