Zumina (to the right) is the leader of the force that took over the Kingdom of Black Maw, causing Taiga to flee. Little is known about her, but she had the ability to create "Golems" to do her bidding. Much like her golems, Zumina takes on a bit of rock theming as well.

Sinaga is a special golem; whereas all other golems are made from stone (and whatever other materials are around) and Mass (effectively the "life" of a Yondard), Sinaga is nearly pure mass, is more intellegent, and is almost always ready to protect his master. That said, she is plenty able to defend herself with her hair.

While most would not understand, Zumina is the only one around with a human face. She herself is shrouded in mystery as there are only two Yondards that know her past.

Her reasons for taking over Black Maw are not immediately clear. It can be assumed she simply wants to rule, and is actively searching for the missing prince, but she has no intention of killing him.
