The students were blushing from the charming words of Ryuu that normally cause a massive scandal considering he's a teacher and she's a student. Fortunately, logic doesn't exist in an anime world and only causes the woman to feel jealous towards Aika while wooing them.
Meanwhile, the perverted girl slightly blushed and was taken aback by the reply while smugly smiled. Ryuu was the same amused that this young girl was bold and perverted. In the past, he wasn't a lustful person but eventually grew a pair when it came to women.
"You may sit down, Miss Kiryuu. Anyone else want to ask Kizuno-sensei?"
One by one the students asked numerous questions, namely about his relationship but he vaguely answered all of them. Afterwards, he began his lesson with the students where Aika tried her best to be intimate with him which he happily enjoyed. Aika was an entertaining young girl despite how she looks and is actually quite the listener.
Few hours later, his class was over and headed his way to Occult Research club walking his way to a forested area of Kuoh where he arrived to see Rias at the window with her hair dancing along the wind while she smiled upon seeing him arrive and gave a wave.
"Who are you waving at, Buchou?"
Ryuu saw a black haired woman looking out the window and saw him taking a few seconds before her eyes glinted in suspicion looking at her king who seemed to blushed. She was curious about the handsome young man that was coming to their club without anyone inviting him. Akeno felt a strange enticing air that made her drawn to more. Rias saw her best stop blushing and frown afraid that she might join his harem.
Though, she doesn't stop him from getting more since he already had harem before she had joined but having her best friend could prove troublesome. Regardless, Akeno would eventually come around and join them in their fun.
"Should I prefer tea for our coming guests?"
"....Yes, that would be delightful, Akeno."
"Yeah that would be kind of you. Thank you."
The two heard him then turned to see him inside sitting at the couch much to their surprise. Ryuu was sitting on the sofa with his legs crossed grinning at them after seeing their dumbfounded faces. He simply used his [ Divine Hivemind magic ] that contains space attribute magic to teleport himself to a place he can see near instantly but take quite a toll.
"Ara~ That's quite an entrance I must say."
"It isn't a big deal. Let me introduce myself, I am Ryuu Kizuno at your service and Rias Boyfriend."
Akeno heard his last words and grew even more curious looking at her friend while giving dangerous intentions and licking her lips. Rias sighed at the bluntness of Ryuu even though it had only been a few days since they'd become a couple and had few dates. Her queen had been ever growing suspicious about Rias since she started to smile more than before and now understood the reason. However, she's quite worried about the situation with the Raiser.
"Rias never said that she had a boyfriend, it's nice to meet you. I'm Akeno Himejima, I hope we get to KNOW each other~"
Akeno moved his way towards him, having a seductive and alluring tone that any man could easily be enticed by her voice alone but Ryuu was indifferent and smirked, knowing what she was implying. Rias frowns at how her queen is trying to get intimate with him.
"*Ahem* Akeno, can you do that later and prepare some tea?"
"Ara~ someone jealous that I might steal your boyfriend?"
"Stop the teasing. I'll introduce all of you to Ryuu later. I believe Koneko and Kiba had just finished their class by now."
Her queen only smiled, prepared some tea for them and gave a cup of tea to Ryuu who took it with grace as Akeno sat at his side pressing her chest trying to see if he would react yet remain still drinking the tea. Though, it was extremely aroused as her breast was completely different from his other lover. Rias noticed what she was doing and quickly took his other side.
"What do you think you're doing, Akeno?"
"Ara~ Ara~ no need to be jealous, it's not like I'm going to steal him from you. I am just curious how he managed to become your boyfriend and I seem to understand."
Akeno was too proactive and loved teasing similar to Kanae but she is too much to handle and she saw his tent with bulge making lick her tongue while Rias frowned and pulled Ryuu towards her chest.
"Don't think I'll let you do as you please!"
Ryuu wryly smiled at the two bickering, pondering why Akeno seems to act rather quickly when approaching him then recalled how she's someone who enjoys teasing. He didn't mind the attention and he just took a sip of his tea then recalled that he had biscuits and took out some plastic bags placing them on the table.
"Oh right, I baked this. Hope you two like it."
They halted their fights and turned to see the biscuits that Ryuu took out. Rias was curious how it tasted after knowing that he was a phenomenal chef. She had already met his harem and got along pretty well with everyone. Akeno and Rias took a piece before their tongue was assaulted by flavor and moaned in delight.
"So how was it?"
"It's unbelievable delicious~"
"Never tasted this delicious before."
Akeno and Rias enjoyed the biscuits Ryuu smiled before they enjoyed a small chat getting to know more about each other before a knock on the door could be heard as two people came inside. One was a light blonde-haired young man and white-haired Petite young girl.
"Oh I didn't know we had a guest?"
"Hello there I'm Ryuu Kizuno and Rias's boyfriend."
"I'm Yuuto Kiba and I'm surprised our Buchou had a boyfriend."
Kiba was surprised yet vaguely knew that their master had been hiding something, often smiling and staring at her phone and even dozing off while smiling about something. He didn't mind and felt somewhat happy that her master found someone but was worried about the well-being of this person, thinking he was a normal person.
"Hey before you get any ideas, I know all about the supernatural and your Devils."
He was like an opened book with his eyes capable of peering through anything even the thoughts and feelings of someone. Though, it isn't a telepathic link rather just vague guesses that he eventually got a hang of it. After hearing his words, Kiba was slightly surprised how easily he was seen through but thought it was fluke. Meanwhile, Ryuu noticed how Koneko was looking at him curiously as he gave a nice smile then gave her a pat on the head.
"Hi there, care to tell me your name?"
"...Koneko Toujou."
"It's nice to meet you, Koneko-chan. Oh, do you like some sweets?".
Her interest was piqued when Ryuu took another bag of biscuits, handing them to Koneko who reluctantly took the sweets looking at him for a brief moment before taking a bite and made a weird noise upon tasting its flavor.
"Hahaha I guess you do. Wait, slow down, no one is going to steal your sweet and I can always bake more."
He chuckled still patting her head much to everyone's surprise seeing Koneko interact with him despite just meeting him. Ryuu pity her tragic life with Kuroka who is forced to pretend to be the villain in order to protect her considering if she had brought Koneko with her or told her that why she did it then Koneko would likely refuse to leave her and the two would always be on the run.
Ryuu planned to annihilate the Naberius clan if he had the chance or give the opportunity to Kuroka. He could care less about devil society since they're nothing more than hypocrites.
"Now that everyone is here, we've been called regarding a stray devil."
"Can I join you, guys?"
"Not to su-"
"Don't worry Kiba, He's well capable of a fighter and the reason why I invited Ryuu with us to train us a few days from now."
They have been training that they have neglected their jobs as devils, which is why everyone is compensating by doing it now and will train a few days from now. Kiba was reluctant but trusted his Master's words as they headed their way to kill the stray devil.
