Machina is Akira's dragon partner, who acts like a big sister towards Akira, correcting her speech and keeping her in check. She states that she follows Akira because she wants to, not because Akira is her master.

Machina is a water type dragon. She has the ability to manipulate water when in her Communicator form. In her dragon form, she can attack with liquid whips and also with concentrated balls of water, along with unleashing countless ice crystals from her wings. These attacks seem particularly effective against fire-type elements.
