Due to the encouragement from the remnant consciousness of his late comrades. Finally Kiba was able to attain the Balance-Breaker which he had not been able to use all this time.
"Balance-Breaker" Sword of the Betrayer "!" A sword with both holy and demonic element.
"Valper Galilei? With this sword, I will avenge my comrades' deaths! "said Kiba.
Xenovia, Griselda, Valper and Siegfried looked really surprised. After they saw Kiba Balance Breaker the Holy Demonic Sword.
Holy Demonic is an impossible thing, because it was a fusion of two opposite elements. They are all couldn't believe it, Kiba managed to do something impossible.
"Si-Sister Griselda is it possible to fusion a two opposing elements like that?" Xenovia asked.
"That's impossible Xenovia." Griselda replied. "Kiba Yuuto Balance Breaker, the Holy Demonic Sword is probably a bug in the Sacred Gear System!"
"Ho… Holy-demonic sword ...? That was Impossible! The polar opposite of two things cannot be merge!" Valper feel really shock, after seeing what happen to Kiba sword. It making him off guard. "The reason the two opposite element can be merge must because the death of ..."
When Kiba was about to stab Valper without intending to kill him. Suddenly a light sword pierced Valper's body from behind, making him died instantly.
Siegfried stabbed Valper from the back, secretly with the intention to make Valper not saying something that unnecessary.
"You talk too much old man," said Siegfried. "I hate a people who talk to much!"
Kiba was shocked, when Siegfried killed Valper silently. Why did Siegfried have to kill his own comrade like that?
"Siegfried! Why did you kill him!" Shouted Kiba.
"He talks too much," replied Siegfried. "And I really hate him from the beginning!"
Xenovia and Kiba probably didn't realize the reason why Siegfried killed Valper. But Griselda who have more experienced than Xenovia and Kiba could sense something was off, why did Siegfried suddenly kill Valper like that? Plus Valper's last words which made Griselda feel suspicious. It seemed that Valper knew a reason why the Holy and Demonic elements could merge together, but Siegfried didn't want Valper to say it so he killed Valper.
"The reason you killed Valper doesn't make sense Siegfried," said Griselda. "You killed Valper like that, it must be because of the last words Valper would say!"
"Sigh, your instincts are sharp as always Griselda," said Siegfried. "Your guess is right, the thing that Valper will say is the reason I killed him, because if he says 'that', thing. I'm afraid that you and that little girl will lose you're reason to fight. That's why I killed Valper so he couldn't say it."
"Whatever Valper will say, I will not lose my fighting spirit!" Shouted Xenovia. "Saint Peter. Saint Basil the Great. Saint Denis. Please hear my voice.In the names of the saints whom reside within this blade, I will release it Durandal! "
Xenovia took out her Durandal from the pocket dimension and immediately attacked Siegfried.
Siegfried didn't expect that he would fight against the new Durandal user. The previous Durandal user Vasco Strada was an idol for him, this was a good opportunity for him to compare whether Xenovia could use Durandal on a level of Vasco or not.
At the same time Griselda and Kiba also attacked Siegfried.
Siegfried doesn't look scared or afraid. Instead, he smiled sarcastically while taking out his Sacred Gear the Twice Critical, after that he immediately said the same words as Kiba before.
"Balance Break!"
Behind Siegfried's back appeared 4 additional hands, and in each of them was a sword with a demonic element.
Kiba, Griselda and Xenovia's attacks were blocked by Siegfried at the same time, thanks to the four draconic arms that appeared from his back.
Seeing their attack is stopped at the same time, Kiba, Griselda and Xenovia felt quite shocked. The three of them didn't expect that Siegfried's Sacred Gear Balance-Break made him have 4 additional arms.
"Even if you all attack me at the same time, it will all be useless!" Siegfried said. "My Twice Critical Balance-Breaker Chaos Edge Asura Ravage gives me 4 extra arms, plus my six demonic swords, you're all can't beat me!"
"Twice Critical's Balance Breaker sub-species huh," said Griselda. "Plus six high level demonic swords, this is really bad."
"Let's just fight him at the same time, Sister Griselda!" Xenovia said. "At least we can keep him at bay!"
"I agree with Xenovia-san," said Kiba. "When I clash a swords with him earlier, I could feel Siegfried's swordsmanship is almost equal to Emiya-san's. To be fight him alone is impossible, at least the three of us have to fight him together so we can fight him on the equal ground."
"Then let's fight him!" Xenovia said. "If we just talking like this, it won't solve any problem!"
Kiba and Griselda nodded their heads in agreement. Xenovia, Griselda and Kiba dashing at the same time and charged their attack to Siegfried.
Siegfried doesn't look scared or scared he smiles like a crazy person then laughs out loud.
"Ahahahahaha you three want to attack me at the same time?" Siegfried said. "Very good! This is what I was want! C'mon attack me!"
As a battle maniac, fighting 3 strong people at the same time is something fun for him. There was no way he would miss the rare opportunity that lay before his eyes.

Rin, Luvia, Rias and Akeno managed to defeat the two Cerberus. But the four of them looked very tired.

At the same time, when Arturia and Shirou were fighting Kokabiel.
Arturia who was still not used to her new body looked really exhausted against Kokabiel even though she was using Excalibur.
Shirou attacked Kokabiel using the sword he launched from the Gate of Babylon along with Kanshou and Bakuya in both hands to attack Kokabiel. Plus Arturia who joined him to attack Kokabiel, making Kokabiel feel pushed litlle by little.
"Tssk, fighting two people with Ultimate Class level power at the same time is really troublesome!" Kokabiel said. "But I haven't felt this adrenaline-pumping battle for a long time! I'm really satisfied to be able fighting both of you at the same time!"
Shirou and Arturia only suffered minor injuries, after fighting Kokabiel for almost 5 minutes.
But the situation was different from Kokabiel's, one of his 10 wings had already been injured and can't be used after being hit by the Excalibur. His face, limbs and other wings were covered with scratches from Shirou attack. His body was full of injury, but Kokabiel didn't look in pain. He even didn't fight Shirou and Arturia with hate or anger, he was enjoying his battle with Shirou and Arturia in a calm manner.
"Hah, hah, hah, this body is really weak," said Arturia. "My stamina hasn't returned to what it used to be, my attack power has also decreased by 75%!"
"If you train your body again then slowly your ability will return to its peak, Arturia," said Shirou. "So you better rest first, I will be the one who will fight with Kokabiel."
"Be careful when against him Shirou, he's not serious at all when we fighting him," said Arturia. "Plus his incredible composure when fighting the two of us shows he's very experienced on the battlefield!"
"I know Arturia," said Shirou. "I will be careful against a dangerous enemy like him."
While Arturia and Shirou were taking breaths, Kokabiel was looking at Siegfried stabbing Valper in the back.
"Valper you are a great person, and a smart scientist, you can make a right conclusion why that little devil Balance Breaker is so unusual," Kokabiel said. "But you must learn to shut your mouth a little, that's why you die. "
Shirou who also looked at Kiba and heard Kokabiel's words immediately realized what Kokabiel's meant.
He laughed a little in his heart, what if Kokabiel found out that 'He' who was the 'Father' of Kokabiel had not died at all.
