"Welcome everyone! How are you?"

As Ryuuto, Rias, Mina, Denki, Kyoka, Hanta and Mashirao finally reached the mansion's main door they all saw Momo, who was barely able to contain her excitement, waiting for them dressed in some casual comfy clothes.

"We're all good, thanks for asking Yaomomo!"

Mina, the always cheerful girl, answered her in place of her classmates with the new nickname she had come up for Momo the day before.

"Then let's not waste time and let's get to study, come in so we can start."

After the group got inside and were brought to a table with some snacks on. While Ryuuto helped the other guys study, Rias asked Momo if they could get to a private room so they could go talk, indulging in her request Momo made Rias follow her and soon enough they reached Momo's room.

"What did you want to talk about Rias-san?"

"Do you remember when we talked about our quirks and I told you mine was similar to Ryuuto's?" Seeing Momo nod Rias continued explaining. "What I didn't tell you is that I come from a different world and that I'm also not a human but a devil."

Rias had also explained her origins to Rumi and Eri, with Rumi not really caring and Eri just being excited about knowing new things, and decided to just be honest with Momo since even if she refused Rias could just modify her memories about their talk.

"We devils have something called peerages, composed by Evil Pieces, just like in chess there's a king, a queen, two bishop, two knights, two rooks and 8 pawns. This pieces allows us to reincarnated humans as devils."

After Momo heard Rias she started to understand what was happening and why Rias wanted to talk with her in private.

"So, you want me to join your 'peerage', right?"

"Yes, your ability to create items could be extremely useful even more with your brilliant mind and your strong observation skills, moreover if you accept this you'll get something we call mana that, with enough hard work, will allow you to use that instead of body fat to create items while also giving you the chance to learn magic, reincarnating as a devil would also strengthen your body."

Listening to Rias' explanation some questions popped up inside Momo's head.

"If I become a devil what will change?"

"Apart from what I already told you, you would have an increased lifespan reaching thousands of years, grow wings based on your raw physical strength and magical power and develop a weakness to anything holy."

"What does joining a peerage mean?"

"It's more or less like joining a squad in my case since apart from listening to my orders during rating games, that are something similar to the tournament in the sports festival, you wouldn't be forced to do anything else."

"And in other cases?"

Hearing Rias, Momo immediately noticed how she was hiding something from her.

"That depends on who the peerage belongs to, in some cases you could be forced to basically become a slave but I swear on my name as Rias Gremory, heiress to the Gremory clan, that I will never do something like that."

"Can I have some time to think about this?"

"Sure, but I need an answer before I leave, I can't really let you know about this if you're not part of my peerage."

Once done with all the questions plaguing her mind Momo started thinking deeply about what she just got to know.

'What should I do?... If I accepted her offer I could get stronger but am I really ready to lose my humanity?... Would it even matter that much? It's not like I'll stop being myself because of this...'

After thinking deeply about this Momo finally reached a conclusion.

'I'll accept your offer Rias-san."

Nodding to her Rias took out a pawn piece and after telling Momo what she needed to do to reincarnate her as a devil, Rias started pushing the pawn piece in Momo's chest. Soon after that two devil wings appeared from Momo's back.

"That's it? It was that fast?... I kind of feel disappointed..."

"Don't worry, soon enough you'll notice the rest of the changes, now let's go back to the others, we've been here for about an hour already."

After saying that Rias and Momo went back to the study group and helped Ryuuto teach the others, unfortunately for them Ryuuto had to go since it was almost time for his date with Ning Er.

"I have to go guys, something important needs my attention, I'll see you tomorrow."

Telling them that Ryuuto left accompanied by a maid and headed towards where him and Ning Er had agreed to meet up.

Arriving there Ryuuto saw how he had about 5 minutes left before the time they had agreed on so he sat on a nearby bench and waited for Ning Er to arrive.

Just as the five minutes were over her saw Ning Er approach him wearing a really cute white dress, a pair of nice shoes and a big straw hat on her head.

"Sorry, did I make you wait? I-I don't look strange with this, right?"

"Don't worry, I just got here and no, you actually look really cute dressed like that."

Hearing Ryuuto compliment her and calling her cute made Ning Er blush, to distract her mind from that she spoke with Ryuuto.

"Th-Thank you. By the way, where are we going?"

"I was thinking of going somewhere we could eat something fresh, what do you think?"

"I'm okay with that."

Hearing her Ryuuto smiled and offered Ning Er his arm. Seeing him doing that she immediately latched onto it while getting even redder in her face but everyone looking at her could clearly see a really big smile.

Reaching a nearby shop Ning Er ordered a parfait with Ryuuto doing the same, after they started eating she saw how, instead of eating, Ryuuto was just looking at her.

"Why are you looking at me like that? Is there something on my face?"

"No, it's just that the smile on your face as you eat is really cute."

Hearing Ryuuto calling her cute once more Ning Er blushed intensely while she muttered in a low voice.

"Baka..."

(A/N She said the B-work...)

After finishing eating and paying for their meal Ryuuto brought Ning Er at the local aquarium, seeing all those kind of different fishes amazed Ning Er since in Glory city fish would just be another type of food.

"Ryuuto look! That fish is looking at me!"

______________________________________________

Meanwhile with the fish.

'Who the fuck is looking at you woman?! I'm looking at nice piece of ass behind you. Mmh, the things I would let him do to me.'

______________________________________________

Back to the date.

While looking at the fishes with Ning Er, Ryuuto suddenly shuddered and had a bad feeling but decided to ignore that.

After looking around some more they left the aquarium and headed towards an arcade where they played with different games and Ryuuto even won a teddy bear for Ning Er in one of those claw cranes.

Unfortunately it was getting late so they had to end the date there, once they had reached their house Ning Er and Ryuuto chatted a little before she went inside and he went to accompany Rias at home from the Yaoyorozu's mansion since she had told him she would be staying there to teach Momo how to use mana.

"I had a lot of fun today, thank you Ryuuto."

"I'm glad you liked it, when you want we can do something like this again."

"I can't wait for that then. I'll go in then and wait for you to come back with Rias and Eri."

As Ryuuto was about to respond he was suddenly kissed on the cheek by Ning Er and before he could say anything she had already retreated inside the house.

"You cheeky girl."

Saying that Ryuuto went to take Eri from his parents' house before going with her towards the Yaoyorozu's mansion to bring Rias home.

"Wow! Onii-chan this house is so big!"

"It truly is Eri-chan."

Soon after Momo and Rias reached them with little Eri still being amazed by the size of the house.

"I'll see you tomorrow Rias-san, Ryuuto-san have a nice evening."

"We'll see you tomorrow Momo, remember to get ready since we'll depart after school."

Saying that Rias, Ryuuto and Eri parted with Momo and headed home.

"So? How did your date with little Ning go, Darling?"

Smiling wryly since he knew Rias would ask about that as soon as possible, Ryuuto answered her.

"It went pretty well, we both had fun and she really enjoyed it. What about you two? Did Momo learn to sense mana?"

"She did, she was also able to almost manipulate it but she was too tired so I'll teach her tomorrow after we arrive in my world."

"Eheh, I'm so happy, tomorrow I'll get to know so many new people!"

After that Ryuuto, Rias and Eri reached their home and found Ning Er waiting for them on the couch.

"Welcome back."

Seeing as none of them were hungry, since Ryuuto and Ning Er ate during their date and Eri and Rias ate outside, they just decided to relax in the living room while watching some TV.

After some time Eri asked Ryuuto to take a bath with her and he, being the caring older brother that he is, accepted her request and went to bathe with her, giving the chance for Rias to talk with Ning Er about her date with Ryuuto.

"Sooo? How did it go Ning Er? I want to know everything!"

"We-Well, after arriving at the meeting place I saw him already there and seeing me in the dress you gave me, he called me cu-cute... After that he did it again while we were eating... Then we went to the aquarium and there were so many fishes there! After the aquarium he brought me to an arcade and there we played all kind of games, like the one where you shoot with fake guns at a screen or one where you have to dance according with some arrows that come up on the screen, Ryuuto even won me a teddy bear! Unfortunately after that we had to go home since it was late but I was able to kiss him... on the cheek..."

"Don't worry Ning Er, you'll have another chance on the next one."

"You're right! Thanks Rias!"

Soon after Ryuuto and Eri finished their bath so they had to end that chat there.

"Come here little Eri! The tickle monster still needs to tickle you!"

"Help Onee-chan! Onii-chan wants to tickle me!"

Right after hearing that both Rias and Ning Er saw a naked Eri run towards them and jump on Rias' lap to avoid Ryuuto, who was running behind her with a towel around his waist with his hair still a little wet.

"Rias Onee-chan, Ning Onee-chan why is your nose bleeding?"

Hearing Eri telling them that both of them wiped their noses before Rias took Eri in her arms and brought Eri to her room to get her clothed in a pajama and put her to sleep while Ryuuto went back in the bathroom to finish drying his hair and then go to sleep.

Needless to say, since Rias still had Ryuuto's figure with his wet hair etched in her mind, neither of them slept much that night.
