Kirihai and mirio were walking inside an ancient ruin which seemed to be a city that was abandoned over hundreds of years, Kirihai explains to mirio that ukina said that the millennia stone that holds the divine beast of the sand is around here. Mirio who was using his chains to float above Kirihai sighs and says that they should finish this and get it over with already. Kirihai then tells him to stop whining and that they both should do their best. Kirihai then see's a stone with a bright brown light on a pillar, she then tells mirio that she thinks she found the stone they were looking for. As mirio floats up to the pillar and grabs the stone, he tells Kirihai that he has it and then all of a sudden, the entire ruins begins to shake as a giant golem made out of a suit of armor bursts out of the ground with red eyes and then lets out a loud scream. Kirihai and mirio looking at it didn't seem fazed at all but instead they both had a look of bordom. The giant golem then tells them that he is the guardian of the millennia stone that possesses the sand beast and that who ever that were to take it shall pay with their lives, mirio then asks Kirihai if she wants to take out the piece of metal or he should do it. Kirihai then takes a few stretches with a smile on her face and says that it seems like a fun to fight, she says that she hasn't had a proper challenge in a while, so she will be the one to take it on. Few minutes later, the golem was just lying lifeless on the floor as its metal body had been completely ripped into pieces, mirio with his chains floating round his body sighs and tells Kirihai that it wasn't even a challenge at all. Kirihai then draws back her sword and tells mirio that the golem was able to make her draw out her sword, so it was probably strong. Meanwhile in the city of steel which was located in the iron county, shouya(16) was having a sparing match with kazu(18) in an arena which seemed empty. As they both were fighting with close range combat, kazu was telling shouya that his combat abilities has improved really well, shouya who seemed to be having a little trouble keeping up with kazu tells him that he is finding it really hard to keep up with how fast he moves. As kazu was about to kick him, a tentacle comes out if shouya's back and forms a shield around him. Kazu then steps back and says that they have had enough training for one day, shouya then tells kazu that between his combat abilities and their elders sister's harshness its becoming abit frightening. Rin(19) then comes into the arena and tells kazu that he should learn to take it easier on shouya, kazu then smirks and tells her that she is always to soft on him. Rin then gives shouya a bottle of water and tells him to drink up. As shouya drinks up, he sighs in relief and says that he could use some sleep at the moment and then rin tells kazu and shouya that lord Yamamoto(The lord of the iron country) calls for them. As shouya, kazu and rin were in lord Yamamoto's office, Yamamoto who seems to be an old man with long beards tells them that their is an important mission that he has for them. He explains to them that the millennia stone of the sand beast has been stolen, he tells them that their mission is to retrieve it from the criminals who stole it, he further explains that the people who stole it are from the dark sign. Shouya then asks if that isn't that the group kenji their previous sensei joined. Yamamoto then tells him that he is correct and that only three of the members of the dark sign were seen, one with a black hood who can use chains to form objects, the other girl who is very deadly with using sword, and kenji who has infiltrated into the city of steel in search of some precious items. Kazu then asks if their mission is to take them down and Yamamoto tells him that he is precisely correct and their mission is to put them down and return the millennia stone back. As mirio and Kirihai were walking in the waste lands with the millennia stone, Kirihai tells mirio that this mission was a piece of cake and that she wasn't expecting it to be so easy. Mirio who was floating on his board made out of his chain then sense something and tells Kirihai to look out. A blast wave flies out of nowhere and hits them and causes a big explosion in the wastelands. Fortunately, mirio used his chains to form a shield around them to protect themselves from the blast. Mirio then asks who is there and then rin and shouya appear as rin asks them if they are members of the dark sign. Kirihai then asks them what they'll do If they said they were, rin tells shouya to handle the chain user while she takes care of the girl with sword. Kirihai then tells mirio not to get himself killed while she takes care of the cocky bitch. Rin them asks her who she is calling a bitch and then Kirihai gets a devilish smile on her face while slowly drawing out her sword and tells rin that there is only one way to find out. Meanwhile while at an underground dungeon which was very big with monsters laying around dead, kenji was walking inside it as he was holding a scroll. He then hears a voice asking him were he is going to with those scrolls. As Kenji turns back, he sees kazu standing behind him with a serious look on his face, kenji then smiles and tells him that its been too long and asks him how he's been. Kazu then summons his sword and calls kenji a traitor and tells him that he has no right to smile at him, kenji with a smile on his face then tells him that's no proper way to greet his old sensei. Kazu then tells him not to dare call himself a sensei after abandoning the iron country and keeping shouya at a horrible condition. Kenji then gets an evil smirk on his face, kazu who also has a smile on his face tells him that he is going to make sure to end things here and now.
