A tipical morning in the Hyoudou house. Issei's clock started to ring making both Issei and Ryo,whose room was right next to Issei's, wake up. Issei woke up next to Asia who,luckily was fully dressed, this time but usually he would wake next to the Prez. Issei got out of bed and got dressed without waking Asia up. As he was about to wake Asia up and ask her what happened with the Prez someone knock hard on the door. He slowly opened the door to see the Prez wearing only a black t-shirt with a big "F_CK, all I need is U" that was 2x her size,at first he didn't knew from where did she got it but then the light was turned on in his head,the t-shirt belonged to Ryo. Issei never suspected that Prez knew Ryo so the shock of them going out in their freshmen year still took afect on him. Rias was in a very good mood,she woke up Asia and went downstairs for breakfast.
Ryo came shortly after that. He wasn't wearing a shirt, only a black pair of jeans and his favorite pair of black shoes. He was still half asleep and his hair was a total mess, he took a sit on the chair next to Rias and smiled and Issei could observed the blush in the Prez's cheeks as she looked at his brother. Even Issei had to admit that his brother far surpased him,even with the training from Prez he wasn't even close to his brother's level. Ryo was well builded because of the basketball trainings, he was rather skinny but that only made his muscles hardened up more. But something jumped in his attention, his brother had two tattoos on each of his arms,they were rather simple,only medium black circles, one om his forearm and one a litle higher up just below his shoulder, he wanted to know why Ryo got tattoos but his mother told them to go get ready for school. Issei,Asia and Rias got dressed fast but Ryo couldn't decide on what he should wear. The gave up and took his black V-neck classic shirt with tassels neck warmers that was a litle longer in front,black slim skinny jeans and black leather converse all star and a sleeveless hooded leather jacket and a black simple snapback cap to match the outfit but Ryo had a hard time arranging the cap because of his messy hair.
Issei and Rias started to became inpatient waiting for their friend. "What's taking him so long?! Geez, that idiot..." said Rias as she went after Issei's brother. As she entered Ryo's room she saw the boy cursing in the mirror as he was trying to arrange his cap. She looked surprised at the boy as she blushed furiously, the last night she was too tired to observe all the details that made him look even more amazing. She smiled at his nervous look and got closer to him asking "Need any help?" as the boy jump surprised. "Sorry did I scare you?"
"Nah,I was just surprised that's all. And yeah, I guess I need a litle help,if you don't mind." the boy turned to face her with his face inches away from hers. Ryo was blushing a litle as he looked away avoiding eye contact, he closed his eyes and began to think about something else. His thoughts were interrupted by a quick peck on the lips, Ryo blushed furiously as he opened his eyes to look at Rias who was also blushing as furious as him. "R-Rias...why did you..."
"S-Sorry... I don't know what got into me, I just... I just missed you so much and..." she couldn't finish the phase because she was pushed into the wall and pulled into a long kiss. At first she oppose but she slowly lost herself into the kiss. After some minutes Ryo pulled back and smiled, Riss was still shocked but she was happy that her former boyfriend still had strong feelings for her, she smiled as she gave him another quick peck on the lips before they went to school.
Of course the other students would consider Issei filthy for walking next to the school's top idol, Ryo could even hear some boys cursing his litle brother, but now came his turn to be in the middle of attention. He was ready to hear bad things but instead the girl just stared at him I surprise, some even cursed Rias?! for walking next to, according to them,was a model or something. Ryo laughed as Rias was blushing to the constant girl telling her how lucky she is to have such a handsome boy at her side. As she and Ryo got into their class Rias was took by a group of girls for interrogation and Ryo simply looked for a empty chair to sleep.
Classes went pretty fast for Ryo who wasn't paying attention to the teachers but to Rias all the time, the kiss was repeating in his head, wich made him smirk every time she looked in his direction. The day ended quick and Rias, Issei, togheter with Ryo went to the Occult Club. Ryo was greeted by Akeno who was very surprised to see him there,the others were surprised as well,getting a human into this room was very risky but for some reason Rias didn't seem to care too much, neither did Akeno or Koneko. It was an unusually silence afternoon, all the club did was to simply talk,Rias and Akeno were all over Ryo questioning him about his leaving. Issei sighed, his brother got both Rias and Akeno's attention with a mere show up. The things went like that for some more minutes until Rias's expression changed into a one of concern right before a magic circle of the Gremory clan appeared and her brother showed up with Grayfia.
"How are things going,litle Rias?" said her brother with a smile before seeing Ryo. His smile faded away into a neutral look before he spoke up again "What is this human doing him?"
"Brother,you should have told me that you were visiting! This is, um..." Rias lost her words, how could she explain that Ryo was her boyfriend who hates devils from the bottom of his heart, or that she was a devil? She was afraid that Ryo would make a scene but he,wasn't moved at all,he was calm and not bothered by the sudden appearing.
"Well,this human was a name you know? Nobility doesn't have manners these days or what? And I'm Ryo Hyoudou, Issei's big brother." everyone was surprised at the boys reaction especially Rias, her hand was already shaking a litle but Ryo putted his hand on hers as he stood up and gave her a kiss on the cheek. "Now may I ask what is the purpose of this visit?"
After all of them took a sit Rias's brother explained that a unknown powerfull devil was wandering here because of a sudden energy burst that accumulated here and that for some days he would stay at the Hyoudou's house. Both Rias and Issei jumped on that complaining,the answer was a simple one,Sirzechs told them that he was going to stay whatever they said to keep an eye on Ryo. Ryo smiled as Sirzechs told that but Rias was sad,if her brother is there she couldn't made a move toward Ryo anymore. As Ryo checked his phone he excused himself and leave in a hurry after he gave Rias a kiss on the lips making Sirzechs and Issei angry.
It was already dark when Sirzechs finished all the details about the mission. A strange energy apeared out of nowhere and all when to face the so called devil. Rias and Akeno arrived first at the abandoned building, they entered with caution the empty room. As they looked around Ras suddenly screamed at was she just saw,Ryo was lying on the ground with his left arm cut up, she covered her mouth as she fell on the ground crying. When the others arrived the energy was no longer there,Rias was still in shock over Ryo's dying body, Issei fell on the ground beside Akeno who was also in shock. Sirzechs went next to Rias and pulled out a mutant knight piece "You can save him if you want..." but Rias didn't approved.
"Brother Ryo hates devils! And even if I would his arm can't be healed! "
"His arm will be healed, miss Rias. This young boy has a huge potential of becoming the strongest knight. "
"Grayfia...what are you talking about? " asked Sirzechs
"It took a while for me to observe but the boy looks exactly like Prince Hell, Lucifer's first son. If I am correct this boy could be the strongest devil of all times."
Rias took some time to think,Ryo hated devils but she didn't wanted to loose him,not again. She took a breath and started the ritual to transform Ryo into a devil. An overwhelming energy surrounded Ryo's body as blue flames appeared in the place his arm should be, healing his arm. Rias stared at Ryo's body covered in flames,the energy emitted from them were over even Sirzechs's powers. The flames were off fast as Ryo was recovering from the mortal blow that almost ended his life,his head was hurting like hell and his vision was blurry. Rias rushed to his side helping him up as she explained how was it that he was still alive. At fist the boy was confused but then he stoped Rias when she wanted to apologize for transforming him into a devil.
"Chill out,you didn't transforme me,you just activate the devil blood that's inside my body. Thanks Rias." Rias started crying as he embraced her, she always felt same in his arms but now even if he was a devil that sensation didn't change,it was still as warm and as lovely as she remembered. Taking advantage of the situation Ryo stole a kiss from Rias,making her blush furiously as she asked for an entrance wich he gladly accepted.
"Ahem...Would you mind telling us who you really are,Ryo?" Sirzechs said as he was glaring at the boy. Ryo sighed and took a step away from Rias.
"As Grayfia already said I am Lucifer's first son,the prince of hell. And before you ask anything else my original name is Ryuuzei Lucifer Hell,but I don't use my father's name so just ignore the Lucifer from my name." he said before Rias hit him for lying to her. "Sorry Rias,but if anyone would've found out you would've been in danger... Please forgive me." he continued as he bowed before her.
Rias was surprised but Ryo,no,Ryuuzei was right,if anyone would've found out someone would've come after him,someone stronger than her that would've probably killed her. She hit him in the head again,he got up and smiled right before she kissed him again. The moment didn't last very long because Sirzechs told Ryuu that if he hearts his sister he would die. Rias blushed and yelled at her brother as Grayfia hit him for telling something like that. Ryuu laughed as she embraced Rias again and kiss her.
"I think the fun is just about to begin,righ Prez?" Rias blushed again as her newly knight kissed her neck.
"It would be interesting to live with you and Issei...I'm glad you are alright. But Ryuu,as punishment from now on you will be living with me after all,I have to punish my servants when they lie to me... " said Rias to a confused Ryuuzei,she smiled as well when he realised what she just said and smiled. "Too much for you, Ryuu?"
