 Chelsea is Ruri's bodyguard/tutor, and accompanies her when escaping from the Underground. Chelsea controls powers related to gravity and has a personality to match. She is very dedicated to her task of protecting Ruri, and would gladly lay down her life – in fact she spends much of the early episodes bashing Rumina on the head for being too familiar with Ruri. Chelsea's gravity-power is very strong, and she is a tough opponent. She always argues with Rumina and always gets into a fight with each other, however she later respects him and also develops feelings for him.

Characters.
The Company.
The contains thousands of elemental users, and most are hostile. They wish to bring complete destruction to those who dwell on the surface. Their hatred for the surface world stems from the belief that they were abandoned by them, which really isn't true since only the scientists actually knew of their existence underground. They are also the people who want to awaken the dragons (called "ron") to complete their revenge and are willing to sacrifice Ruri to accomplish their goal. Chelsea and Shiel both turn against the company in order to get Ruri (Maiden of Life) to safety and away from the company.

It is later revealed that Kashin's sister was actually the original Maiden of Life, and Ruri was cloned from her when the attempt to use her to revive the Ron failed.

The highest-ranked soldier of the Company. A reckless Water-user who loves a challenge. Went with Pairon to capture Ruri at Rumina's school. After being defeated by Rumina, he was determined for a rematch, which he did at the Underground Hole. When Rumina tried to save him, Tailor told him about the Underground's bitterness toward the surface, especially when his poor parents sold him to the scientists. He removed Rumina's grip and fell down the Underground Hole, claiming he will not die and will cross paths with Rumina again. Also, referred to by Rumina as "pony-tail".

The Ron.
Like the elemental power user humans, the Ron were created by the same scientists. According to Chelsea, they physically resemble dragons of mythology but are merely artificial forms of life. The Ron lie dormant, but the Company intends to use Ruri's power of life to revive them and set them upon the surface world to punish those who had wronged them so many years ago.
