Ecru was born at Ueno Castle and is one of the eight eggs laid by Kaya with her mate Koji. He is a hybrid between cerberus hydras and orthurian hydras. He looks most like his father, Koji, with three heads, two tails and thick, golden brown scales covering his body.
- Ecru is named after the shade of yellow of the same name.
