Issei's plan.

Huff huff. Two very sweaty ladies panted as they laid on the ground. They were extremely tired and just wanted to get the hell out of there . Is this what they had prescribed to ? He was more demonic than those two could ever hope to be which was quite ironical given their current race.

" Alright this is enough for today . You have done wonderfully for your first times . A bit below average but then again I am comparing you to boys. " Isamu said making both of them get a tick mark in their face.

Isamu had quickly transformed from prince charming to the literal coming of the antichrist. He walked to them and offered them a hand up. They accepted and with great difficulty rose up . Sweat was dripping from them and this made their tracksuits stick to their figure enhancing their beauty.

Rias who was more shameless of the two tried to jump at Isamu to which he just dodged.

" Come on , you just made as suffer this much . The least you could do was carry us upstairs. Isamu just smiled at the two of them.

" Sure I can do that if you go for three more laps "

" Tch nevermind "

" Great , I will see you upstairs for some food. " Isamu walked off living the two of them raging at him .

They had ran for 60 laps each and if you considered it well it was 1 km per lap as warmup , WARMUP!! . After that they were given weights of 50 kgs to which they had to do consistent pushups up to 1000 . They did 2000 sit-ups then finally ended with magic casting until their magic reserves ran dry and they had a lot so it wasn't a beautiful experience.

As much as it seemed too much for the two it really wasn't . They were at soul wandering level . This was like telling an ordinary person to do 30 pushups and situps plus run for 300 metres. Simple right ? Well most people pin today's age can't do it because of their state and this was what Isamu wanted to remove from the two. They literally had the potential to destroy him easily yet they couldn't because they were so weak physically .

Why would Isamu go the whole trouble of helping them ? Simple because he needed a training partner that could give him a challenge. Within two months he will be on their level so the power disparity wouldn't be bad when they start sparring .

The two finally arrived upstairs and a fragrant smell assaulted their senses . They checked to see food extravagantly placed on the table. There was roasted chicken on the middle of the table , some rice on two corners of the table with delicious chicken stew with some few seasonings and vegetables.

" Well come on and dig in " Isamu invited them over. The two rushed in and ate ravenously , elegance be damned . They were hungry as hell .

Isamu gave out a small smile as he saw the two eat quickly and ravenously. However when they felt his gaze they stopped their ravenous eating but Isamu encouraged them.

" I like a girl that can eat well " He said which made them resume their eating .

After the food the two took turns to shower then they proceeded to their rooms to sleep . They were so tired that even their goodnights sounded so weary .

Once the two were gone he proceeded to the basement to continue his crippling meditation . After a few minutes , whispers started to be heard . After some while the whispers grew louder and more depressing . After 6 hours he finally woke up from his meditation The whispers quickly faded to until they were nonexistent .

' No wonder Su Yan lost her mind . That shit is maddening . If one isn't used to killing they will run mad but a serial killer will feel more normal because they are already used to the consistent whispers . Furthermore the technique makes you bloated . A powerful energy will be enough to kill the person but if it is low enough , it doesn't kill you so you can adapt and develop it. ' Isamu thought.

He now understood the absurd requirements . He fell to the ground as he rested his body . Every part of his body and dantian was strained. It seemed tomorrow he won't cultivate but rather exercise his body. This normally would have slowed his growth but he had greatly underestimated this technique . Forget reaching soul wandering realm in 2 months , 2 weeks max was enough .

He headed up to eat his share of the food , took a quick shower before going to sleep . It was already 3:49 am so he heard at max 3 hours of sleep. He hadn't reached the stage where sleep wasn't fully important but three hours for him was like a normal person sleeping for 6 hours so he could function well the next day.

PAH !!

" Ah !! " Isamu suddenly woke up in complete surprise.

He looked up to see Rias in school uniform .

" Wake up sleepy head it's already 7:30 am " She said. Isamu could only frown.

He was hit ! He stared at Rias making her shudder.

" I'm sorry please don't punish me !! " She said. Isamu would definitely make her suffer tonight , should she just elope.

Isamu just stared at her for a full on minute before he made a quick movement holding Rias' hand then pulling her closer. Rias was surprised hoping for the worst . She instinctively closed her eyes awaiting for the pain that was never to come . Instead she felt soft lips hit hers . She opened her eyes as she melted into that kiss .

She positioned herself comfortably as they made out but that had to come to an end as Isamu's phone rang . It was Sona .

He picked it up and Sona seemed mad.

" Isamu we might have started dating but I won't hesitate to punish you if you reach to school late " She warned.

" Fine , I'll be there before 8 am dear " He said.

Rias who snapped back to reality excused herself.

" I'll see you later , I have got club things to do " and with that she disappeared.

Isamu sighed as he prepared himself. His speed was 15 times faster than a normal human being which was quite fast so from getting ready to reaching school took him 8 minutes.

Sona stood there menacingly as she saw the influx of students arrive and from among them Isamu emerged. She looked at her watch and found out he was a minute earlier to being late . She glared at him not saying anything to which he responded by going to her and giving her a kiss to the cheek.

' Revenge is nigh dear Sona '

The students watched as her coold expression dissolved to a cute fluster .

"Wow did Kaichou really blush ?" A male student asked.

" You saw it too huh " Another confirmed.

" It should have been me , not him !! " A perverted student said as she glared daggers at Isamu .

Issei watched from a distance as he gritted his teeth . Isamu was really taking everything he had. He should kill him when he has the chance . But how ?

Rias had strictly warned him not to do anything because he was now dating Sona and if he did , he would be immediately killed. What should he do ? He racked his perverted brain until an idea appeared. That's it !! Make Isamu break up with Sona then he can kill him . And it was pretty simple too .

' Isamu has no idea about the supernatural so if I reveal to him that his girlfriend is a devil , he will definitely break up with her and when he does , I will be there to comfort Sona and secretly kill Isamu . This is practically a foolproof plan . ' He thought sinisterly .

He would strike today and reveal it to him . This would definitely crush him

The day continued as usual but there were two people who were behaving strangely that day.

*** At the ORC ***

Rias groaned as she laid on the couch not wanting to wake up . She felt pain from every part of her body and she wasn't healing any quickly.

" What's wrong buchou ?" Akeno asked ,

" I am in pain Akeno . Your brother is a monster in sheep's clothing " Rias said.

" Ara~ Ara ~ Did he do you and Sona too ?" Akeno asked lustfully.

" Why Sona ?" She asked.

" Haven't you heard ? Sona has been seen walking weirdly and she also told Tsubaki she was paining all over " Akeno responded.

" I see . And the answer to your question is yes. You can always come and experience it for yourself. " Rias said. She intentionally made it ambiguous knowing full well of Akeno's perverted nature .

It was almost foolproof . She would join them unaware of what was really happening .

" Oh I would love too " She said with yearning.
