[Synopsis]

One day, walking around in the woods nearby the anchorage, Cerberus finds a strange looking collar and leash.
It seems to have a gimmick of some sort, so she decides to bring it back to the ship.
''Commander, let’s go take a walk together!''
Whether or not finding the collar made her come to this conclusion, she asks the Commander out on a walk.
The Commander senses something suspicious but ends up deciding to go with her.
Little did he know that this light decision would bring onto him a “heavy” experience...
