Chaos

Soon after silence settled over the city they began hearing screaming. It sounded like the screaming was coming from every direction in the city. Soon after they noticed a blood red smoke gathering over the city coming from different sections of the city.

Damn I thought we had more time Usiel said.

What is going on Mihael asked sounding worried. 

The cult has reached the final step of their plan which is opening a portal to the hell plane letting forth a flood of demons into this world. Raziel explained. 

What can we do to help Aeden asked. 

Nothing, you two need to go home before Usiel was saying before being cut off.

A loud sound of shattering glass echoed through the city and as they all looked towards the source of the sound they saw what looked like the sky cracking apart. The red smoke then gathered around the crack forming a magic circle creating a portal to the Hell plane. 

Then a hoard of demons began pouring out of the crack like water.

You two need to go now Usiel said. Go home and use the keys we gave you. 

But doesn't that mean you are going to leave? Mihael asked.

Yes and we are sorry but we are going to have to leave you. The only way we can seal the crack is to unseal our powers which will result in us getting removed from this world Raziel said.

Just know we will always love you and we never wanted this to happen Usiel said. 

Both Raziel and Usiel hugged their sons saying their goodbyes as Mihael and Aeden cried. 

Soon after they turned around and took off their rings letting out their wings and other features. Then they looked at each other and nodded as their bodies mana began to increase and their features began changing. They both gained a crown on their heads. Golden for Usiel and Crimson Black for Raziel. Then they grew an extra 3 pairs of wings. Their mana began shrouding their bodies forming an armor around them. Then they began manifesting their weapons.

Raziel had a staff form in his hand. It looked like vines were growing from the base to the top where they surrounded a clear orb that had a smoke circling around it. The staff had runes carved all around the staff which exuded a powerful pressure.

Usiel had a sword form in her right hand with a shield in her left hand. Both were a silver and gold color with various gems of different colors over the shield and sword. The gems on the shield formed a magic circle with various runes around them and the sword had runes along their blade with the gems mixed in with the runes. 

Right after this while crying both Raziel and Usiel turned around and told Aeden and Mihael that they loved them before taking off towards the sky. 

Mihael was on his knees on the ground crying. As Aeden was standing next to him.

Come on Mihael we need to go before the demon hoard arrives Aeden said.

Grabbing him and trying to get him to stand up Aeden kept trying to get Mihael to head towards their house but he wouldn't move.

Mihael was just sitting on the ground while muttering. He was crying but his face seemed emotionless.

Why does this have to happen. Mihael muttered over and over as his eyes slowly became black and a deep black aura began flowing out of his body. 

Aeden kept trying to move him as the demons were moving closer. Seeing as he couldn't move Mihael he stood in front of him and drew his sword determination in his eyes to protect his brother. 

Mihael looked at Aeden before overcoming his dark emotions and standing next to him. 

I won't let you sacrifice yourself for me just because I am weak. Mihael said. 

Grabbing Aeden's hand and drawing his sword as well both of them began to prepare to fight the hoard seeing as they had no more time to run away. 

Right after they heard a sound of a chain being dragged and then shattered as a golden aura came out of Aeden with Aeden's eyes glowing golden. Then they heard the system.

<Seed Of Divinity Seal Has Been Loosened>

<Soul Resonance Detected><Beginning fusion>

<Activating System Battle Mode>

Right after both Aeden and Mihael felt themselves slowly melding together. Their bodies turned into balls of light and fused together. 

They became one with two sets of eyes two sets of wings and wielding two swords in their hands while another two hands sat idle. The horns on their head grew longer and looked like a crown as the eye on their forehead opened spreading runes on their bodies. 

<Battle Mode Is Active>

<Time 10 Limit Minutes>

<All Kills Will Be Automatically Absorbed And Stored For Future Upgrades>

<Happy Killing Hosts>

Mihael and Aeden smiled a malicious grin excited to get revenge for the demons ruining their peaceful life.
