You're already that strong, but still not?!

¶{Ding! It was detected that the host has changed the plot in the [Sister New Devil] franchise.}

¶{Successfully changed the plot of [Sister New Devil] by 46% by cutting off protagonist Basara's chance to save Mio, making Mio have a good impression on you, killing Zolgear early, making Zest not interested in becoming Basara's servant, making Mio know the person who had killed her parents died at your hands and her liking for you increased.}

¶{Loli succubus, Maria who has known you saved Mio and killed Zolgear also has a good impression on you. Now she has an idea about you.}

¶{Ding! You triggered a critical reward!}

¶{Congratulations host, your Sharingan has evolved into Samsara Eye.}

"Sharingan? Oh right, I did have one...and now it's evolved into a Rinnegan."

Eiji remembered the Sharingan was an early stage reward he received from Miss System. He very rarely used it because with his current strength, Sharingan was only an accessory to make his eyes look cooler.

But now, after Sharingan evolved into Samsara Eye or can also be called Rinnegan. A pair of eyes with concentric circles covering the eyeballs.

Unlike the Sharingan, the Rinnegan was clearly much better than the Sharingan and the enhancement brought by this pair of eyes was also many times stronger.

Using the system interface as a mirror, Eiji could see that his eyes had indeed turned into Rinnegan. But unlike the ordinary Rinnegan which only had concentric circles, his Rinnegan was somewhat similar to Sasuke Uchiha's. It had 3 tomoe or comma marks present in its two innermost circles but instead of purple, the color of its eyeballs was sky blue.

Damn! Isn't this the Blue Rinnegan?!

In the original work, Eiji remembered that Rinnegan had several types. Blue Rinnegan was one of them, this was the type of Rinnegan that one of the villain characters in the Naruto franchise had!

But his also has a total of 6 tomoe, so it's not right to just call it Blue Rinnegan.

"Whatever it is, just call it Rinnegan as usual." Eiji was too lazy to think about the full name of his Rinnegan, what was important now was that he felt another energy that might be called Chakra inside him which almost equaled his magic, many techniques that Rinnegan could use were also imprinted in his brain. Not only that, the cells, bones, flesh and etc. inside his body were also improving and getting stronger.

Eiji was worried that he would become too white like the people of the Otsutsuki Clan, but fortunately that did not happen to him. Probably because of his Human Saint-Galaxy genes, his Rinnegan which also changed his body constitution did not affect his external appearance. So except for his eyes that changed into Rinnegan, his appearance still remained the same.

It was handsome as ever.

¶{Ahem! Host, please, can you not use the system interface as a mirror?}

"What's wrong?"

¶{I'm annoyed to see it.}

"A very honest answer."

He heard Miss System snort. Okay, he stopped looking in the mirror using his system interface. By the way the Rinnegan of the system could be activated and deactivated at will, so he didn't have to worry about walking around outside with chameleon-like eyes.

Actually, Rinnegan looks cool, but not everyone thinks eyes are cool. Some people would also find the eyes scary. Unless in battle, Eiji certainly wouldn't activate his Rinnegan.

After his eyes returned to a beautiful blue color, Eiji smiled. The reward this time was really good, at least it increased his power by a considerable amount. He was becoming more and more OP now. After he became this strong, besides the relief and comfort of getting stronger, he didn't know where he should use all this power.

Eiji suddenly felt bored, maybe now he could defeat the final boss in his world? He was now confident in his power, but considering the background of his previous world, he also couldn't underestimate the creature he wanted to fight.

The funny thing was, Eiji didn't even know exactly what the final boss in his world was. He only knew that in his previous life people called him the "Honkai God" who created Honkai monsters and his apostles called Herrscher who spread throughout the universe. The Honkai Universe itself is rather complicated, there is an Imaginary Tree that has many bubble worlds that are actually worlds inside.

So the creature he really wanted to fight must also be the creature that created the Imaginary Tree. Eiji slightly clenched his fists and sighed.

He didn't know if he was underestimating his own power or overestimating the final boss in his world. But just in case...

"Not yet. I still need to improve my power further."

"At least until I can kill him in one fell swoop without letting him dodge, be reborn, or anything like that."

"As the final boss, how could he not have a way to save himself in an emergency?"

Miss System who heard this from her office... I mean she felt that her host was too cautious. Her host seemed to be the type of person who would level up to level 1000 first before challenging a level 500 boss just because he didn't want his enemy to have a chance of living. Even if it's just a little, he wants the probability of his victory to be 100% and his enemy's defeat to be 100%.

Isn't that too much?

By the way knowing Mio and Maria's fondness for him increased after knowing he killed Zolgear, Eiji was of course happy, he knew the girls knew this from his inner voice.

"But I seem to be forgetting something. That woman, where is she? Wasn't she also supposed to appear in the previous plot?"

"In the original work, she at least appeared briefly in the school health room when Mio was sent there."

The woman Eiji is referring to is of course one of the heroine of the Basara franchise. In the previous plot, Eiji originally remembered looking for an opportunity to accidentally meet the woman and attract her attention.

But strangely he never saw her. Too bad, for now it's better to sleep.

"Kyaa! Behind you! Behind you!"

"Fool, why don't you run away from there immediately?"

"Run! Hurry up and run!"

"That nun ghost is scarier than a wild demon!"

"Wow... No, how could a nun be such a scary ghost?"

"Nana~ Are you scared?"

"N-No way! It's fake! It's just a movie, how could I be scared?! Wait Momo, don't take my pillow!"

"Ara Ara. Can't we watch something else, Rias?"

"No! I won the bet this time, we agreed to watch a horror movie!"

These girls...

Since earlier Eiji of course knew Rias, Lala, and the others were having fun watching a movie together on the first floor. However, Eiji didn't watch with them and said he would sleep first in his bedroom. He also said that so that he could check his rewards in peace of course. After that, he would just sleep.

However, does he need to sleep? In fact no, for him right now sleeping was optional. Even so, Eiji liked the feeling of sleeping, so he wanted to do it just but would he be able to sleep?

Especially with...

Click.

The door to his bedroom was opened from outside.

"Eiji-sama, are you asleep yet?"

"Not yet. Xenovia, why are you here?"

The person who came to his bedroom at 9pm when the other girls were busy watching movies on the first floor was Xenovia.

The blue-haired girl was wearing short black hotpants that showed off her plump thighs and legs, she was also wearing a white T-shirt that was a bit tight and showed off her nice curves.

"Eiji-sama, let's make a child." Xenovia was very straightforward, she locked the door, removing all her clothes to the floor. Her sexy and athletic naked figure was exposed in front of Eiji's eyes.

Although her breasts are not as big as Rias's or Akeno's, Xenovia has a full and perky C-Cup. Actually that size looked perfect with her slender body that was plump and somewhat muscular.

Eiji who saw this naturally had a wicked fire in his heart, especially when he saw the girl's abdominal muscles that made her waist look good to drive. He knew that even though Xenovia didn't really understand about love, he knew the girl's fondness for him was at that level. The proof was that even though the girl's expression looked blank as usual, Eiji could hear her heart beating fast.

"Giving you a child now is impossible, but it's not impossible for us to practice making one."

At first Xenovia was a little disappointed to hear the first sentence, she thought Eiji was not interested in her because she was less beautiful and tomboyish which made her sad. But after hearing the last sentence, she felt that practicing making children was also good. She was excited and wanted to try it immediately so that she wouldn't lose to Irina who had done it first.

However, she was confused as to what she should do next? The church that raised her once told her that women and men could make children but she was not told the details of how to do it, she only knew the process was called sex.

Looking at Xenovia who was excited but still standing by the bed in confusion, Eiji knew he had to teach the girl the steps from the beginning and he would do so.

The next day.

"Eiji-sama~ Eiji-sama~ Harder~~"

Under the sunlight coming in from the window, Eiji looked at the beauty who continued to moan under him. Blue hair with a hint of green in her bangs was disheveled, her usually blank expression long gone replaced by a prostitute-like expression crazy with pleasure. The girl had actually just passed out a few minutes ago, and now she was calling his name in her sleep.

The bed looked very disheveled, especially with the girl lying on her stomach on it whose body was sweaty, had many bite marks, hickeys, and white liquid that kept flowing out of both her holes.

Last night Eiji fucked Xenovia wildly, just like Irina, the blue-haired girl also had a very flexible body and was easily bent in various positions. He kissed Xenovia's head gently before covering her body and getting out of bed.

By the way besides Xenovia, there were also Rias, Akeno, and Sona who were also lying not far beside the blue-haired girl. Their condition was the same as Xenovia's, not long after he and Xenovia started exercising last night. The three girls also came, Eiji remembered he also had to give the three of them a reward for being his wingman. So last night they did a fivesome.

Just like he did to Xenovia, Eiji also kissed the three and covered them with a blanket.

Because Irina and Xenovia who have completed their missions are basically idle except for practicing their breathing techniques and swordsmanship. Yesterday Eiji had actually asked Sona to put the two girls in school. Sona agreed to it and it was easy for her to directly enroll them into the same school as her.

Irina and Xenovia were placed in class 2D, but because this morning Xenovia was too tired with the other three girls after working out all night. She couldn't go to school today. So Irina was the only transfer student who joined Kuoh Academy today.

Eiji closed his eyes and secretly enjoyed the feeling that every part of his body felt stronger after getting Rinnegan. Precisely he was feeling the chakra rushing inside his body, he wanted to try one of the special techniques or jutsu that only people who have Rinnegan can use.

It was just a random idea that crossed his mind of course, now that he was at school, he wouldn't actually do it because the school would be destroyed and many people in it would die if he did.

"Eiji, what are you thinking about?" Lala who was walking beside him poked his cheek with her finger.

Eiji looked at his first fiancée, the pink-haired girl looking innocent and beautiful as always. Under the sunlight, her pink hair seemed to shine and her smile made the surrounding scenery overshadowed. If it wasn't for the fact that the girl was busy watching a movie with her two younger sisters and Nana seemed to be preventing her, she would have joined the four girls who were exercising in his bedroom last night.

The two of them were walking to class together. Asia and Run were chatting not far from them.

"After school, I thought about asking Lala out on a date."

"Right? A date, Eiji will ask me out after school? Hehe~ I want to! I want to!" Lala hugged one hand happily, her voice was quite loud and the other two girls naturally heard what she said.

Asia, especially Run looked at Lala jealously... They also looked at Eiji as if asking what about them? They were also his women now and none of them had been asked out.

Feeling the gaze of the two, Eiji's smile stiffened, he regretted saying date. It's not that he regretted asking Lala out, it's just that he chose the wrong time and place when saying it. He also certainly didn't mind asking Asia and Run for a date after school, but hey he was only one person, okay? A date is where a man and a woman spend some fun time together.

So to solve this situation...

[Speaking of dating. I know it's not fair, but don't worry, Asia, Run, and even others. Even though I'm just one person, I'll organize a date for each of them later.]

Really?

Asia and Run fell silent as they heard this and nodded as if they understood.

They didn't interrupt his conversation with Lala because they also understood there was no way Eiji could ask each of them out at one time.

Unless they could divide Eiji's body of course.

But that was impossible, right?

Eiji sighed seeing the two girls' jealous expressions subside, but somehow he shuddered. Lala who saw this giggled.

As the four of them almost reached the classroom door, in the opposite direction from them, they were stunned to see someone they hadn't seen in a long time.

Since his appearance was somewhat different, it was a bit difficult to realize that it was him at first, but Run quickly realized that the person standing not far in front of her was her brother!

"R-Ren, is that you? Why are you being like this?!"

"As expected of my sister. You recognized me right away. That's right, it's me, Ren!"

With a height of 200 cm, skin that was now slightly tanned and swollen muscles that looked like a bodybuilder. Even his school uniform looked very tight, Ren folded his muscular arms and smiled while showing his white teeth.

Run's face was pale and her lips trembled at her brother's current appearance. To be honest she was a little scared and disgusted to get too close to Ren who looked like that.

Muscles made a man look handsome and manly, Run also liked it, especially Eiji's muscles which were lean and looked like a Greek statue. But her brother's muscles were different because they were too big and his veins protruded!

Not only him, other students were also walking in the corridor, many of them took a detour as if intimidated by Ren's figure.

Ren laughed, his voice was heavy and masculine that it made people's ears tingle. He looked at Eiji and Lala, seeing the two holding hands.

He narrowed his eyes.

"Lala! You see these muscles? It's me! Now I'm so manly! For your sake, I've undergone extreme training. In two months, every day I did push ups 1000 times, shit ups 1000 times, ran 20 kilometers and climbed up and down Mount Fuji 15 times!"

Crazy!

What kind of training is that?

Is that still training that humans do?!

Hearing what Ren said, many students looked at Ren as if he was crazy, in disbelief, and in awe. But for those who didn't believe it, they were silenced after seeing Ren's exaggerated muscles. Even the protagonist Rito who came early to class, he naturally saw Ren and Eiji who were facing each other.

Rito immediately turned his gaze out the window and muttered, "It's a fine morning, the problems around me fortunately have nothing to do with me."
