Water.

The most essential substance on the planet for survival, nothing is capable of living without it.

It can be a refreshing beverage, healing those who come into contact with it. Or, it can drag you into the dark depths of the sea.

Either way, only those who respect the ocean can have the honor of using it.

Patch beach, night

A young boy can be seen on the beach, waiting. He had black hair, blue eyes, a light-blue shirt, black pants, blue glasses, and white shoes. His pants had a picture of a water droplet on his right leg.

Seeing something moving in the water, the boy got into a fighting stance. From the sea, a black beast resembling a giant octopus emerged. It slammed a tentacle into the boy, only for it to be encased in ice before being shattered like glass. The remaining shards then levitated off from the ground and shot themselves into four other tentacles, rendering them useless.

"YYAAHH!" the boy shouted as five bubbles spawned around the black beast. "Take this!" The bubbles then exploded, dealing immense damage. Afterwards, a large icicle formed in the water, which was then immediately dropped on top of the beast. Writhing in pain, the beast failed to defend itself when the boy stabbed a cyan blade into it's body.

Removing the blade, it was shown to be a double-sided scythe made entirely out of blue ice, the most durable kind of ice in existence. He then stabbed it into the ground, causing geysers to erupt from the earth.

The geysers were shot into the octopus's body, making it explode from all the water pressure.

"Hey! Brother!" The boy turned around to see the boy from the Red Trailer yelling at him from the forest. "It's dinnertime and mom wants you to help clean the veggies!" the older boy said. The younger boy threw a shard of ice at his brother, which was just barely dodged. "Suit yourself, Bro. I'm going home for pasta night." the older boy said as he walked back to the house.

Ironwood's office, night

"Headmaster, I have bad news! The Relic of Destruction has been stolen!" an AI told the partially cybernetic man.

"WHAT! How is that possible? We have have guards and security cameras everywhere!" Ironwood asked. He was given the camera footage. From 5:50 to 6:00, the footage was nothing but static.

If only he knew that the person behind this theft was the younger brother of someone he trusted.
