Niracha Neko (ニラ茶猫) is a mysterious derivative of Giko that grows chives on his head. He offers people chive tea, and ends sentences with "Folha!" (ﾌｫﾙｧ!) instead of Giko's "Gorya!" (ｺﾞﾙｧ!).

Derivative:

Niracha Duma

Niracha Duma (ニラ茶妻) is Niracha Neko's wife. Her appearance seems to be based off of Shii. There's not really that much to say about her.

Together, they have a child named Nirachi.
