Dangerous
There is a prison on a cliff surrounded by snakes. Now that's a dangerous place. If you try to escape the prison you either fall to your death off the cliff or get bitten/squeezed to death by the snakes. Can you think of anything more dangerous than this? I can't.
Imagine a dangerous prison surrounded by cliffs and snakes. You wouldn't want to be here either, would you?

あぶ, あや
None
Lucky for you, even though you're stuck in this dangerous place, there is hope. There is a key (き). All dangerous prisons have a key. You just have to find and steal it so you can avoid the cliffs and snakes!
Imagine staring at the key dangling right outside of the dangerous prison you're trapped in. Would you take the chance and go for it?
