Sarutobi Ecchan (さるとびエッちゃん) known in some countries as Hela Supergirl, is a Japanese manga series by Shotaro Ishinomori.

Ecchan is also capable of all sorts of extraordinary feats: she can communicate with animals, possesses hypnotic and telepathic abilities, and is stronger and more intelligent than normal girls of her age.

But with the help of her friends Miko, Taihei and her dog Buku, everything always turns out right.

Since it was cancelled due to low ratings, the series was unsuccessful to continue its run, and there is not a proper ending for Ecchan.

The last episode focuses around an American Ecchan doppelganger named Eiko, who wants nothing more than to see Mount Fuji.
