A tsunami is coming for the cliff made of tofu, but there is a special sect that protects tofu cliff.
All of the members of the sect are standing on the cliff, their hands raised, and right as the tsunami is about to collide with them, they shout, "Ha (は)!" and it's repelled! The tsunami sinks and rolls back out to sea, the tofu cliff is safe!
