"Explode." Tasha's voice resounded in Kai's ears, followed by six explosions.

Kai turned around and shouted. "Tasha. You…"

"I am sorry, Kai. But I believe this is the best. As you promise earlier, right? I don't need to hide it again, right? Since I only have two or three months until graduation, I think this is the time I can finally release all my power." She smiled as the giant body was launched to the magical beasts, sweeping them to death.

Kai closed his eyes for a second and sighed. "I understand. Don't worry. If necessary, I would do the craziest thing ever."

"Thanks." Tasha smiled as she landed on the ground.

Rain almost forgot the fact that Tasha was also one of the S Rank magicians. Even though her strength seemed to be on par with Michelle, the talk earlier made him realize that might not be the case.

"I will be helping you fight the starfish."

"Yeah." Kai smiled as she appeared next to him, facing the golem that was trying to get back up.

Their shoulders touched as if they leaned on each other. Tasha aimed her bow toward the giant while Kai pointed his right sword forward.

He recalled his past and couldn't contain his smile. "It's been a long time since we last fought together. I will be counting on you."

"Leave it to me." Tasha smiled. Instead of jumping forward, Tasha teleported Kai to the back of the giant while she released her arrow toward the golem's head, where she believed the starfish hid.

You…" Serta raised his hand, planning to stop the arrow with his hand, but he suddenly felt a powerful blow behind his knee.

Kai smiled as he released enough strength to bend the knee, allowing Tasha's arrow to slip past the finger and hit the head.

However, Serta, who saw the arrow from point blank range, found a small marble filled with a white mist.

The moment it hit the head, the marble popped out, creating a massive explosion.

"Gah!" Serta lost his body balance again as he fell on his back due to his body's form, especially after Kai hit the back of his knee.

Michelle smirked as she might be the only one other than Kai and the Carter Family, who knew about Tasha's real magic. As the name implied, it was bonafide sealing magic. What she sealed earlier was air and compressed into a small ball.

The burst air created a different type of explosion than that of Ayaka's. It didn't have a powerful fire or any other things because it only had a shock wave that was capable of launching the giant golem into the air.

On the contrary, Sofia, Ayaka, and any other people who usually came with Tasha and Kai gasped. They didn't know what her real power was, but it was indeed powerful.

"Michelle, what is that?" Sofia asked as she couldn't contain her curiosity anymore.

"Guess." Michelle stuck her tongue out before continuing her own battle with the turtle.

Kai already arrived on top of the golem's body and struck the head again, trying to crack it.

"Watch out." Tasha smiled as she landed next to him with five small compressed air marbles and used the Teleportation Magic to send both of them away from the golem, leaving the five marbles to explode right on the head.

Boom Boom Boom.

"We need to crack that stone."

"Elder Rapakha was similar to this guy, you know?" She smiled.

"Ah, do you have a plan?" Kai asked.

"Yeah? I don't know if it works, but I really need your help."

"Hmm…" Kai narrowed his eyes when he heard about her plan.

"How about it?"

"Let's try it." Kai nodded in agreement as he jumped next to the golem head and snapped his finger, creating a disturbing high-pitched sound.

"Argh!" The pain began spreading all over his body as his ears.

Before he could get up, Tasha already created a few more marbles, exploding them to launch him to the air only to land again. However, the giant body moved on the land and even almost rolled on the ground. It killed around a thousand beasts in one fly, so Tasha's plan was to do it continuously, using him as their own weapon.

After all, it wasn't like Serta could easily control the giant body.

Kai smiled and snapped his finger again, harassing him from the point black range. Wherever Tasha sent Serta's giant body, Kai would follow.

"Tch." The turtle clicked his tongue and planned to help Serta, but both Michelles appeared in front of him, ready to jump ahead to stop him. With their combination, he realized that it was impossible to escape easily.

He looked around, trying to find something that he could exploit to turn around the situation. He turned to the octopus and found that Rain sealed him inside a box.

"What should I do?" The turtle didn't know what to do anymore other than retreating. Their condition was in stalemate, and sooner or later, Serta would die. It would be such a big loss if that happened. Yet, all the possible plans in his head would end up sacrificing Serta.

The constant harassment and Tasha's explosions really wore down his endurance. He never thought that the sound Kai produced would be that big of a deal.

In fact, he planned to return to his normal form because this giant body turned out to be his greatest setback during the fight. Unfortunately, he realized that the moment he returned to his previous self, Kai and Tasha would have severely injured him first before he could do anything.

Nonetheless, the result wouldn't change. Tasha and Kai kept harassing him until they got the opening they desired.

Crack.

The moment she found a small crack, Tasha leaped to the sky as her body was covered by lightning. She raised both hands and created several magic circles, turning the blue sky to dark.

Thunder started ringing on everyone's ears as they couldn't believe what she just did.

"Don't tell me…" The turtle gritted his teeth. "She is going to call lightning? This is already beyond what a normal can do! Is she…"

He hesitated to complete his sentence because Kai should be the one to be the protector, not her. In other words, they must have missed something important that no one knew other than herself and Kai Carter.

He raised his shield and summoned a translucent barrier in the sky, planning to stop the lightning, but Kai used the Sound Blast, flew to the sky, and struck the barrier with his Super Sonic Sword.

Unlike before, he changed the direction of his Sonic Boom to the back, allowing him to increase the penetration power in that one thrust.

Still, Kai had done it a few times during the practice with Ria Ross and all of them ended up with him getting injured.

There was one difference though. This time, Kai wore his exoskeleton. The Sonic Boom was shredding his clothes and grazed him here and there, but Kai was determined to destroy the barrier.

He used his Sound Blast once again to boost his strength until finally, a huge crack appeared on the barrier as Kai shattered it like that of glass.

He raised his vision and saw that the lightning was about to be fired.

"Sound Blast."

Using one last magic, he evacuated to make sure that he didn't get struck by lightning.

"Here I go." Tasha activated the magic circles. "Lightning God's Wrath."

Blue lightning struck forth, hitting the magic circles in succession.

"No!" Serta tried to summon a roof to direct the lightning elsewhere, but Ayaka decided to interfere.

"Scarlet Explosion!"

Boom.

The explosion shattered all the rocks that were supposed to be his shield.

"No!" Serta screamed as the lightning struck him.

Just like natural lightning, it disappeared in an instant, unlike how it came down. The damage was also similar to how the lightning split a tree into two and other similar videos spread all over the internet.

And this time was no different. The rock was crushed by the lightning, revealing the real body of the starfish.

When Kai saw that chance, he quickly went on top of the giant body and struck his chest.

Suddenly, the turtle's voice resounded on the battlefield.

"Serta. We need to leave right now. The situation has become unfavorable to us, especially since we are on the land. Our power has been reduced by fifty percent, but you…" The turtle didn't know how to complete his sentence. For him, it was too cruel to ask Serta to sacrifice himself.

However, Serta replied without hesitation. "Old man. You need to live. Since I am the useless one during this fight, I will fulfill my last duty."

"No. You are not useless. Your opponent is just too strong."

"No need to comfort me, old man. Now go…" Serta's body began shining.

"!!!" Kai widened his eyes in surprise, knowing that he would probably do something like a suicide bomber. After all, he had experienced it back in South America.

"Get away from here!" Kai shouted and returned to Tasha before carrying her out of the battlefield. "All soldiers. Retreat right now! He is doing something big!"

Tasha knew that she wouldn't be fast enough to send him away with her Teleportation Magic due to the size. Even the last teleportation required a few seconds. Before that time, the golem would have finished this strange magic.

Seeing that the Octopus and Turtle were about to get away, they knew that whatever he was going to do would be too big for them to handle.

They started retreating along with Kai. Even Rain released the octopus and summoned a barrier to protect the soldiers.

"I have never thought that there would be a time I need to use this..." The light glowed brighter.

"Eterna Grana."
