Rias was embarrassed by the way she's acting and thinking to herself if her decision was correct considering she's offering her love to someone who she barely knows besides the time they spend chatting. She decided to see how things goes and accept him as her boyfriend since Ryuu told her that once there's doubt and he neglects her even for a moment then she can leave him. Though, it was near impossible considering the [ Harem Protagonist Luck ] and Ryuu who's too devoted in trying to maintain the equity of each woman.
Equality is false and Equity is better terms to satisfy each of his woman who crave their lovers attention with some prefer to have Tim on there on namely Trese and Justine since their not someone who's into romance while Miia has different sense of time and common sense and can be separated with Ryuu for weeks because of her long lifespan. Regardless, Rias won't regret her decisions in joining him in their harem.
Meanwhile, Lucifer could care less about Ryuu's harem as she's a devil where their concept of romance is near non existence and show affection through intimacy namely having s*x.
"I'll just send you a message once I finish sending the paperworks."
"Thank you, Rias. If you need anything from me just ask since I'm now your boyfriend."
Ryuu gave a head pat as the crimson haired young girl blushed from his warmth pampering never expected that she would actually have a boyfriend who didn't care about her looks nor her background. Though, he doesn't deny it was the first thing that drew her to him but he rarely sees her face and normally just chat which makes her personality more apparent than he looks.
Furthermore, both die hard manga readers and Japan lovers shared common Hobbies and likes. Rias thought about his words since she does want to have date with him to get to know more about each other.
"If it's alright, can we have a date at the cosplay convention a few weeks from now?"
"Oh sure, you want the two to cosplay? That sounds really fun."
It was fortunate that this world had anime and manga that have their own world namely Bleach and Naruto along with rip off dragon balls. Rias hearing his comment was ecstatic since her friends couldn't get into what she likes and couldn't visit such places on cosplay.
"Yeah, we can plan it later but are you alright with that?"
"I would like to!? Maybe you can be my Orihime and I'm your Ichigo."
Ryuu shapeshifted to appear like Ichigo, surprising Rias then blushing seeing how good looking he looks. He even made the clothes and blade when he regained his Shinigami powers. Rias skipped a beat just staring at her new boyfriend and couldn't help but be excited for that date.
After a while, the two parted ways as Lucifer followed him back to their homes, then Ryuu noticed something and quickly pulled themselves into the dimensional room that didn't have anyone inside. He could feel the rapid increase of his power when Yaldabaoth had devoured and fused with the soul of the heavenly dragon acquiring a massive information and boost of power.
"Darling!? Are you alright!?"
Lucifer cried out worried about him despite her prideful outlook being attached to Ryuu more than she admits. She's too arrogant to fully express her emotions towards him but at the end of the day Ryuu has a special person. While she was powerless to watch, Ryuu was busy fixing the memory palace to recognize the skills and ability of each experience and technique.
[ You have reach 100 level ]
[ Soul Devourer skill has awakened into Great Soul Devourer Skill ]
[ God Devourer skill has awakened into Great God Devourer ]
[ Unarmed Fighting technique has awakened into Heavenly Dragon Fighting technique ]
He heard the notification and was delighted by the massive boost finding his [ Daemon Prince ] and [ Greater Daemon ] had reached the power equal to Satan Class while canon fodder is the ultimate class. Though, this is only the baseline and cannot say as an overall capability.
Now his body emanating power unlike before secreting a draconic aura around him and could vaguely feel the deep rivalry over Albion base from his memory while also instinctively feeling extremely aroused turned his attention to Lucifer.
"I never knew you'd be worried about my well being, Luci."
"Worried? Huh! This queen could care less if anything happened to you. I am just ashamed for my slave to die without cooking some pancake for me."
Ryuu chuckled at her tsundere personality but could easily see through the falseness of her words because of his [ Pure Byakugan ]. They decided to spend the time inside the dimensional room for now since they were already there. He made some pancakes for Lucifer who happily ate it. She appears quite adorable eating her meal contrasting her usual prideful persona.
"How about my reward for cooking all of this pancake?"
"We can have sex later once I finish my meal."
He paused for a moment from her reply and didn't expect to suggest such a thing but Ryuu grew more aroused than he liked it to be and vaguely guessed that the effect of Ddraig soul would take time to adjust with his. Lucifer finished her pancake before the two headed to bed in order to have some fun.
Ryuu was more forceful pinning her to the bed before giving a kiss that ravished her tongue that made Lucifer shocked that someone had made her aroused expecting him to be the being dominated. She could help but moan from his touch removing her clothes one body before her breast was bare for him to see.
"You look extremely sexy, Luci."
"F-Flattery can't get you anywhere. Just go ahead and fuck me already."
She was growing hotter every minute due to the lustful and newly added dragonic scent that was too intoxicating for her to handle and she's a demon. Ryuu did as he was told and ravished her breast into his tongues, sucking her breast and receiving a moan from her.
"Hyah~♥️! Fuck~!! Why am…ah~♥️…I getting wet from…ah~♥️ your touch!?"
Lucifer was baffled that her lower region was increasingly wet from their foreplay. She normally play with her slave demons woman to satisfy her but this is completely different. It was growing more addictive than anything else growing ever deprave from his touch.
Ryuu enjoyed her moan more than anything else and decided to remove her pants where he saw Lucifer's soaking panty made him smirked before completely removing her clothes.
"Fuck~!! Ah~♥️!! Yes~ ♥️darling♥️♥️more!! Ah~!"
She moans in delight from his tongue inserting into her pussy grabbing his head in burying it into her. Lucifer didn't even care about her images and just wanted to be touched by even dominating her. Like human girls who crave affectionate s*x, Lucifer more incline in having rough sex.
It took a long time for her to squirt her juice into Ryuu's face, who didn't let a single drop go to waste afterwards took a moment to look at her drooling, having seemingly a heart in her eyes. Ryuu didn't waste any time and placed his dick between her breasts.
"Lick it, slave."
His dominating voice causes her to shiver and listen to her new master as she smell the intoxicating aroma of his dick before moving her tongue at the head of his dick while squeezing them in between her breasts causing Ryuu to grunt at the pleasure of seeing her depravely suck his dick. It was completely out of his character but knew that this was what she wanted based on his [ Pure Byakugan ].
Her wet tongue soaking his dick caused an electrifying pleasure while Lucifer enjoyed how demanding he was doing. Lucifer took his dick into her mouth that she was unable to even fit but tried giving the most out of it. After a while, Ryuu could feel his limits and didn't warn her before shoving his dick into her throat.
Lucifer felt her throat being filled by the warm liquid that she drank trying not to waste a single drop but it was too much for her and removed himself from her to spread her body with his cum. Ryuu looks at her seeing Lucifer's body filled with his semen as she opens her mouth lewd showing his seed. He made the image into her mind to never forget this moment.
"More~ I want more, Master~."
"Then lay on all fours then spread your pussy for me."
She did as told, showing her plump ass to Ryuu before spreading her cheeks showing the soaking pussy. Ryuu smirked guided his cock into at her entrances before shoving it into her without warning"
"Hyaaaaahh~♥️!!"
Hearing her moan was a delight for Ryuu who slowly moved his hips, receiving yet another melody of moans from her. He held her waist fucking her like an animal.
"Ah~! Fuck♥️!! This is so good~♥️♥️!! Ah~!! Faster, master~♥️!!"
Complying to her request and grabbing her arms to thrust even deeper into her womb as Lucifer's mind slowly goes blank from the pleasure she's receiving. The two went at it for a couple of hours with Lucifer squirting her juice several times over. Ryuu slowly reached his limits as he grabbed Lucifer closer while pounding her from behind.
"Hyaaaah~♥️!!"
Lucifer then felt a warm liquid pouring into her womb appearing slightly bloated before Ryuu let her go and fell into the bed and passed out while he slowly removed himself and leaked his semen inside her like a waterfall. He smirked seeing her body twitch and decided to clean himself and let Lucifer rest.
