HAPPYLAND

It started on a nice family trip with my beloved wife and children.
I thought that this happiness would last forever.
That is, until we got lost and stumbled upon this “amuse-END park”.
Hidden pasts are revealed.
Bonds are broken.

Showing the darkness of human nature,
This is a new horror series released by Shingo Honda, author of “Hakaiju” and “Kiriko”.
Presenting the best “family collapse” horror.

The title is a pun on amusement park, so there's no direct translation.
closest English translation that I got is "amuse-END park"
