Yuki and Kakeru landed in a building in the city of Hankai, the place is a mess, it is almost impossible to see small houses because of the flood. The water has reached eight meters and the volume is increasing.
Yuki: What happened to the civilians?
Kakeru: They are abandoning the city while we are speaking, but this isn't our biggest problem right now.
An owl appears and lands on Yuki's shoulder.
Athena: I found him! He is at the building on your left at thirty meters from you. He is on the sixth floor! The building is obstructed so I couldn't let you guys land on it and this is the closest building.
Yuki: How the hell we will get to that building?
Kakeru walks to the edge of the building and his ring starts to glow as he kicks the floor and orange energy, flows through the entire place, and half of it is demolished, and a bridge is formed by the parts that have been destroyed.
Yuki: What the hell is your ability?
The man ignores Yuki as he walks on the bridge. The boy tries to follow him but the bridge is rusty and almost collapsing.
Yuki: You sure this is safe?
Kakeru: I won't fall.
Yuki: And what about me?
Kakeru ignores him, and Yuki is forced to follow him, he tries to ignore parts of the bridge falling from a height of 18 meters.
Yuki: Don't look down, don't look down, don't look down.
The owl in Yuki's shoulder looks at him with a smirk and wide eyes.
Athena: Afraid kitten.
The boy pushes the animal from the bridge, and he returns flying.
Athena: I deserved that.
The three of them reach the tenth floor of the building. The place is soaked, old, and falling apart. It is more than thirty square meters with pillars around it and an open place in the middle with a round glass.
Athena: This building was of the "LifeBetter" corporation, they helped the poor people with machines and inventions all over the world. That glass was used to show their new inventions. But the enterprise declared bankruptcy after the war collapsed. The CEO was a good friend...
Yuki tried to pet the owl out of pity for her, but she turns away from him. As they were speaking Kakeru is crouched on the floor looking for something with his eyes closed.
Yuki: What are you doing there?
Kakeru: Math.
Yuki: What? And why are we on the tenth floor?
Kakeru: You will discover right now.
The man punches the ground and orange energy is spread through the floor and it starts to fall with them standing on it. They fall to the sixth floor still standing. Suddenly in the rubble, a man appears with red eyes covered in a water veil and a water trident starts to look directly at them, furious and roaring, his roar looks like from a sea lion. The water in the place starts to forms dozens of blades pointing at Kakeru and Yuki.
Kakeru laughs in excitement as his ring starts to make an agonizing sound throughout the entire place shaking the water and making Yuki covers his ears.
Kakeru: Let's start this party!
As he laughs like a maniac.
