Hands are better than sponge

Time passed by.

Paul thinks that after the touki incident, he was being watchful in Rudy's training and started to teach Rudy his primary sword technique, his Sword God style.

Because his son already have sword proficiency through Mihawk and have a Sharingan, though he is using it secretly so Paul won't notice, it didn't take long until Rudy memorize all the technique of the elementary Sword God, Water God and North God style.

Sword God style prioritize in being aggressive and more focus on offensive. Water God Style, however focuses more on counters and defense, observing the opponents when to strike and deal damage effectively. North God style was an out of the box sword style, possibly a combination of the previous two sword styles.

His Taijutsu also improve and he can now recreate all the techniques of Might Guy. For now, he refrain himself of using his inner gates so the incident won't happen again and Paul won't get suspicious of him. Of course, he only opens his first gate since his father was watching like a scarecrow and already misunderstood that he know how to use touki.

Rudy didn't have to practice the four principles of nen, which is the Ten, Zetsu, Ren and Hatsu, since he already grasp it when he can make Rasengan. But he trained himself to the advance techniques, like In, he can now make his presence gone.

He conduct some experiment like when Rudy and his father have a sword sparring, Rudy applied a mana to his wooden sword, another advance technique called Shu, and he combined it with armament haki. Of course, the result is a tie since Rudy doesn't want to defeat his father, but to study his footwork and his attack pattern.

He also tried to combined En, which is to form an invisible dome that surrounds him so he can detect any living beings inside in this dome, and Observation Haki. By doing this, he can now predict any incoming attacks in any directions even if his eyes closed. If only his father isn't watching he will also try to use his Sharingan so his perception will improve further.

He also pays attention to his footwork, so he trained his Shunpo until he can replicate Ichigo's afterimage called Utsusemi and Byakuya's favorite Shunpo technique which is Senka, due to his speed, he can move to his opponent's back and do some critical strikes. He also replicate Z-shake and Vanishing step of Ye Qiu from the King's Avatar web novel.

The only thing that he can't accomplish as of now is to unlock his Zanpakuto and Cursed Chains. Maybe he isn't ready yet so Senbonzakura refuse to show itself, only time will tell. As for the Cursed Chains, he didn't have time to bite, take a bath or sleep with chains since every night, Roxy and Rudy are sleeping together ever since.

As for taking a bath with chains, he can't also do that.

Inside the bathroom, Rudy was sitting in a small chair while Roxy was rinsing his hair full of shampoo.

"I didn't think that you can apply magic in that way. Teaching you magic gives me some benefits, since I can see some pointers on how you tackle the very essence of magic." Roxy praised his student when she saw that Rudy can now do Iron magic by combining Lightning and Earth elements.

Every time Rudy was done in magic lessons, he convinced Roxy to take a bath with him so they can relax and make there bodies cool off. Of course, Roxy was a little bit hesitant at first because she can feel that even though his student is still a kid, his feelings for her are genuine.

But because he is persistent, Roxy gave in and tell herself that nothing bad will happen since it's normal to take a bath with a kid.

Rudy, of course, was glad because even though it's shameful to use his underage body as an excuse, he's got an opportunity to take a bath with Roxy through his own effort, without using his illusions. Even if he want to, he can't. Since he still not practicing his illusions.

After Roxy was done in rinsing Rudy's entire body, they exchange position and Roxy was now sitting in the small chair. Rudy get some soap and rub it in his hands while applying a little bit of water then start to clean Roxy's back.

Although Roxy agreed in taking a bath with Rudy from now on, she can't help but to feel embarrass every time Rudy touch his fair skin. He said to her that using hands is more effective than using a sponge, so his small but rough hands are directly touching her body.

"But Teacher Roxy, I can't help but feel proud when you can now also use voiceless incantation." While Rudy was now washing her shoulders, he diverts her attention so she won't get agitated.

"No no Rudy, because you gave me some pointers, I can now do the voiceless incantation for only elementary magic. I still can't do it for intermediate magic. Now I feel ashamed as your tutor." Rudy was now cleaning her chest thoroughly when she tells him her worries.

"Just think about this, now you have a chance to improve and use voiceless incantation for intermediate." Roxy can't help but to give him a smile since she appreciates his word of encouragement.

"But for now, I found some weakness in voiceless incantation when a normal magician use it." Rudy listen carefully while cleaning his tutor's tummy.

"When doing magic with chants, since it was properly invoke, the appropriate mana was used and produce an acceptable result of attack magic, but when I use voiceless incantation, though it was still elementary magic, the mana usage was somehow lessened, producing a weak attack magic." Roxy explains to her student that since she was now an adult, she can't fully grasp the imagining stage causing her to use less mana and producing weak magic.

"Hmmm... But if my theory is correct, where if a child practice magic in early stage, they can do voiceless incantation with splendid results." Rudy cleans her lower part without a malicious intent. He doesn't want to make Roxy disappoint and feel disgusted to him, he can't throw now his hard earned opportunity to take a bath with her.

Because Rudy is behind her, he can't see that Roxy was blushing right now. Her mind was in chaos right now, but eventually, she accepted her student's hands since he's cleaning her only, nothing else.

Every time Rudy was cleaning his home tutor's lower part, he can feel a slight wetness and stickiness. Using his will of fire, he now proceeds to clean her thighs until he manage to clean her legs and toes.

The two was now silent and didn't want to break the awkwardness. Rudy, still feeling aroused... I mean, feeling embarrassed, now washed Roxy's hair.

"By the way, remember when I asked you a question before I teach you on how to combine two elements?" Roxy already calmed her heart and mind and try to break the awkwardness.

"Of course I still remember, you said two elements and I have to tell you the result when those two combined." Rudy listens attentively to his tutor because he found her lessons very interesting. And he find her cute when he always saw his serious face.

"I still couldn't believe that your answer is wood when I asked the result of water and earth. As far as I know, it's mud, but you showed me and you literally made a tree out of thin air. I tried to do your wood magic, but I can only produce mud. Now I'm intrigue." Before he answer her inquiry, he begins to rinse her body slowly while applying a slight heat in the water using his fire magic.

Roxy didn't expect to feel warm while rinsing, that's why her whole body quivered.

Now the two was done cleaning there body, Roxy stands up and went to the bathtub. Since they always do this, Roxy calls her student to join her in the bathtub.

Since Rudy's physique is small, Roxy let him to lean on her body and she hug him in the process.

"What? Didn't expect of being hugged?" Roxy said this softly in his ears, causing him to feel shy.

Rudy clears his throat and said. "Maybe because we have different understand about water and earth, that's why we have a different result." Roxy giggles when she can see her student trying to hide his embarrassment.

Rudy, being hugged by Roxy, stayed in the tub for a while. They can feel each other's warmth and trying to tell themselves that this kind of situation is normal. Taking a bath with an older sister/little brother is normal.

While the student and teacher are having a moment in the bathroom, Rudy's parents are having a conversation in the living room.

"See, I told you. Rudy has feelings for Roxy. I'm proud of my son." Paul smirks to his wife while feeling envious for his son's talent in handling women.

Paul admits that he was a playboy when he was young, he even take Lilia's virginity when they were students in sword dojo. He also has an illicit relationship in his female members when he was still an active adventurer. Of course, he stop it when Paul married Zenith. Or so you thought.

"And that's the worst trait that he can get to you, darling. I don't want our son to become a womanizer and play women's frail heart. I swear that I will teach him to be responsible and sincere when it comes to us, women." Zenith glared at his husband, warned him that if there son, Rudy, makes women cry, she will blame him for the rest of there lives.

Zenith really loves Paul because she can see that he was sincere in there relationship. Although she knows that Paul are conducting an illicit relationship with Elinalise and Ghyslaine before, her friends and also a member of there party.

"Speaking of our son, his talent is somehow abnormal, he isn't five years old yet and he already learned all of my elementary sword techniques." Paul couldn't believe that this child was a prodigy in swords, and now you tell him that he was also proficient in magic? Thinking this, he tells to Zenith his anxiousness.

"See I told you, remember when I tell you that I can somehow detect maturity in his eyes? But I still see some childishness in his actions. Like he always request sweets before having a dinner or the like." Zenith said this while still pondering in there hunch.

"But having a talent or not, Rudy is still our child. No matter what happens, I'm going to shower my love that he deserves." With eyes full of determination and love, Zenith also encourage his husband that we should accept him no matter what he is.

Seeing his wife like this, Paul couldn't help but to approach his wife's face and peck her lips. Zenith accepts her husband's approach and let him lead the way.
