Let the dog in and you trigger ED5, the bad ending literally named “Dog.” This is a real route in the free Japanese browser horror game 家族以外は入れないでください, released October 24, 2026. The creator's hint is brutal: even if it's cute, it isn't family. Rejecting an ominous stranger? Easy. Rejecting a dog? That's a different kind of horror.
Full spoilers for all five endings follow.
How the two doors work
You are a child home alone in an apartment. The entrance intercom rings; you choose whether the visitor may come upstairs. If someone reaches the apartment door, you choose again whether to unlock it. Building access and home access are different decisions. Visitors include a delivery worker, strangers, a dog and people claiming to be your father. The official site describes horror without jump scares.
Five endings and their conditions
- ED1 “おかえり” (true ending): Reject the impostor and empty-handed Dad, then open to the real father holding a cake box.
- ED2 “留守番” (normal): Let nobody inside. A cake is left outside in the morning.
- ED3 “だめだ” (bad): Unlock the door for the impostor or the empty-handed father.
- ED4 “ノック” (bad): Admit a visitor who isn't family.
- ED5 “犬” (bad): Let the dog into the home.
Five steps to the true ending
- Refuse the delivery worker, unidentified visitors and dog.
- Read the four written replies from someone claiming to be Dad. The first Japanese characters of the impostor's answers spell あ・け・る・な (akeru na), “don't open.”
- The real father knows it's the child's birthday and says he bought a cake. The order of the two fathers may change.
- Even after allowing the real father into the building, do not unlock the door for the first, empty-handed Dad.
- After knocking and footsteps, the father carrying a cake box arrives. Open for him to reach ED1.
The dog is the funniest trap
An impostor father fits classic horror. A dog turns the rule into a debate: aren't pets family? A kind choice isn't necessarily the correct choice in a game. ED2 is safe but a little sad, ED3 is the price of missing a warning, ED4 comes from trusting a non-family visitor, and ED5 comes from one very understandable weakness: a cute dog. Walkthroughs differ in how precisely they describe ED4's two-door trigger, so stick to the core rule of refusing outsiders.
Bottom line
There are five endings. The true ending hinges on the hidden warning, the birthday clue and the box in Dad's hands. The dog is innocent; the apartment's entry policy simply has no exception for cuteness.
