"That offer of reincarnating you is still good whenever you want it Issei-kun. I don't want to pressure you but you seem to be getting worse faster and I hate seeing you like this." Sona said looking concerned as she helped wipe the blood off of Issei's chin when he had an attack while playing a game of chess with her. It had been a year since Sona had first offered him reincarnation and she was still unsure what to do with the knowledge of Grafiya-sama possibly having a child with someone outside of her husband Sirchez…Rias's older brother.

"I know Sona-chan but my answer is still the same. I'm not sure if this will stay with me when I become reincarnated and it's rather…painful during some attacks. I don't want to be like this for hundreds of years…" Issei said smiling weakly at his best friend and the Student Council President. Over the past year the two had become near inseparable, many mistaking them for a couple and while neither would mind the thought of dating officially…Issei didn't want to saddle her with dating a dying boy and Sona didn't want to try and date him while keeping his possible parentage a secret along with their engagement.

"I understand but please. If you die by something other than this illness…please promise that I can reincarnate you. I don't want anything to happen to you but it's better to be prepared." Sona asked gently looking at him with soft violet colored eyes.

"If I die by something other than my illness…I give you permission to resurrect me as one of your pieces." Issei finally conceded to that much, and besides she did admit there was a chance that being turned into a devil and getting a body more suited to the powers might actually help him heal from his illness.

Not only would a fully devil body help regulate his powers, but his connection to her and her water magic would help tone down his fire based powers and bolster his ice ones. That meant that the fight inside of his body for which power was dominant would end and his body would, hopefully, stop tearing itself apart.

Of course thanks to his kind nature, fondness for roses especially those made of Ice, and his refusal to date anyone most of the girls started calling him the Frozen Rose Prince. Yeah…he was as sought after as Kiba 'White Prince' Yuuto, Rias's Knight who had a habit of sneering down on Issei's when his sickly side came closer to the surface.

"Thank you Issei…you…you're important to me and…I don't want to imagine a world where you're taken away from me by something you didn't plan for. Your sickness…I can understand…anything else…I refuse to believe it." Sona said smiling relieved at him and making him blush a bit. He had been startled to realize that he had a massive crush on Sona since around the sixth month of last year…but if the comments Tsubaki and Momo sometimes would drop…his feelings were returned.

They were, Sona just didn't know how to tell him. She didn't want to seem as if she were pressuring him to date her or become a devil for her. That was Rias's job.

Speaking of the red head she seemed to have some kind of grudge or something against Issei, spreading malicious rumors to the rest of the school. The Kendo girls and Student Council didn't believe a single one…the rest of the school…well…Sona decked one boy who caused Issei to cough up blood when he had punched the spikey brown haired boy for 'forcing Sona-Senpai to spend time with him'…the boy's jaw had been broken in two places and Tsubaki had to quickly cover for her King's enhanced strength by mentioning that her overprotective big sister had insisted Sona learn martial arts before attending public school.

Not like it was a lie. Serafall was notoriously overprotective of her baby sister and made sure she knew three ways of defending herself with just her hands and feet before she turned ten in Devil years, around one human year. Sona was also acutely aware of her Sister's Knight, Peko Pekoyama, who was Sona's self-proclaimed Guardian constantly checking in on her from the shadows even while she was at school.

"I'm just sorry that I keep hurting you and everyone else because of this illness. I made a fallen Angel disguised as a young woman from another school cry yesterday by accident when she asked me out and I informed her that I wasn't interested in dating at the moment due to personal reasons." Issei said laying his head on Sona's shoulder when she sat next to him, their game abandoned as they just relaxed and enjoyed each-others presence.

"Is it wrong that I'm glad you told her no the same way you've told the human girls no?" Sona asked tensing a bit at the mention of the Fallen Angel after her fiancée but relaxing at the familiar and welcome warm and cold feeling against her side. He was like a giant heat/ice pack that soothed away all her aches and pains and he wasn't even aware of it most of the time!

"You should know that I don't treat people different just because of what they are. Take away the powers, longer life spans, and wings…all you have left are humans. We all still bleed the same color." Issei said tiredly while Sona smiled and moved so that he was resting his head in her lap.

"Take a quick nap Ise-kun. I'll wake you in time for you next class." Sona said carding her fingers through his hair as he looked up at her surprised but then relaxed.

"Thanks." Issei said smiling slightly and blushing a bit as he turned and nuzzled his face into her stomach, curling up around her on the couch. She blushed a bit as his arms wound around her easily, holding her in place unless she wished to use her enhanced strength against him, which she would never do.

"Anytime." Sona said smiling slightly down at him as she relaxed and kept carding her fingers through his hair. Within two minutes Issei relaxed and his breathing evened out to show that he was asleep and Sona looked up and at one of the shadows.

"Hello Peko-nee. Nice to see you again even though this is fourth time you've checked on me this week…and it's only Tuesday." Sona said smiling as an apparent twenty year old woman with white hair and red eyes behind glasses wearing all black stepped out of the shadow, a shinai hanging at her side and a sheathed sword on her back.

"I've always sensed strong ice magic and a strong fire based sacred gear since coming to check on you last year. You were often around the source but I was unable to pinpoint who exactly it was. I was concerned that they would harm you." Peko said smiling slightly at her charge. She had declared herself as Sona's protector the moment she first saw the girl as a newborn babe…and Serafall openly encouraged the Strongest Knight in the Underworld's desire to protect Sona from any and every threat. Of course growing up around Peko and her sisters faction, who were just as protective of her as her sister was, that led to the rather amusing if not looked down upon by the older devils, habit of her calling them 'nee' or 'oni' instead of just their name.

"Ise-kun won't hurt me. Even when he rejected my offer to reincarnate him last year, despite the fact that it will help with his illness, we remained friends. In fact he's one of the best friends I have. The others will agree with me, we're all rather protective of him." Sona said smiling down at the boy and carding her fingers through his hair without thought.

"So I've noticed. He feels…similar to Grafiya-sama." Peko said staring at the boy with his head on her princess's lap.

"He's at least a partial devil. He…also looks similar to her at times. He has her smile. I remember it from when Rias-san and I were children. Whenever he's working on something such as his artwork he has a neutral face on that's almost exactly like hers. His face has a similar shape to hers and he has her habit of trying to maintain a distance with everyone, although that might be because of his illness." Sona listed the similarities that popped into her head from what she had noticed when idly observing the boy.

"So it's possible that he's Grafiya-sama's secret child." Peko said making Sona sigh slightly as she finally gave up on trying to find a subtle way to learn about the possible parentage of her best friend, her crush, her fiancée.

"Peko-nee can you do me a quick favor and ask that Grafiya-sama come here for an important matter real quick? If she asks then can you just mention that I've found a student with strong Ice magic that is tearing his body apart?" Sona asked looking at her swordswoman of a 'sister' who looked at her for a moment then nodded.

"Of course. And if she presses for more like why this boy is so important to you or why she particularly is needed?" Peko asked getting ready to leave for the Gremory mansion.

"Then tell the truth or at least a partial. No need to tell her about our thoughts that he might be a relative of hers. Unlike me or my sister he has little to no Water Magic. All Ice and Onee-chan's Ice magic is an advanced form of water while Grafiya-sama's element is naturally Ice with minimum water." Sona said making Peko nod, that made sense. Serafall learned how to use Ice by training her Water magic relentlessly. Grafiya however had Ice as her natural element and only had a minimum amount of Water magic because of it.

"And why he's so important to you?" Peko asked stepping into the shadow to hide her magic circle which was all black, showing her command of shadows.

Peko was already halfway through the circle when Sona answered. The answer caused Peko to stumble in shock, which had the effect of her stumbling into the circle and falling on her ass at the Gremory manor.

"He beat me at chess."
