The next early morning, the yellow sun in the demon realm slowly rises beyond the horizon into the bright orange sky. Assorted colours of soul flames floating around the realm as heavily breathing sounds are drifting from a mountain.
Viewing from the mountain top, Joichiro is resting on a rock as a small figure slowly appears in his sight. "There she is." He spoke.
Near to his position, Wakumi is running on the steep hills with a straw basket full of heavy stones on her back along with her ankles tied with stones too. After reaching the rock, she puts down the basket and collapses onto the grassland, breathing hard.
"Good job my dear, you managed 10 cycles of running from the start," Joichiro said.
"I... can't take...any...more..." Wakumi whined.
"Bear with it, you will be able to run faster than the wind. Trust me." Joichiro said.
Wakumi nods and continues the training.
Back at the shrine, while Tsurumi is picking some demon herbs, she notices Kongiku is sewing beside the garden platform. Curious, she walks to her and asks.
"Why are you sewing an old kimono robe?" Tsurumi asked.
Being noticed, Kongiku replied. "It's a robe I made for Jorichiro himself after he mastered the demon art."
"That is kind of you, but there is something that bothers me. Why is Master Nishikawa just a soul flame and trapped in his sword?" Tsurumi asked.
With a small sigh, Kongiku explained. "The reason he is trapped is that he abused the Chichi Ki style to fulfil his sexual desire, cursed by the power of the tree and trapped in his sword for a thousand years," she said.
"That's terrible. But I never heard of that demon art style before." Tsurumi replied.
"I would say it is long lost in the demon art scroll, one of the most ancient sexual powers given by the tree of lust. A power to steal female chest's sizes for spiritual power." Kongiku explained.
"Maybe it was banned because of its power," Tsurumi said.
While sewing, Kongiku asked. "Have you brought the herbs I need?" She asked.
"It is almost full in this small basket. But why would you need them?" Tsurumi asked.
"It would be a secret between us," Kongiku said.

In the afternoon, Wakumi is taken to a waterfall wearing a white kimono. Joichiro insists on her to sit under the fall as the iced-cold water pours down on her.
"To strengthen your spiritual energy, you must meditate under the waterfall for the entire day. This will help you to balance your power as you master it." Joichiro said.
While getting wet, Wakumi is chatting cold as this is her first time. She puts her hands on her knees and closes her eyes for a long meditation.
Looking from aside, Joichiro is staring at her as his face is getting excited. "Woah, the water made your body see through your clothes. Still have a nice body shape." He spoke.
But Wakumi can hear him and throw a pebble on his face.
"Would you be quiet?" She shouted.
Joichiro looks back and said, "You should calm your "little rod" first, you have a "pitch tent"."
This makes Wakumi lose her patience, in a second Joichiro gets whacked by a bigger stone and smacked onto a tree trunk.
"I will definitely kill you for that!" Wakumi screamed.
Back at the shrine, Tsurumi is crushing some demon herbs as Kongiku is searching high and low in the living room.
"Kongiku-dono, what are you searching for?" Tsurumi asked.
Just finished, Kongiku let out a gasp. "Oh! Found it!" She spoke.
She comes out from a cupboard with an enormous clay jar with a kanji of "Oni" written on it.
"That's a massive jar." Tsurumi said.
"I thought he had already finished drinking it, glad that there is more in it." Kongiku said.
Curious, Tsurumi gets closer to the jar and smells it. She jumps back with her hand covering her nose. "It's demon flame sake! One of the strongest sakes made in the deepest level of jigoku which only Shuten-doji can drink!" She spoke.
"That's clever of you. With the crushed herbs and mix into it...Fufu, it will become the strongest potion I have ever made." Kongiku said.
Looking from aside, Tsurumi was still puzzled. "I am wondering what she is planning for with the herbs and that smelly sake." She thought.
-^-^-^-
While having supper during night-time, Wakumi is munching hungerly while Kongiku and the others watch.
"She is surely hungry after those training sessions," Tsurumi said.
"She is making progress; I ensure she will be stronger than me." Joichiro said.
As Kongiku hears others chatting, Wakumi hands over her bowl to her. "Onee-sama, another one please," she said.
With a smile, Kongiku takes the bowl and refills it. Joichiro noticed.
"You got a much bigger stomach, I am impressed." Joichiro said.
"She is still just a child, eating a lot is normal for her." Kongiku replied.
After the meal, Wakumi lays down on the mat with satisfaction. Kongiku cleans up as Joichiro floats next to Wakumi.
"You still have some energy, want to train more?" Joichiro asked.
"I think I will pass; the previous sessions have worn me out." Wakumi replied.
"Well keep it up, more to come." Joichiro said.
Then, Kongiku returns with a small white sake bottle in her hand and Wakumi is surprised. "What is that Onee-sama?" She asked.
"It is a special drink I just made only for you." Kongiku replied.
As she puts down the bottle, she reaches her sleeves and takes out a small bottle. Once the lid is opened, a small drop of thick white content is poured into the sake and Kongiku closes the lid. After stirring the sake bottle, she picks up a cup and pour it out.
"Here you go~," Kongiku said.
Looking into the cup, the sake is pure milky white. Although Wakumi is still confused, she holds the cup and gulps in one go. In a second, she coughs hard. "Yech, it tastes strong and bitter," She said.
While looking, Tsurumi moves closer to Kongiku. "Are you sure it will work?" She asked.
"It definitely will, because I tested it on Joichiro back then." Kongiku said.
With those words, Joichiro suddenly sneezes.
-^-^-^-
Days after days, with the continuous harsh training by Joichiro, Wakumi is slowly able to run as fast as a Hayabasu (Peregrine Falcon), skipping through trees to trees.
"I have never run that fast." Wakumi said.
With Joichiro at her side, he is pleased to see the progress she made.
"Always trust yourself, you are a fast learner." He spoke.
After strengthening her stamina, she learns how to use all kinds of weapons, such as katana, tanto, and naginata. Besides learning the weapons' characteristics, method and strategies are taught with imitate level.
"Try to cut those arrows as fast as you can." Joichiro said as he summoned two skeleton archers for practice.
The moment arrows are shot, Wakumi focuses her instinct and slashes all incoming arrows. Now the skeletons are shooting even faster than the speed of light, but this does not stop Wakumi. Joichiro noticed something after she blocked all the attacks.
"It seems you have awakened the Demon Eye of Prediction, a power of sight to predict your opponents' movements. But normal humans can't awaken it unless they possess darkness in their heart." Joichiro said.
"What do you mean?" Wakumi asked.
"I felt a demonic aura around you, but how come? You are not being possessed." Joichiro said.
With a moment, Joichiro's mind flickers. "Unless...you have been taking kitsune potions every day!" He spoke.
Wakumi is getting confused, "Potions? But I didn't drink any unless Onee-sama gave..."
Suddenly, she screams and that makes Joichiro jump up.
"Don't scream like a monkey!" He spoke.
"The sake! Onee-sama gave me every meal!" Wakumi said.
Shaking his head, Joichiro sighed. "I knew it, just like the past what she did to me." He spoke.
While Kongiku and Tsurumi resting under a shrine tree, they admire the setting sun beyond the orange sky.
"I think it is almost time." Kongiku said.
"For what?" Tsurumi asked.
Kongiku does not reply but with a smile on her face, the day Wakumi's training will close to an end.
-^-^-^-
The day Wakumi's training is over, she is called by Kongiku to a special place, a garden where the Tree of Lust stood.
"What are we going to do, Onee-sama?" Wakumi asked.
With Tsurumi and Joichiro's presence, Kongiku turns to Wakumi. "Wakumi dear, it seems you have passed all the trails you faced. Now I will give you a power, which normal humans and demons cannot possess," she said.
Standing behind Kongiku is the tree, colourful fruits with different shapes are hanging on it. As Wakumi looks at them, they look glitter, smooth, and juicy. She tries to reach them, but Kongiku stops her.
"Let me pick one for you." Kongiku said.
While selecting, Kongiku found the right fruit just for Wakumi. It looks like a peach, wrapped in pink and yellow. After picking it down, she holds the fruit in her hand.
"Wakumi, before you can have it, can you answer my last question?" Kongiku asked.
On the other hand, Tsurumi feels a bit anxious. "Why does she need to ask her questions?" She asked Joichiro.
"The fruit on the tree is cursed, if you take one of them you will need to face the cause and responsibility for eternal life." Jocihiro replied.
After hearing the question, Wakumi hesitates but looks firmly in Kongiku's eyes. "I will take it as my responsibility!" She said firmly.
"Good luck with it then," Kongiku said.
Receiving the fruit, Wakumi looks at Joichiro and Tsurumi, nodding their heads. Looking back at the fruit, she gulps and takes the first bite. The moment she bites, white thick sticky solid liquid drools from the fruit and Wakumi's mouth. The fruit emits a strong sweet smell as she gobbles it in hunger.
"EEK! What are those sticky things?!" Tsurumi cried.
"That's a different fruit! Kongiku, don't tell me..." Joichiro is stunned.
The sticky white liquid covers all over Wakumi's face and her body, while licking the remaining juice from her hand, she stuns, trembling.
"What...What is happening to her?" Tsurumi asked.
"The possession has begun." Kongiku replied.
"I have a terrible feeling about this, this is not normally done." Joichiro said.
Suddenly, Wakumi feels her body getting hotter and more sensitive, she drops onto the ground as she cannot bear the heat.
"Ahhh!! My...body...whaaaa!! Feels too...good...ayah!!" She moaned.
Tsurumi tries to help by casting but is stopped by Kongiku.
"My god! She is not just being sensitive, she is evolving!" Joichiro cried.
While looking, they notice Wakumi's body starting to change. Her body and hair start to grow a bit, face is getting thinner a bit as the skin gets smoother.
"Ahh! My chest! My chest!" Wakumi screamed.
With surprise, Wakumi's chest is slowly getting bigger and bigger, so are her hips too. She is getting bigger boobs, as they expand too much, her sarashi torn off and her breasts are bouncing and jiggling in the air.
"Aajah!! It feels so good!!" She cried.
Not so soon, the possession is done. Wakumi is sweating, breathing hard. Tsurumi rushes to her as Joichiro turns to Kongiku.
"Kongiku, did you give her the First Ancient Fruit?" He asked
"I did, and a perfect one for her. With this fruit, her powers will be beyond any demons." Kongiku said.
Just then, Wakumi screams and the rest run to her. The moment Wakumi lifts off under her kimono...she is no longer a boy, but a teenage girl.
