Altair

Suddenly she starts getting really bad headaches, ones that make her powers go haywire, levitating objects around her without her control. She even starts to feel the emotions and thoughts from the people around her, sometimes to the point its overwhelming.

Even worse, is that she starts seeing tall grey men watching her in the distance, seemingly appearing and disappearing without a sound or trace after she turns around. She doesn't know who they are, or what they are, but every time she sees them, she is filled with pure terror.

Then one day during a nasty fight with an evil Yokai, she transforms. Her body morphing into an Alien as her powers lash out, sending the monster attacking Okarun into orbit.

-They don't know it yet, but Momo is actually half alien. Her mother went on at trip to America, where she was abducted by grey aliens. Her mother fell in lover with a grey alien and they had a baby, but the two disappeared, leaving behind Momo.

-Momo, as a baby, was then brought back to her grandmother in Japan by a man dressed in a black suit and sunglasses. He told Seiko that this girl was her grandaughter Momo, and that no matter what, she must be protected at all costs.

-As soon as Seiko turned away from the man with Momo bundled in her arms, he was gone.

-With her Alien DNA awakened, Momo experiences a scary side effect if she uses her powers too much, or of she gets overwhelmed by her empathic powers; she will simply stop feeling.

She will become emotionless and her attacks are more ruthless and deadly. Her skin will also turn grey and her eyes will become pitch black as her radiant soul becomes a void.

-She will regain her emotions later the next day, but more often than not, it's Okarun who manages to snap her out of this state, either though soft touches or kind words.
