Seeing Ryou bring the blushing Rei out of the cssroom, he decided to follow them. He knew he shouldn't do that, especially since Rei was already dating him, but the tightness in his chest every time the two of them flirted made him want to sh out and interfere in their sweet talk.

  He also wanted to know the reason why Rei decided to date Ryou and forgot their promise to marry each other when they were kids. He still couldn't accept that Rei chose to date another male instead of himself.

  So, for the above reasons and several others, he followed the couple out of the cssroom and walked casually behind them, so as not to raise suspicion about himself.

  After walking for a moment, he stopped. He felt irritation rising up inside of him as he saw Rei and Ryou flirting in the middle of the school hallway. He watched as Ryou's face slowly got closer to Rei's, like he was going to kiss her. His chest tightened, and he panicked. He was about to interfere when Ryou separated himself from Rei on his own, making him breathe a sigh of relief.

  Seeing Rei hurriedly dragging Ryou away from the crowd, he picked up his pace so as not to be left behind. Looking in the direction they were going, it seemed they were heading to the rooftop. He wondered why they were going to a quiet pce like that.

  He suddenly paled as he realized why they were going to the rooftop. What do couples usually do when they are all alone in a quiet pce? Even he, who didn't have any experience with girls, could imagine what they were going to do.

  He clenched his fist and teeth; he should just leave them alone and be done with it. It only brings him more pain if he knows they really do obscene things together. Just when he was about to turn around, with a painful feeling in his chest, he caught sight of Ryou looking at him.

  He doesn't know whether this is his imagination or not, but to him, it looks like Ryou is looking at him mockingly. He then saw the two flirt with each other, and he can see Rei looking happy to be around Ryou.

  He has never seen Rei this happy with him before, except when they were kids. He looks at Ryou with jealousy, seeing them continue to flirt in the middle of the hallway.

  As he seethes in envy, he saw Ryou looking back at him, and this time with a smirk on his face. He grits his teeth and gres at him in anger.

  "This bastard!!"

  Ryou is definitely provoking him intentionally. As expected, he still can't accept the two of them together. He shouldn't leave the two of them alone, and he will interfere if they are going to do something indecent.

  He decided with determination as he looked at them with narrowed eyes.

  After several moments of following them, they finally reached the stairs, but someone unexpected was blocking their way.

  "Shido-sensei?"

  He tilted his head in confusion and got closer to a random board on the wall near them to hear their conversation while pretending to read the content.

  After listening to their conversation, he furrowed his brow; it seemed Rei's father had trouble with the Shido family. Is that the reason why her grades have been held back? He remembered that Ryou always stood up to Shido-sensei when Rei's grade was low despite her answers being all correct. Did she think that he abandoned her when he did nothing and decided to date Ryou, who stood up for her? His face soured when he realized it was most likely the correct possibility.

  He gnced toward Shido-sensei, who was passing him with a fearful expression while mumbling about getting Ryou to pay back for the humiliation.

  He then turned toward Rei, who was hugging Ryou's arm with a happy smile. He looked at the sight complicatedly and hesitated about whether to follow them or not, but his legs moved on their own, and he followed them toward the rooftop.

  Once he reached the top, he saw the door had been closed, and he had no choice but to lean his body against the door and strain his ear to listen to what they were going to do.

  In the corner of his mind, he thought his actions were a kind of stalking, but he immediately shook that thought off and decided to ignore it.

  Listening to their conversation, he breathed a sigh of relief; it seemed they were just going to talk with each other. But then he heard a strange grunt coming from Ryou, and he had a bad feeling about it.

  After several moments, he kept hearing Ryou making grunts alongside Rei's pyful and teasing voice. The more he heard about it, the more he became convinced that they were doing something obscene.

  He clenched his fist so hard, he thought it would draw blood if he clenched his hand a little stronger. He then punched his hand into the wall in frustration.

  Thud!

  If Ryou were doing something indecent toward Rei, he would have no doubt that he was going to interfere. But based on what he heard, the one who took the initiative was Rei. If he suddenly showed up and disturbed their time together, he had no doubt Rei was going to get mad at him.

  He had no choice but to come back, descending the stairs with a heavy heart. He didn't want to keep hearing their promiscuity and act like a stalker.

  ◇ ◇ ◇

  He looked down at Rei with satisfaction while wiping the saliva from his mouth with his hand. He then smirked at her as she gred at him with a blush on her cheek.

  She is currently lying on a bench in a compromising position, her orange hair all disheveled sexily with sweat stuck to it. The button on the upper side of her uniform is undone, showing her rge breasts wrapped in a pink bra, and her skirt is raised with her leg slightly open, showing him her pink panties with a wet spot on them.

  He offers her his hand with a smile, and Rei takes it while grumbling and sits on the bench weakly. She then tidies up her skirt while buttoning up her uniform. He helps her by patting her hair and straightening the disheveled strands.

  "Pervert."

  He turns toward her face; he can see her lips fttened and her eyes narrowed, looking downward while fixing her uniform. Although her cheeks are still blushing, he smirks teasingly at her.

  "Say that to the one who keeps moaning when I touch her."

  Her cheeks redden, and she gres at him hatefully before turning around in a huff and fixing her uniform again while pouting.

  "Come on, I just do it because you touch my wings weirdly. Can't I enjoy your body in return?"

  He smiled teasingly at her and wrapped his hand around her shoulder. There is another reason besides enjoying her ravishing body, like getting Sin Points, but obviously, he wouldn't tell her about that.

  "D..t.."

  "Huh? What was that? Can you say that again?"

  He tilted his head while looking at her in confusion, hearing her soft voice. It was so quiet that he barely caught it with his enhanced sense.

  Her face reddened, and she fidgeted around while grasping the hem of her skirt nervously. She then turned toward him with a surprising amount of force in her eyes.

  "Date!"

  "Date?"

  He looked at her with surprise, and she nodded her head while blushing.

  "I want a date as compensation. We have not yet done it even once."

  She looked at him with determination, and he smiled widely in happiness. He then hugged her in joy while lovingly kissing her cheek. It's unfortunate that she has not yet allowed him to take her lips, as she wants to do it in a romantic way.

  "Kyaah! W-What are you doing?"

  "I am so happy my cute girlfriend is asking me for a date."

  "C-Cute? E-Enough with fttery, release me!"

  "Yes, yes."

  He happily separated from Rei while enjoying her flustered expression, although he kind of missed the soft sensation on his chest when he hugged her.

  "So, when do you want to do it?"

  Rei took a deep breath to calm herself before she answered his question.

  "How about tomorrow? We have a day off from school; you got nothing else to do, right?"

  "Yeah, I also want to talk to you in detail about me turning into a devil, so it's the perfect time."

  "It’s decided then."

  "Yes."

  We both smiled at each other before raising ourselves up and holding each other's hands in a natural way that he barely recognized the action.

  "Let’s go back."

  "Yes."

  We then walk back toward the css, with Rei happily hugging his right arm, while he has difficulty walking as usual.

  ◇ ◇ ◇

  He walks in the hallway toward the student council room after school is over; he has his duty as a student council member, while Rei stays in the school doing tennis as her club activity.

  He absentmindedly looks to the front, looking at his system, which has 1150 Sin Points. He contemptes for a moment what he is going to do with the points before deciding to dump all of them into his level.

  He clenches his fist and tenses his body; he can feel his body growing stronger. He also notices the demonic power in him becoming thicker; he feels he can easily destroy a house without too much effort if he uses his demonic energy.

  He then looks toward his system and observes his status.

  He nodded his head in satisfaction and closed his system interface while humming happily. Not only has he grown stronger, but he also has a date with Rei tomorrow.

  He imagined what lewd things he was going to do toward Rei tomorrow and turned the corner of the hallway...

  "Kyaah!"

  ... and crashed into a girl.

  Seeing the girl about to fall face-first onto the floor, he instinctively wrapped his hands around her body to prevent her from falling and getting hurt. Both of his hands nded on something soft, but he ignored it as the girl's safety was his priority.

  "Are you alright?"

  He worriedly asked her, but because of their position that made him hug her from the back, he didn't know what face she made.

  "... yes, I am alright, but can you release your hand and your thing away from me, please?"

  The girl gnced back at him in anger with her cheek tinged red. He could see that she had a beautiful face, and she also had a good smell that made him horny. He then looked toward where his hand nded, and as he expected, they were both on the girl's soft, big breasts. His penis then twitched when he felt it stuck between soft things. Looking downward, he could see his hips connected to the girl's firm butt. Seeing that they were in a compromising position, he took one st squeeze of the girl's breasts before he released her.

  "Nngh!"

  [Sin Point: +100]

  The girl immediately got away from him and then turned toward him with a gre, her cheeks flushed while crossing her arms beneath her big breasts, making them more pronounced than before.

  He observes the girl's appearance; she has dark purple hair that reaches her hips, with a white hairband attached to it. Her eyes are red as they look pointedly at him. She has big breasts that he is confident are among the top ten in this school. She has smooth and slender long legs wrapped in bck stockings, and she is a bit taller compared to him.

  Having seen her appearance previously in his past life, he knows the name of this girl, which is...

  "I am Utaha Kasumigaoka, a 3rd-year student. What is your name? I want to know, so you can take responsibility for your actions."

  ... Utaha Kasumigaoka from Saekano.
