Asagi Ryuugasaki

Asagi is portrayed as a loving and caring person.

Asagi was the mother Hiro Ryūgasaki and close friends of Leon Aurenche. Along with her husband Eiji Ryūgasaki, they worked along Leon in Genesis Corporation researching the Tree of Woe, which eventually lead to Asagi being possessed by Nexus. As the Tree of Woe spirals out of control, Asagi ended up sucked into it and Eiji sacrificed himself to ensure that the Tree of Woe is contained and entrusted Leon to stop its eventual revival, not knowing that it was Leon who actually planned it all to happen. Since that incident, Asagi and Eiji's son had been living with his paternal grandfather.

While trapped inside the Tree of Woe under Nexus's power, Asagi's heart manifest itself in the form of a little girl in order to wake up the seven chosen ones from the Tree of Woe's dream and guides them to save the world. However, both Asagi and Nexus end up being absorbed by Leon in order for him to obtain the power of the Keeper.

When the Tree of Woe tower disappears, Leon falls into the void and awakens to be greeted by Eiji and Asagi. The three then set off for an unknown destination.

Three years later, during Shadowverse Flame, Eiji and Asagi reappears in middle of the Arc Ruler's invasion of Nekome City to save Hiro and Luca from the Shades. Asagi restores the exhausted Nexa System so the two can continue fighting.

Following the defeat of Wolfram Zerga and the disappearance of the Tree of Woe, Eiji and Asagi leave for America with Leon to continue their research to change the world.
