Squid Girl decides that the Lemon should test their defenses against other invaders. But little do they know Squid Girl has other plans for this mock invasion...

A fight breaks out between Squid Girl and Eiko and this time things aren’t patching up as quickly.  With the tension in the air Chizuru closes the restaurant early so the group can go to the local Festival.  Will Squid Girl go back to the sea or will a mysterious visitor be the key.
You silly. Did you think 
I'd get mad about that?

No seas tonta. ¿De verdad crees

Imbécile.
Sua boba. Você acha mesmo que
 eu ficaria brava com isso?
