Prologue
On the road; raining

A girl is running on the road with a cloak covering her face and body.

'I have to get away!' She thought and hears a motorbike is coming closer to her and she hides away into the forest near the road.

She hides there for ten minutes from the rider of the motorbike and that person passes away from her location. She then decides to come out and begins to run again.

~A few days later~
At a house

The girl is slowly walking on the road from fatigue and she gets near a house by the well. When the door opens, a young man comes out with a bucket and sees her. The young man has brown hair and eyes and wears a black shirt, blue pants and black and blue shoes. The girl then collapses on the ground, making the young man to drop the bucket and run towards her.

"HEY! Are you all right?" He asks and shakes her. "Get a hold of yourself!"

The man continues to shake her, making the hood to fall showing the girl's blue hair and she wears a blue dress that goes down to her knees. The man looks around before looking at the girl again.

"For now, I should bring you to my house." He says and carries her to his house.

~An hour later~

As the man watches the girl sleeping on the bed, the girl stirs and slowly opens her eyes.

"Are you awake?" The man asks and the girl looks at him.

"Who are you?" She asks.

"Oh sorry. I'm Takeshi." He introduces. "And you are?"

"Mizuki..." She answers and starts to get off the bed, but she wobbles.

"I think you shouldn't be moving." Takeshi tells her. "You look really exhausted when I saw you collapse like that. We're you running away?"

Mizuki looks down and didn't answers to Takeshi's question and he scratches his head.

"It's fine if you don't answer." He says.

Takeshi then sees something sparkling between the gaps of the cloak and looks closer.

"Hey, there's something sparkling there." He points out, causing Mizuki to widen her eyes. "I wonder what it is..."

He opens the cloak and sees a blue gem on her right arm and widens his eyes before he looks at Mizuki.

"Could you be an Edel Raid, Mizuki?" He asks and she slowly nods without looking at him. "Your gem is really pretty." Mizuki looks at him with a shock expression on her face.

"Why...?" She asks. "Why can you say that?"

"'Why'? Well, I like the color blue and..." He trails off. "It really fits you really well."

"... No one says that to me when they see this..." She confesses.

"Well now you did. If you don't have a place to stay, you can live with me."

"Eh? But... Am I going to be a nuisance?"

"Not at all. After all I only live here in this house."

Outside of the house

A motorbike gets near the house and the rider—wearing a large coat—with a young girl—wearing two large disks in her green hair and she has green eyes—getting off the bike and the rider takes of his helmet showing a large scar on his face.

"Finally found you." The rider says and the little girl climbs up on his shoulder.

"Let's grab her, Wolx." The girl says.

The Rider, Wolx, walks closer to the house.

Inside of the house

Mizuki hears someone walking closer to the house and she starts to shake. Takeshi notices that she is shaking.

"What's wrong, Mizuki?" Takeshi asks.

"He's... here..." Mizuki mutters.

"Huh?" Takeshi says.

Suddenly, several giant red disk crashes through the house, causing it to collapse.

"This is bad!" He exclaims and he picks her up. "Let's get out of here!"

He takes her outside before the house collapses. Once the house collapse, Takeshi turns around and both him and Mizuki see Wolx holding a giant pico-pico hammer in his hand. Mizuki clutches Takeshi's shirt.

"What do you want?" Takeshi questions.

"Hand over the Edel Raid." He demands.

Takeshi looks at the terrified Mizuki in his arms and puts her down before he gets in front of her.

"What if I refuse?" He asks.

"Then I'll have to take the Edel Raid by force." He replies and he swings the hammer, making the disk to fly toward them. Takeshi grabs Mizuki and jumps away from the disks, but one of the disks manages to scratch his shoulder.

"Ugh!" Takeshi grunts and both of them land on the ground. Mizuki then sees the scratch and widens her eyes.

"Takeshi...!" She calls and Takeshi slowly standing up.

"I'm fine." He reassures. "What about you? Are you not hurt?"

Muzuki slowly nods and he smiles.

"That's good." He says in relief and stands in front of her again.

"Takeshi!" She calls again and grabs his hand, making Takeshi to look at her.

"Mizuki?"

Mizuki closes her eyes and starts to chant.

"The pure water that flows, let thy purify the corrupted soul and cleanse them from their wrongdoing."

A light sphere surrounds Takeshi and a mark appears on his forehead.

'I can hear Mizuki's voice flowing through my head.' Takeshi thought.

"Like the blue gem with the water surface, I will engrave my bond with yours."

In Takeshi's hands, he sees a sword that has gems on the blade and the hilt has blue ribbons on the handle.

"Tch! The target Reacted." Wolx points out.

"What are we going to do, Wolx?" The hammer, little girl, asks.

"Isn't it obvious. We're getting rid of the Pleasure." Wolx then charges at Takeshi.

"Takeshi! Front of you!" Mizuki warns and Takeshi looks up and defends Wolx's attack.

"Can I ask you one thing?" He asks. "What are Edel Raids to you?"

"Tools." Wolx answers bluntly. "What about you and that Edel Raid you're using?"

"… Even though I just met her, Mizuki, she is caring and honest. There's no way I'll use her as a tool!"

"Takeshi..." Mizuki silently calls.

Wolx jumps back and swings the hammer, letting the disks to fly toward him.

"Takeshi." Mizuki calls and Takeshi nods his head.

He then swings Mizuki and a wave of water comes out of the blade, coming toward the disks.

"What!" Wolx exclaims and the little girl looks up.

"Wolx!" She calls. Wolx looks up and sees Takeshi is above him and about to do a downward slash, but stops above his head.

"... What are you doing?" Wolx questions. "Aren't you going to finish me off?"

"If I did, that Edel Raid you're using will get sad." Takeshi bluntly says and Mizuki reverts back to her human form and the little girl also reverts back. Wolx then goes back to his bike with the little girl following him and they get on.

"The next time we meet, I'll finish you." Wolx threaten Takeshi and they dives off.

~Sun down~

Takeshi looks at the remains of his house along will Mizuki.

"How in the world I should fix it?" He asks and Mizuki looks down.

"I'm sorry, Takeshi." Mizuki apologizes and she then notices his shoulder is bleeding. "Your shoulder!"

Takeshi looks at his shoulder that was scratched.

"Oh this? Don't worry about it." He reassures and Mizuki touches the scratch. Once she touches the scratch, her hand starts to glow and heals Takeshi's shoulder. "Wow!" He then realizes why Wolx tries to get Mizuki. "Could it be that person is after...?"

"... My healing ability..." Mizuki finishes. "I'm sorry. It's my fault that you lost your house because of me."

"You don't have to say that." He reassures. "I was planning to travel around the world. If you want, you can come with me."

Mizuki looks at him and smiles. "Okay!"
