This is Sougo . While mining at night , he suddenly sees a flash of light across the sky . The beam then shoots straight to where he is . After regaining consciousness , Sougo is surprised to find a beautiful and precious stone in his hand . He then happily runs home . When returning to town ,Suogo speeds at full force but slows down when seeing the police showing good judgement . He then rushes off and nearly collides with a little girl who rushed to the streets . Luckily his driving skills help him to avoid her . He then returns home and informs his uncle Domon that he had returned from mining . He then goes up to his room and examines the stone . Believing that he had found what his mother had longed hoped for . Suddenly he sees some hallucinations . Uncle Domon then calls sougo and asks if he has brought back bread which startles him into rushing out to get it for his uncle .

Meanwhile a government organization has detected unusual energy at the mountain Ravine where sougo went mining that day so they send a captain from the organization to lead the troop thereto investigate . The captain then receives orders and begins to prepare diving equipments for the troops to descend into the deep cave to investigate .

At this time Sougo has gone to buy bread for his uncle and the shop owner asks him to send her greetings to his uncle. He then drives back home when suddenly the stone in his pocket unexpectedly unleashes some kind of power that blows him away and causes him to fall right whaere his friend Kaon is .

She then urges him to get up and climb into the bike telling him to drive quickly. Sougo hears someone calling Kaon but she still urges him to drive faster and even actively starts the engine to drive off with him.

But soon after a young man named Roman chases after them in a car. He asks Kaon why she wouldn't try on the wedding dress and is running away . she says doesnt like this arranged wedding set up by their parents. Roman argues that this is the benefit for the teo families so emotions are not important in this relationship.

She finds Romans words ridiculous and asks suogo if he agrees. Romans younger brother Otto suddenly pops out and asks if Suogo is behind this .kaon then actively turns the engine causing her and suogo to speed ahead. Roman demand kaon return but she refuses to listen. so Roman has to tell otto to force suogo out of the Road

They then crash through a steam cloud and split into two different directions.Kaon and Suogo then plunge straight along a pipe and fall into a huge deep hole

And panics running to hug Suogo and then feels embarrassed and lets go of Suogo. Meanwhile Roman and Otto have also descended into the cave to look for the other two , but also the two are lost . not knowing where they are . Suogo is now trying to fix their vehicle . he thinks that if he can fix the vehicle maybe they can escape because there is the sound of running water , so there must be away out , but Kaon thinks that he’s joking

Suddenly the government organization denenates something in the cave causing the entire the cave to shake . The lake in front of Kaon and Sougo suddenly lights up and the water is completely drained , revealing a pillar with a red glowing crystal inside . He and Kaon then run to the stone pillar . The stone in his pocket is suddenly drawn into his pocket . It then breaks the pillar and escapes . The crystal transforms into a girl and falls gently into Suogo’s arms .He still doesn’t understand what is happening when suddenly the robots of the organization arrive .

They don’t understand why there are “miners “ here but more importantly they see that they are holding what they need to find . So they rush in forcing Suogo and Kaon to run away but both are cornered and surprisingly , the girl Suogo is holding sermons the maker to confront the organization’s robots .

This maker then repeatedly smashes the robots and throws it away . The maker then rushes in for a finishing blow . The captain on the other side sees this situation and realizes that things seem to be interesting . The maker then advances to Suogo when the captain suddenly brings in a robot to confront it . The captain continues to fire towards the maker. Kaon warns Suogo to take the opportunity to leave.

But the maker breaks the captains’ gun and chases after Suogo . The captain then fires the hook and pulls the maker back . He doesn’t understand why the maker cares about the three children instead of him when his superiors then ask him why his target is moving . He checks the rate of the RI and discovers that the real target is the girl that Suogo is carrying . The maker has broken the captains’ steel wire and escaped but he rushes to attack and pulls away . The maker crushes into a pillar causing the dust and smoke to rise everywhere . It then takes the advantage of this chaos to grab the captains leg and crash the hammer so he cant move . But the cave suddenly collapses causing Suogo and Kaon to fall even deeper . Suogo then tries to reach for Kaon and the girl and suddenly the maker flies down to catch them , all three and helps them to land safely . Suogo then meets Roman and Otoo again .

But the uncle tells them to sit down so that he can make something for them to eat .Suogo then tells Roman about this mysterious girl , But the story of a girl falling out of a crystal sounds very hard to believe . However this girl is involved with the military , so they should be careful . And if they want to turn her in , they need to think carefully .Uncle Doman then brings food for them to forget their troubles . Suddenly , the girl wakes up and pulls the plate of cake a little closer to her using her powers . Kaon asks the girl if she likes to eat and offers her a piece . The girl then becomes closer to Kaon and begins to imitate her actions and words . Roman asks if there is anyway to find more information about the girl , but to investigate they at least need to know the name of the girl. Perhaps they should wait the girl to tell them everything so that they can have more information . For now, Kaon suggests letting the girl stay at Suogo’s place . But Roman doesn’t accept this , so Kaon proposes that she will stay here and postpone the wedding with Roman . Romon will persuade his parents and uncle Domon has no problem with this .

At this time , Suogo was about to examine the strange sphere. But as soon as he began to cut it out , the strange sphere cried out in pain then burst open , then turned into a snake and claimed that it would protect the girl that Suogo’s group had kidnapped . It then says that the girls name is Felia . It intends to transform so as to attack suogo but due to lack of enough it fails . Felia and Kaon then run in because Felia refused to dry her hair . She ran away causing Kaon to chase after her . Felia then throws a towel to Suogo allowing him only to dry her hair . The stone snake doesn’t allow Suogo touching Feila’s hair .

Meanwhile the captain has gone to prison to meet a prisoner . As soon as the guards pulls up the prisioners head , he spits a tooth in the guards eyes and escapes from the chair. He clings onto the celling then lunges to the soldiers ..
