What is it? What? You can't go past Memory Lane 5? That doesn't sound right... There's nothing wrong with the permission. Hm... Then... the problem must be with you. What kind of problem?

The Whale of Time, Dodo, lives in Memory Lane and eats memories for sustenance. A part of your memory must have been eaten by Dodo while you were fighting it. Because of your lost memory, you can't pass through Memory Lane.

You won't be able to pass through Memory Lane until you find your lost memory. But you already destroyed Dodo, who ate your memory... You have no choice but to seek help from Memory Keeper. Memory Keeper... He is the one who sees all memories with the purity of his heart. He'll probably know what to do about your lost memory.

If you don't think it's a big deal, then that's fine. You just can't go beyond Memory Lane. Does that work for you?

...You are... empty. There is a hole in your heart that used to be filled with a memory. Now it's just empty.
