Keira and Higarashi then stopped running and stood before Xyon, while Weim stood behind the dark blue haired girl.
“It's late at night, Xyon, why did you ask me to bring them here?” ask Weim.
Xyon suddenly raised his right hand and a cosmic sword appeared within his grasp. He directly pointed the cosmic sword in front of Keira until Higarashi and Weim were surprised by the action, but not the girl who was silent while looking at Xyon with a serious face and sharp gaze.
“Xyon! It's late at night!” exclaim Weim, “Can't you do it tomorrow? They must have been exhausted after the party!”
“Shut! Tired up? This was the result of both of them, and Sey became his victim!” exclaimed Xyon with a face that looked annoyed now.
“Do you think it's just Uncle Sey? Then, what about my foster family?! Don't you care about them either?!” asked Keira in a high tone.
Xyon this time brought the sharp tip of his cosmic sword close to Keira's nose.
“Prime Minister Xyon!” exciting Higarashi, “Stop now!”
“I ... are tired of all this. If you can't show me how strong your Crossbreed side is, then you .. are not worth fighting for!” exciting Xyon.
Keira now began to understand what the Prime Minister of Palladina wanted. The two eyes of the girl suddenly changed color to dark blue.
"Double Cross Lighting!" he exclaimed, and two long cosmic swords that were light blue then appeared within each of his hands.
“Keep away both of you!” xyon exclaimed after that, then he started attacking Keira after Higarashi and Weim had already walked back and stood a bit away from her and the dark blue haired girl.
Keira did not remain silent. He withstood all the attacks Xyon had launched on him, however, it did not stop Xyon from attacking him.
“You'll never understand, Uncle Xyon! You just lost Uncle Sey, and you think you're the only one who's sad! I ... I've lost a foster family that has cared for me since childhood, even giving her love to me! Then, you called me to come back here just to avenge you for those Silverians, didn't you?” shouted Keira while continuing to resist the attack from Xyon.
“You'll never know what it's like to be an immortal, Keira!” xyon exclaimed, however, because he was too ambitious, it caught him off guard and the girl finally managed to injure his right arm.
“Argh!” yelled Xyon in pain.
They now stopped attacking each other and stood facing each other, with cosmic weapons not directed at their respective opponents.
“You ... are still less able to control those two cosmic swords. I'll teach you how to fight and defend, to train the Crossbreed strength you have, while Weim, Arex, train, and Nordian will teach you everything about this Metal Galaxy along with the rules you should know,” said Xyon quietly.
“Wait, Uncle,” exclaimed Keira, with both eyeballs that had now changed color to light blue as before and both of his cosmic swords then disappeared after that.
Xyon stopped his steps. Keira then raised her right hand before Xyon and a light blue mist suddenly enveloped the Prime Minister's body from Palladina.
“Keira,” murmured Xyon.
He looked back and the light blue fog slowly disappeared. The incision on his right arm had now disappeared and there was no more pain he felt. Xyon then looked at Keira as she frowned while the girl then lowered her right hand.
“I'll take you to the Light Chamber to recharge your light energy. Just save that antimatter energy, because .. even though we're here to make antimatter, however, the antimatter we're producing is not pure antimatter that can last as long as you have, Keira. The artificial antimatter will soon be destroyed once it comes into contact with the material,” Xyon said.
Keira then looked at Xyon with a sad face, as did Xyon who noticed the dark blue haired girl with a flat face.
“I can feel the sadness you are feeling, Uncle,” Keira said.
Xyon just let out a long sigh, then said, “Life must continue, right? From now on, you'll be a different girl, Keira.”
The Prime Minister of Palladina then turned to Higarashi, and looked at him with a serious face, then exclaimed, “Hey, you, young man! You should visit here often, because I must also teach you how to use that cosmic weapon! Your job is to protect Keira, as a consequence of the decision you are taking right now!”
Higarashi smiled broadly after listening to the order, then he shouted, “Alright, Prime Minister Xyon! I won't let you down!”
“This is all so that you can defeat the Silverians later. I.... will not let them act any further than this! Just wait, that guy named Dovrix will soon get my revenge!” muttered Xyon in his heart while still staring at Higarashi.
During the forty-day mourning period inside the Palladina Planet, Higarashi is seen visiting every morning until night to learn to use cosmic weapons along with Keira. He will return home after getting enough lessons that day. Not infrequently, Weim and Arex, even Nordian also invited him along with Keira to read cosmic books in the palace library.
The three senior generals, in turn, taught everything about the Metal Galaxy and all the rules of the kingdom. Although Keira seems to have difficulty understanding several times, Higarashi will help her immediately. Not only does it teach about general knowledge, but it also invites Keira and Higarashi to patrol space, while learning many things.
After the forty-day period of universal mourning was over, Xyon asked Arex, Weim, and Nordian to harden the practice and expand the lessons for Higarashi and Keira, because of his grudge against the Silverian Planet which is increasingly becoming, especially with the death of Sey on that day.
They all became very close. Not only did Xyon teach him how to fight and survive, but he also allowed Keira and Higarashi to patrol space. He also ordered some maidservants to give the dark blue-haired girl a lesson in manners and ethics as a royal princess.
But one day, Arex meets Xyon in his private study. The Prime Minister was seen sitting on the sofa while Arex stood in front of him.
"Why didn't you tell them anything about what really happened to the Silverian Planet in the past?" ask the Senior General.
