Angered by mankind's pollution of her beloved ocean, Squid Girl rises from the dark and mysterious depths in order to punish the loathsome human race! Unfortunately, that plan immediately hits more snags than a dozen fishing lines in a washing machine. Not only does her small stature not intimidate humans, but instead of unleashing a tsunami of destruction, her attempts only cause minor damage to a pleasant little beachside restaurant. And then, the unexpectedly aggressive Aizawa sisters, who run the Lemon Beach House, force her to work there to pay it off! They even make her provide her own squid ink for a tasty squid ink spaghetti! Thus begins our tale of a poor not-quite fish out of water: SQUID GIRL!
