Maina (マイナ), dubbed mAina, also known as a Baby Chick by the Houtua is a secondary character who was introduced in the 2017 Godzilla film, Godzilla: Planet of the Monsters. She is a shrine maiden for the Houtua, alongside her sister, Miana. Maina bears a striking resemblance to her sister, essentially being identical in design and aesthetic.
Maina is more cautious of humanity, a stark contrast to her more curious sister. She is also more aggressive, with her expressive nature being noted by Haruo Sakaki, who used it to differentiate the duo.
Maina rescued Haruo Sakaki from the wreckage of the destroyed drop ships and treated his injuries, though he initially assumed Miana had been the one who did so. Maina accompanies her sister in spying on Haruo's date with Yuko Tani, expressing irritation; and telepathically helps Haruo evade Godzilla's attacks during the Mechagodzilla City battle alongside Miana. When Haruo rejects Miana's offer to "connect life" with her, Maina later extends the same offer and reveals she was the twin who had saved him. Maina is left pregnant with Haruo's child, and later marries him.
