I first published this back in 2015 and am now coming back to it. I'm a little rough so please forgive me. I hope you guys enjoy!

I don't own Yu Yu Hakusho obviously.

Koenma's brows were furrowed deep in thought, the contents of a case file spread out across his mahogany desk, their shuffling occasionally interrupted the silence every now and then the Spirit Ruler wore his Mafuuken a little too hard, causing his assistant George, one of the many ogres that seemed to slave away there, to grow nervous and rethink his decision of bringing the file to his boss's attention. After a few minutes the prince sighs and pinches the bridge of his nose; the contents of the file was causing him a headache-how could he have missed something so critical? Reaching over he presses the intercom button, already a half-assed plan formulated in his mind, already feeling the spankings he sure his father would grace him with if he were to discover his blunder. He suppressed a shudder.

"Boton."

"Yes sir?" Came the Grim Reaper's cheery voice.

"I need you to come to my office immediately, there is a matter I need to discuss with you before you head off to Genkai's"

"Right away sir" she chirps.

With that Koenma sinks into his plush chair. Multiple scenarios of a sword and a Black Dragon ending his life plays in his mind's eye. He groans.

"Koenma sir?"

"What Ogre?"

"Is it really all that bad?" the blue ogre glances at some of documents, one of them contains a profile of a young girl. He picks it up as Koenma sighs, "I'm afraid so George; she thinks he and Yukina were the ones who killed her mother," he rests his chin atop his folded hands.

"I understand sir, but how does this affect the twins?" Koenma looks at his assistant, "If Hiei wants to save any possible chance at having a relationship with his sister, he is going to have to tell her the truth. If he doesn't, Yukina will mostly likely find out in the worst way."

"And if he doesn't"

"...Let's just hope we won't have to worry about that."

It was a moment of rarity, it was quiet, save for the natural sounds of the surrounding forest and a Shishi-odosh. Just how Genkai liked it. Content, she sips at her green tea, taking a few meditative breaths here and there. Sure, she had grown fond of Yusuke and the others, she saw them as her grandchildren. Troublesome, loud, dim witted, courageous, and loyal grandchildren, but she was also fond of her peace and quiet. "Would you like some more tea, Master Genkai?" The old physic looks up to see Yukina, a soft smile on her lips. Genkai nods. With a smile the ice apparition takes the tea cup and heads inside. Genkai loved and appreciated the gentle demon, but couldn't fathom what the girl loved about being stuck at a temple in the middle of nowhere with an 'old-hag' instead of with the others. As she thought about this, she couldn't help but think that everyone was overdue for a visit. She smirked, she was getting soft. "Here you go Genkai" She gratefully takes her refilled tea-cup as Yukina sits nearby. The two sat in comfortable silence when it's broken by a yell, "HEY GRANDMA WHERE YOU AT?!" Genkai sighed, maybe the visit could have stayed overdue for a little longer.

The Grim Reaper blinks, despite the documents in her hands, it was hard to fathom that they had completely overlooked the fact that Hiei had a younger half sister besides Yukina. Not just that, the poor dear had suffered a similar painful childhood, growing up believing in the lie that her older brother himself murdered her mother. Boton peers over at Koenma, "Sir, I don't understand-"

"It doesn't matter how this slipped passed as, what matters now is getting a hold of Yusuke and the others."

"Sir!" With a firm nod, she makes her way to Genkai's temple, getting the gang together wouldn't be a problem itself, as they were all gathering for an overdue picnic,however the ferry girl shudders, knowing full well a certain brunette wouldn't be all too happy.

"Oh, Boton, great timing, help me take these out will you?" Without waiting for a reply Keiko hands over a few trays of finger food over to the bluenette. An array of mixed and matching throw blankets and pillows covered a decent sized area, with two tables pushed together to the side already set up with some food and beverages. Boton nibbled at her lip, what would be the best way to even approach the subject? Kurama caught her eye as she neared the table, thank God for having someone so perceptive in the group, silently she signaled to him to invite an excuse for them to slip away. Excusing himself from mediating the argument between Kuwabara and Yusuke about the proper way to grill the meats, he swiftly makes his way over to the Reaper. "Sorry Keiko, I'm afraid I have to take Boton away for a moment." "Oh Kurama! I totally forgot about the Ogres' union draft! Silly me! No wonder Koenma was in a foul mood!"

"Could you bring back some napkins with you? I forgot to grab some." Keiko calls after them. There was a point in time where she honestly thought there was something between the two, but her match-making desires were quelled when it was obvious the two were really just good friends.

"Care to tell me what has you all wound up Boton?" Kurama asks, fixing the reaper with a hard look. The two were close, but he, despite how the others felt, that in the end her loyalties lie with Spirit world-who was pretty much still on his shit list. The gang had enjoyed a quiet ten years of relative peace, the occasional rebellion here and there, but nothing too world threatening. Kurama, more out of his calculating need to be in control, often handled things for Koenma, so that his friends could cleanse themselves from the dirty corruption of Spirit World; he would not have this threatened. "Now Kurama, it's nothing like the Red Butterfly case," three years ago Kurama had cleaned up one of Koenma messes involving a semi-legal human trafficking ring that was a pain in the ass and he made sure he was paid handsomely. "I honestly don't even know how to go about this, or where to start for that matter-how we missed this is beyond me, really Koenma has gotten better-don't give me that look, you do have to give him some credit."

"Fair enough, so then what is it?"

"Hiei-he, uh, well, he needs to tell Yukina the truth"

"And exactly why would I do that, onna?"

"Aaa!" Boton screams, diving for cover behind the fox."Hello Hiei, this is a pleasant surprise, I didn't think you were going to join us."

"Hn. Must I repeat my warning to you?" HIei ignores Kurama, glaring at Boton instead. Boton thinks back on his warning during the Dark Tournament. "Well...you see…" Boton peeks over Kurama's shoulder, "You sorta don't have a choice, Hiei." The dragan pins her with another warning glare, and Boton seriously thought she was about to die that moment. Stuttering she explains, "If you don't tell her, she will find out-not because we tell her!" "Hiei, let her explain, surely there has to be a reason." Kurama holds out his hands, trying to keep him calm. "And what reason could that be? Why would Yukina knowing the truth be such a necessity?"

"Because you have a younger sister." A moment of silence. "What do you mean? Are you inferring that Hiei has another sister?"

"Yes."

"Impossible, I only have one sister and that's Yukina"

"Oh!"

The three turn to see Yukina standing in the doorway. Well shit. I'm dead, Boton thought to herself before heading over to catch the ice maiden as she fainted.
