The Great Snake's Bride Vol. 5 (manga)

Daija and Miyo have overcome the barriers of their interspecies relationship, but the hurdle of becoming interspecies parents is the newest challenge! Their twins are both a different mixture of human and snake. They need to learn the ways of both worlds as they grow. And while no one minds the more human-looking Ina hunting and climbing trees, the more snake-like Tokitarou isn’t very welcome at writing lessons in the village. When other children are so cruel, will Daija and Miyo find a safe, humane way to solve their problems? Or will they need a snake-like solution?
