The countless Blast Bombs flew towards Astra, but the Unicorn simply snorted before teleporting away from his location.
However, Eiko had already expected him to make the same move, so she scattered all the Blast Bombs across the arena and detonated them at the same time.
This caused a chain reaction to take place, and soon, a series of explosions shook the entire arena.
A thick dust cloud appeared in the surroundings, but Eiko knew that this kind of attack wouldn't be able to reach the Unicorn, whom she treated as her rival.
With a wave of her hand, the dust cloud disappeared.
At the far end of the arena, Astra hovered in the air, with a dome of light protecting him.
The Unicorn then eyed the Fairy Princess with a serious expression before flying high up in the air.
It then raised its horn toward the sky, creating dark storm clouds above the arena.
With a neigh filled with defiance, Astra summoned countless lightning bolts which rained down upon Eiko.
He intended to finish the battle as early as possible because his opponent made him feel that the longer the battle continued, the less chances he had of winning.
However, just as the countless lightning bolts were about to hit their target, all of their trajectories changed, as if being attracted by something.
At the center of the arena, a five-meter tall Thunder Slime absorbed the countless lightning bolts, resulting in its entire body glowing white.
The corner of Astra's lips twitched after seeing the Argonaut-Ranked World Boss that appeared out of nowhere.
He then neighed angrily at Eiko which meant, "Girl, this is a one-on-one battle. Why are you summoning World Bosses to our fight?!"
Eiko, who could understand almost all the languages of the Beasts in the world, smiled fearlessly.
"I don't fight one-on-one battles," Eiko replied with a smile.
Lux, who was watching on the stands, nodded his head in satisfaction.
"That's my girl," Lux said with a smug expression on his face.
Clearly, he approved of Eiko's way of fighting, which resembled his own.
Iris and Cai, who were seated beside him, didn't know whether they should laugh or cry at the way Eiko and Lux handled one-on-one battles.
The Thunder Slime then growled in anger as if it didn't like Astra's treatment of its mistress.
It then leapt into the air, turning into a blur, and charged at Astra with great speed.
Just as the Unicorn was about to use its teleportation again, the space in its surroundings seemed to distort, preventing the Unicorn from breaking free from the space created by the Argonaut-Ranked World Boss Thunder Slime.
Thunder Slimes not only specialized in attacking their opponents with Lightning Bolts, but they also had the ability to distort space, creating booming shock waves that was followed by roars of thunder.
Astra was quick to react, once again summoning a barrier to protect himself.
The moment the Thunder Slime smashed against Astra's barrier, a loud thunderous sound ensued, making the students of the Academy cry out in shock and fear, due to how loud and scary the sound was.
Astra might be strong, but his strength was only equivalent to that of an Argonaut-Ranked Alpha Monster.
If the Unicorn were to be matched with one of Lux's summons, he would be equivalent to the Half-Elf's Nightgaunt, Shax.
The barrier didn't break, but the Unicorn was blown away, smashing into the corner of the arena, where a barrier was erected, preventing anyone from escaping the battlefield.
The Unicorn then crashed to the ground, making Iris clench her fist.
At the end of the day, Astra was still her Guardian Beast. As a Beast Summoner, she had full faith in her friend and protector, who had accompanied her in many dangerous situations.
As if sensing her gaze, Astra looked at the stands where Iris was seated. The Unicorn then propped himself up from the ground and neighed loudly.
"…He is undoing his seal," Iris said with a serious expression on her face. "Astra is now going to fight for real."
The Thunder Slime, who had no idea what Astra was doing, didn't give a hoot and once again charged at his opponent with the intention of beating the crap out of him.
At that exact moment, a blinding light erupted from where Astra stood, making everyone briefly cover their eyes.
A loud explosion followed as the Thunder Slime collided with the brilliant light.
When the light receded and everyone was able to see again, they saw the Thunder Slime crashing toward the opposite end of the arena, forming a crater around where it landed.
Eiko narrowed her gaze as she looked at her rival who had transformed into a demi-human creature.
A handsome man with long white hair looked at Eiko with a solemn expression on his face. He had the wings of an angel, and the golden horn on his forehead glowed faintly.
He was holding a sword in each hand, which made him look like an angel that had descended from the heavens to punish those who defied heaven's will.
Astra's strength had now risen to the peak of an Argonaut-Ranked World Boss, giving him a slight advantage over the Thunder Slime that Eiko summoned.
Suddenly, a giggle reached everyone's ears.
Eiko, who was currently in her Fairy Princess form, giggled as if she found something very interesting.
A few seconds later, she flew towards Astra with a fearless grin on her face as if challenging him to fight in close combat.
Astra, who had already reached the limit of his patience, flapped the wings on his back and met Eiko in mid-air.
He then swung his sword without mercy to the adorable little girl, who had repeatedly pestered him to fight.
Now that he had transformed into his Ultimate Form, he decided to teach the annoying Fairy Princess a lesson she would never forget… or at least, that was what he meant to do.
When Eiko and Astra were only a few meters away from each other, a five-meter-tall Skeleton wielding several weapons in each hand appeared behind Eiko.
It was none other than Eiko's Corpse God, which she had learned to use in combat when Lux was training with Hereswith inside the Necromancer's Ancestral Lands.
Just like her Papa, Eiko had learned the skill Death God's Aura, which created a crimson mist that manifested around the Corpse God's body.
Astra, who initially thought that the Fairy Princess was courting death by challenging him in close combat, now faced the Corpse God, whose role was to protect its Master from any kind of attacks, no matter what form it took.
"Is this really a Slime?" Alicia asked Vera who was seated beside her. "I've never seen Slimes fight like this."
"She's not an ordinary Slime," Vera replied with a smile. "She's my grandson's and granddaughter's Baby Slime. Also, she calls me Manma."
Clearly, Vera also thought of Eiko as an important family member, making Alicia rub her forehead as she tried to digest the information she was receiving.
The beautiful secretary of Barbatos Academy then glanced at the Half-Elf who was watching the battle from the stands.
She was wondering what kind of food he was feeding Eiko, and she wished to know the secret to raising a Baby Slime, who was just as strong and cute as the one in the arena.
Even Alexander, who was watching from his VIP seat, didn't expect Eiko to have such high fighting prowess.
To be honest, he didn't think too highly of Eiko in the past. For him, a Slime was only a Slime, and couldn't be treated as a Rare or Unique Monster.
But, after seeing this battle, his impression of the Baby Slime, who was always perched on top of Lux's head, changed by leaps and bounds.
Maximilian, who had secretly come to investigate the commotion, was also shocked by the things he witnessed in the arena.
Similar to Alexander, he only thought of Eiko as a pet. But after seeing the battle, he realized how wrong his first impression was.
