Zack and Sebastian finally agree to become the Hero of Valhalla because if he becomes a Hero, it will be followed by a war against the devil.
Which is where the devil is their goal to defeat. Here Zack, Sebastian accompanied by several soldiers began to go into the depths of the forest to look for mythical monsters.
As they began to enter the mythical monster area, it was as quiet as there was no life. As they searched and searched the entire corner of the Forest they found no monsters at all.
it was also getting dark, finally they decided to go home alone.on returning they were shocked because the Valhalla Kingdom was destroyed and in the middle of the Kingdom building they felt a very Gripping and Scary Aura.
The aura can make the Soldier who was with Zack and Sebastian began to faint and lay. Here Zack and Sebastian are not affected by the induction effect.
The two of them began to enter the Kingdom and search for Hero Rei. while in the middle of walking, in the settlement they both saw that Hero Rei had died with very severe injuries.
here they were both very angry and their emotions began to overflow. They swiftly entered the kingdom, but it was not that easy, many monsters were already waiting in front of the kingdom.
Here Sebastian's intention is to give up all rare monsters to handle himself, and Zack continues to defeat Mythical monsters, otherwise the monsters will not die.
Because monsters depend on their masters, while the masters of the monsters they face are Mythical monsters, namely Medusa.
Zack here disagrees because Sebastian's intentions are very dangerous, here Zack starts trying to kill one of the monsters, and as a result Zack's attack is useful for killing rare monsters, medusa's rare monster should have depended on Medusa herself.
Zack's magic directly hit Medusa itself. Here Zack immediately wanted to end this all by way of issuing a Lightning Rain that could cause the earth to shake.
"I'll destroy you, you medusa! I will bring out my Lightning power!! " Said Zack while issuing an attack.
Zack's attack can even make the sky dark instantly, the rain is very heavy and the peak is a black lightning bolt that strikes part of the Kingdom.
But it was useless because Medusa was an ingenious mythical monster, she directly attacked using her laser so that Zack's black lightning could not hit her.
Without a second thought sebastian instantly made a sword from the fire and shot towards Medusa, here Medusa managed to dodge, but Medusa was still hit by a slash even if only a little.
Sebastian is exposed to blood from Medusa, whose blood Medusa can cause the effects of poison to weaken his strength, Sebastian's stamina is severely lacking due to being exposed to Medusa's blood.
Sebastian was finally deployed to fight one of the medusa clones, Sebastian was overwhelmed by the blood of Medusa who continued to make his strength decrease.
Zack will also not stay silent, here Zack uses tactics to attack from a distance so that the blood released by Medusa does not hit Zack.
But still, Medusa's speed was as fast as lightning to make Zack too overwhelmed. But Zack has a chance to target the jewel of Medusa in the head.
Zack and Sebastian are here retreating to lure the Medusas, after being lured, to the bait, Medusa's legs are held by Sebastian's earth element and immediately plus another attack that is Zack's dark hammer which immediately shot and destroyed Medusa's Head.
"Your attacks are useless, HIHIHIHIHI, I am not a mythical monster anymore, but I am a supreme monster, You will not be able to defeat me, I have completely depended on my Master the devil. by the way, Oi red-eyed man, is your friend Hydra?, he has been banished by Mr. The devil, for having entered into a contract with you!!, The Devil does not attach much importance to it because the Hydra is a weak being! HIHIHI" Medusa said as she sneered
"Whispering you Medusa, do you want me to kill you!? don't talk anymore or I'll kill you!! " Say Zack in anger
In the middle of the fight. Suddenly, there was an extremely powerful Aura, trees, plants, animal animals started to die of rotting due to that aura. He was The Devil, with his form being a white-haired Evil Monster-like creature.
The devil came to retrieve the body belonging to the Hydra and wanted to absorb all the power of the Hydra.
"HAHAHA, As there is a fight, I will disturb you guys a little, I just want to take Hydra's body and absorb its power, so that I can get stronger." The Devil said
The arrival of the devil even makes the surrounding area destroyed, existence The devil itself can even change the laws of nature and reverse the volume of destiny in the world. therefore the devil will not linger here long.
if the human world was destroyed, then the world belonging to The devil would also be destroyed, because the human world and the monster world were interconnected, so if one was destroyed then the other one would also be destroyed.
Here Sebastian fainted from the Aura of The Devil himself, Sebastian was immediately taken away by The Devil.
therefore Zack wants to attack the devil but that is impossible, because The devil is very strong, Zack attack is not effective against The devil, but it is impossible, even Zack's attack is distorted by the devil's always-on barrier where the devil is.
The devil also automatically stops time if any attack comes close to him, but for Zack this is useless because his Darkness power can move if time stops.
Zack forgets that his opponent was Medusa, so Zack langsug is exposed to Medusa's attack which resulted in Zack's entire body being exposed to poison and rotting.
The dying Zack is left behind by The Devil.
"BASIC snot boy, touching me just can't, you die and rot in hell!, Oi Medusa, take care of him!, you've been destined to kill him." The Devil said
"Ready sir" Medusa said
Finally the destruction in the world began to stop, Medusa who was destined by The Devil to defeat Zack. Here Zack is very helpless and the chances of Zack winning are only 0% not even having the slightest chance.
But Zack remembers his memories with Sebastian when he first met in a cave, got acquainted, even entered into a contract together, and defeated monsters together, they both also made a combo called the duo of death.
From then on the Spike of Power that was in Zack's body began to activate. The whole world shook with the surge of all Zack's power. Sebastian's powers, once sealed within Zack's soul, are active. Mixed with Zack's dark forces, they finally integrated and caused Energy Zack to become very large.
Even the Rare monster belonging to Medusa instantly died and was destroyed due to the impact of the aura from the extremely Strong Zack.
