Milo and Bisco head toward Touhoku in search of the legendary mushroom, Rust-Eater. After reuniting with their friend, the giant crab Actagawa, Milo struggles with his training to ride the crab, but ends up communicating with it thanks to his kindness. That night the two of them try to rest at the Nikkou War Memorial only to reunite with a jellyfish girl they met in Imihama.
No matter how strong you are,
 the two of us can't...
...مهما كنتَ قويّاً، نحن الاثنان لا يمكننا
Egal, wie stark du bist,
alleine schaffen wir das nie.
Per quanto tu possa essere forte,
in due non riusciremo...
Mesmo que você seja forte, 
só nós dois sozinhos...
