Haruka Kaminogi
Haruka has a deep, almost supernatural bond with the Yuus from both Earth and La’cryma. Both of them can apparently hear her when she is in distress, even when she is in another timespace. Yuu is initially angry that Haruka is so fond of the blunt, tormented Karasu, unaware that this is because both of them are her beloved Yuu, and that she loves them in the same way.
When Shangri-la attacked, Haruka was almost drowned to harness her powers, but she was rescued by an exhausted Karasu, who returned her to earth. With his help, she continued to evade the remaining Dragon Knights, but later willingly went with Noein if he spared Yuu and Karasu.
Haruka was horrified to find that Noein is yet another version of Yuu, who still loves and longs for her in a very warped, insane manner. Along with Yuu, she denies that Noein is the same as Yuu or Karasu, and destroys his power. She and Yuu return to Earth together, after Karasu promises her that she’ll see him again – in fifteen years, when Yuu is grown.
Some months later, we see that Haruka is anticipating Yuu’s return on vacation, and that she regularly emails him. But she glances over at the church steeple, remembering Karasu.
