-Deep underground in a layer-
The serpent demon pace back and forth hands grasped behind his back looking at the ground deep in thought.
"That is impossible how a human could become immortal and why the gods would allow such a thing."
The sounds of bones crushing under the feet filled the cave underground.
"For years I have been searching for immortality even leaving myself all the stuff my reincarnations would need in the future."
The demon stopped in its tracks for an idea had appeared to him making him smirk.
"This is good, I will let the girl become immortal then devouring her I shall also be immortal too and shall become impossible to stop from ruling the world."
"The gods will not be able to stop me not even Susanoo" he laugh hysterically making the wall themselves shiver.
-Kushihinada's house-
The girl sat there under the cherry blossom tree waiting for something, or more like anything for that matter she had dreamed someone telling her to wait there and she did for a while.
At last someone came; a man with three blades on a rod wearing a grey cloak with white hair slicked back.
"You called me" the girl said in a soft tone.
"I came to warn you that there will be demons that will try to find you Susanoo has order me to place an illusion around your field in order to trick the demons from finding you."
The scene changed for they were now inside her house in her room.
He placed a scary looking mask on the wall over her bed and silently prayed to himself.
"This should do it as long as you don't remove the mask you will be fine" and with that he left.
-outside Kushihinada's house or the barrier at least-
The demon could sense her near yet there was nothing but a few cherry blossom trees and a field of tall grass.
"It's an illusion barriers, I bet it was Yama, the fool to think an illusion can stop me" he pulled out a bottle which contained a small fairy inside it.
He held it by the wings threatening to rip them if she didn't cooperate; the fairy agree too.
"You're a dream fairy so all you have to do is enter her dream and have her remove the mask without her knowing."
The fairy nodded and turned to powder; the dust slowly flying into the barrier and disappearing from view.
-inside the barrier-
The fairy dust enters the house circling over the girl sleeping in bed and traveling inside her mind under the eyes.
The girl's eyes slowly opened halfway as though in a trance; getting up she turned to face the mask where she lifted it off the wall letting it drop to the floor.
The barrier disappeared allowing the demon to come inside snatching the girl from her own home and leaving a fake replica of the girl in her place.
After a month of living with the serpent demon her heart became darker and darker, and her new powers became even more powerful.
The gods did not notice anything since they only saw the replacement thinking it was the real thing.
It was the day the demon would devour the girl's immortality and power; he called her in.
Kushihinada came in smiling "Yes master" hands behind back and head tilted to the side a little.
"Come here" he said and being obedient he followed his order "your training has come to an end and now I shall-" he was stopped be her laughter.
She stopped looking up at him smirking "Oh no master my training has not come to an end it has only begun" her hand made its way to his throat lifting him off the ground.
"I no longer need you any longer I can find more powerful creatures than you" she said making him angry.
"You bitch" he said trying to transform but could not while trying to gasp for air.
Her eyes lids closed then shot open along with her mouth; she had no more eyes, tounge or teeth just completely black sucking his soul and power inside like a whirlpool.
His body shrunk into just a skeleton with skin tightening around it; she dropped on the floor letting it make a loud thud.
At the same time Yama appeared shocked not noticing the body.
"Kushihinada are you alright a dream fairy told us what happened Susanoo will never forgive us letting harm come to you" he noticed the body finally.
"That's the serpent demon Yamato no Orochi, he kidnapped you?" he asked looking shocked.
She turned around smiling and about to reply when she saw the blades; her heart beat faster as she looked at it mesmerized wanting his power.
She grabbed a sword nearby and attacked making Yama block it; over and over she attacked and he blocked making him mad.
"What are you doing", and he only replied with "fight me I want your power"; he did slicing her body in half he smirked how easily defeated she was.
He turned around and started walking unaware that the body starting morphing back together (quotes; like the morphing in hellsing).
"What the-" he turned back as was knocked through the wall by Kushihinada.
He slowly got up and disappear leaving to tell the gods the bad news.
