Chastity
It's been some time since the offer was made to Issei to become an angel and he accepted on the condition that Xenovia would be allowed to become one as well, and this was accepted for multiple reasons.
Issei and Xenovia were there to welcome back Irina after she was assigned back to Kuoh and subsequently learned the truth of God's death, something that shocked her greatly. But, she was relieved to be informed that Issei and Xenovia weren't really traitors at all, but they must not mention the whole scandal about their exile, or the exile of Asia Argento.
After the issue with Vali and the old Satan Faction, Issei was in fact made into an angel alongside Irina and Xenovia. However, Issei was given an ultimatum after the fact.
Present
Issei's friends are up to their usual shenanigans and peeping on the girls Kendo team while they change. Motohama found a hole that was missed and he with Matsuda as they are perversely looking at the girls in their bare essentials.
However, Issei walks over to them and asks "What are you both doing here?" his voice sounding unease.
Matsuda looks and says "Oh, Issei, good timing, bro. Motohama found this sweet peephole. We're getting some sweet sights here."
Issei, shockingly, shakes his head and calls "Hey girls, some perverts are peeping on you!"
The girls hear this easily and start scrambling to get their clothes on. Matsuda and Motohama, shocked by Issei's sudden betrayal, try to run away but their former comrade grabs them by the collar while their flail around.
Shocked, Matsuda shouts "Issei, what the hell!? I thought we were buddies!"
Issei looks at the two sternly and replies "Yes, but I can't let peeping go unpunished. It's nothing personal, but I've got to put an end to it."
The two continually try to escape in vain as the girls, now dressed find the three and have their kendo swords ready.
Issei lets the two go and tells the girls "I'm sorry that I spooked you all, but I thought it was the right thing to tell you about what was going on."
The girls are shocked by Issei's apology and the captain asks "Wait, aren't you with them?" while another adds "Yeah, I thought you were just a gross perv like them?"
Issei waves his hand and answers "Oh, goodness no. I wouldn't peep on ladies who were trying to get changed after practicing so hard. It's just not right."
The girls, Matsuda, and Motohama are all so shocked they practically go blank as Issei apologizes again and calmly walks off, but he does mention that the hole will need to be covered. What they didn't pay attention to, is Issei's new accessory. In addition to his Rosary from Asia, he now wears a circlet around his forehead that is adorned with a red gem with an angel wing engraved into it.
Later, when walking home with the girls, Issei talks about the day and mentions "I'm thinking that maybe we should all do some more exorcises in the morning before school. It'll help us get in even better shape."
The girls aren't disagreeing with him, but Irina looks a little troubled. Her new school isn't bad and her time with the two makes it easier, but Issei hasn't been the same since becoming an angel. So she approaches closer and asks "Um, Issei, would like to go out with me to a movie?"
Issei looks at Irina and answers "Sure, and would Xenovia be going with us?"
Irina, nervous, adds "No, it would be a date between just the two of us. We haven't gone out since I came back, so…and I am your girlfriend now."
Issei thinks on it and replies "Sure, I don't mind going on a date with you. But of course, we'll have to be careful."
Xenovia is happy for them since Irina's expression becomes happier since she now has a date with Issei. This time, he's actually asked out by a girl who likes him for real. Oddly enough, Raynare doesn't even come to his mind at all.
Later
Irina and Xenovia share a room together since the former came back and they are getting Irina ready for her date. Irina is wearing nothing but her underwear while trying to pick out an outfit. She's choosing between a nice lacey white one with a pair of bracelets or a nice blue trendy outfit with a second necklace.
Irina asks her friend "So, which one do you think Issei will like more?" as she puts the two dresses to her body.
However, Xenovia reminds her "Irina, I hardly think it matters. You know he can't actually feel anything."
Sadly, Irina looks at the mirror and puts on the trendy blue outfit and decides to work on making herself smell and look nice while reflecting on what Xenovia means.
Not long after Irina returned, she and Issei officially began dating. They were happily going out to restaurants, seeing movies, and just simple things they enjoyed doing by being together. But then, their conversion happened. When Issei was reincarnated as an angel, things were fine for a few days, he got over certain things and was adjusting to his new body.
Until…
It was a date when Issei and Irina had a day off to themselves and were walking together in the park. It was a particularly nice evening when they decided to sit on a bench while reflecting on their whole time away.
Issei sighs and looks at the night sky and says "Man, I can't believe I we're still acting so normal even after changing like this."
Looking at her boyfriend, Irina asks him "But you haven't had any perverted thoughts about other girls have you?" Her face concerned about his thoughts.
Issei shrugs it off "No way. After Griselda torched my stuff, and of course, dating you, Irina; that's made my brain a bit more, controlled."
Curious about that last part, Irina wants to know "So, do think I'm beautiful?"
Issei and Irina's faces get closer as he tells her "Oh, hell yeah, I think you're hot."
They lean in and start making out. Things are fine for the moment, but then, Issei's hand seemingly develops a mind of its own when he puts his hand closer to her chest. Despite his rather sudden touch, Irina doesn't mind because Issei is feeling her up, but his mind is the first to go to places one shouldn't, and his wings, a pair of beautiful white feathered wings that brilliantly radiate light, burst from his back and instantly begin flickering. Irina's eyes widen when seeing this she reaches into her pocket and pulls out a small bottle of perfume she'd been saving, just in case, and sprays Issei in the face.
His wings stop flickering as he nearly falls over and rubs his eyes "Irina, what the hell was that for? I'm sorry I got a little grabby, but I really thought you were cool with it." He states in a little confusion.
Irina sighs a little and now gets a cloth to help Issei wipe his face a little to get his vision back while apologizing "Oh, I'm so sorry. But you were starting to fall, and I couldn't let that happen." She explains to him about falling and how lewd thoughts can trigger it.
Issei understands this, but is shocked by it anyway and he asks "Wait, does this mean…We can't do it?"
Irina blushes and her wings pop out and almost begin flickering when she shouts "Now's not the time for that."
They cool down and go back home awkwardly and without any more couple stuff. This would not be the first problem. Times when he's seen girls wearing minimal clothes, walking in on the girls while they bathe, and all sorts of stuff, and Issei has almost fallen more times than he can count. Each time, Irina has had to do something to snap him out of it and make it so he doesn't fall. Things were not easy during this time.
Then, Issei was brought to Michael about this incidents and he has to talk about the issue.
Michael brings it up by asking "Issei, are you having trouble adjusting to your new life?"
Issei remembers being sprayed in the face with perfume and states "Uh, since I've been assaulted with perfume, yeah, I'd call that trouble. Michael, I can't even think about doing cool and kinky things with own girlfriend."
Thinking on it, Michael should have mentioned it to Issei before becoming an angel and ponders "I think I have solution, Issei. I have been working on things since we started this system."
A little happier, Issei asks "Will I finally be able to have a chance to do naughty things with my girlfriend? If so, I'll do anything."
Michael can't help but feel that he's underestimated Issei's perversion, but he does in fact have a solution for the immediate problem. The two of them meet in heaven, inside of a small room for meetings since Issei occasionally comes here for business reasons. Michael has the circlet in his hand.
He looks at Michael and happily greets "Sup, Lord Michael, you needed to see me?"
Michael looks a little perplexed and answers "Yes, because we need to discuss the issues you've been having lately."
Issei thinks on it for a moment and mentions "Yeah, Irina, mentioned that I've been almost turning into fallen angel a lot lately."
Michael sighs with a little disappointment at himself while saying "Why didn't I say anything before turning you."
Defensive, Issei argues "Hey, I can't help if I got manly urges and love ladies love bags. What's so bad about that?" Thinking on women's breasts again causes Issei's wings to pop out of his back and begin flickering again, so he says "Okay, point taken."
After calming down, Issei's wings stop flickering and Michael sighs some more at this display. After taking a seat, Michael presents Issei with the circlet.
"Issei, I want you to know that the work you've been doing is great, and we're happy to have someone as compassionate as you in our ranks. You as my ace, Irina Shidou as my Jack, and Xenovia Quarta as my Queen, and the three of you work so well together. However, your perversion has made it difficult to maintain your status." Michael explains to Issei with a slight disappointment.
Not liking being chastised for his love of the female body, Issei wants to get to the point "So, you said you had an answer to fix my problem? I'm all ears if that's the case."
Michael points to the circlet since Issei has seemingly ignored and further explains "Issei, if you wear this, then you'll have your problem fixed."
Wondering what it is, but also wanting to know it'll do, Issei questions "What? Will this thing turn me into a chick or something?"
Expecting as much, Michael tells him "No, it'll dull your perverted thoughts and make you more adverse to the idea of nudity, lovemaking, and overall female forms."
Issei, thinking the circlet is evil, just about throws it while proclaiming "Something this evil can't be real!"
Michael gets Issei to calm down by telling him "No, it's just a temporary solution." Issei calms down while Michael pulls out a chart and adds "We need to replenish heaven's numbers. But as you'd imagine, it's difficult with our laws. So, we're working on a way for angels to copulate without falling."
Issei inspects the circlet and wonders about it then he pictures himself and Irina about to get it on which causes his wings to flicker again, but then he puts on the circlet and the image completely disappears from his mind.
In his new mindset, no image appears when he replies to Michael "I don't worry about…those things…because they're not fit for an angel to think of."
Michael questions what he's done, but he does get to this Issei's mind when he explains "What we want isn't that explicitly, but we don't you and Irina to have children."
Now that idea appeals to this neutered Issei and he mentions "I would love to start a family with my wonderful girlfriend, since I've been thinking of proposing to her."
He may not like it, but Michael has to leave Issei like this until a more permanent solution presents itself.
Present
Issei and Irina are fighting a stray devil that's been hunting people around a recently closed restaurant as he slices through the devil's body with his holy sword and Irina obliterates it with a ring of light. They take a moment to catch a breath. They've been hunting these strays as favors to the underworld since the peace treaty between factions. However, after listening for a moment, Issei and Irina hear frustrated crying.
"….Perverted old fart…." The voice angrily says while she whines.
Issei and Irina go to where the voice is coming from and they see a young woman and the two recognize her from before. They met her at a peace conference with the Norse gods, specifically Odin. Her name, if they recall correctly, is Rossweisse.
Issei recognizes her and pulls out a handkerchief and approaches her. "Hey, what are you upset about?" he asks while helping her wipe her face.
Rossweisse stands up with a frustrated look and mentions "I was abandoned by that…one-eyed, no good, perverted old god. He just left me here and didn't bother to tell me anything."
Issei, without even thinking, asks her "Why don't you come with us then? We're with heaven, and maybe we can work something out."
Rossweisse stops crying and blows her nose while asking "What do you mean "work something out"…She recalls his perversion a little since she did see his wings flicker before and asks "Wait, are talking about having my body?" Her posture becoming defensive.
But Issei assures her "No, why would I want that?" But Rossweisse takes this as an insult and nearly slaps Issei at frustration towards his words.
But Irina interferes by telling Rossweisse "What I think he meant was that we've got room in our home, and maybe we can talk to Lord Michael about possibly recruiting you. We do get compensation from heaven for our work here."
Michael does pay the three for their work since they do need money and they tell Issei's parents they do work part-time. But Rossweisse could get a full deal out of it. Indeed, she does. After a few hours, Issei and Irina brought Rossweisse to Michael and we was more than happy to convert Rossweisse since in many ways, Valkyries are similar to angels, so her conversion did make sense and her gift with magic makes the choice too easy.
Michael offers her a full payment worthy of her abilities and as well as access to heaven's medicine supplies as a health coverage plan, of some kind at least. She also learned of Issei's goal of reforming heaven so that exiles like Asia and Xenovia's never happen again.
Also….
Irina , not long after Rossweisse's conversion, is given the special doorknob. This happens after another date where Issei wasn't capable of seeing her beauty. Her dates with Issei felt meaningless to her because he can't see her beauty as a woman rather than a person. The doorknob she places on Issei's room and convinces him to come with her.
Special Room
They enter the room and are instantly in awe over the décor of the room, but what catches Irina's eye is the bed, which she and Issei sit on.
Like their original date after becoming angels, Irina asks "Do you think I'm beautiful?"
Issei takes a moment and answers "Well…I think you're a very beautiful person and I really like you as a friend."
Irina doesn't like that answer, so she takes it upon herself to remove Issei's circlet and then asks "How about now?"
Issei's eyes immediately go down her chest because she's wearing her exorcist outfit with some tears in it, on purpose of course, and then Issei almost drools at seeing her outfit. Irina likes this look on his face and then they resume what they left off on that night when the problem began, only this time, Issei's wings don't flicker.
They eventually find themselves on the bed and then Issei mentions "I don't care what that crappy thing makes me say, I think you're really hot, Irina."
Irina blushes and says "Darling, I hope they can be together even closer than this. But I can only think of one way."
Issei swallows some spit as Irina begins taking off her clothes, and he does the same the same. This point marks their relationship as lovers officially. After their lovemaking, Issei proposes to her, and it doesn't take a second for her to say yes.
The Next Chapter will take place about a year later. It'll be the last chapter of Ivory Dragon.
