AN: Spin-off of my That Which Cannot Be Seen fic.

Genryusai and Chojiro

The Soul Society was flourishing. The Gotei 13 had been established for a few centuries now. They even started a Shinigami Academy. All of the Gotei 13 squads have a captain now, some even have Lieutenants. Well, almost all. The 1rst Division still does not have a Lieutenant. Nobody had been strong enough to stand in Genryusai Shigekuni Yamamoto's presence for very long. His spiritual pressure was just too much for the Shinigami, so far, too handle, until now that is.

Genryusai Shigekuni Yamamoto was in his office when there was a knock at the door.

"Enter." Genryusai calls out, not looking up from his paper work. The person enters and walks up to his desk. They do not say anything. Genryusai would have thought nothing of this had it not been for his Zanpakuto. Now people know that he has the most powerful Fire-Type Zanpakuto in the Soul Society, but what they do not know was his Zanpakuto was bored. Ryujin Jakka, his Zanpakuto, was only close with only a few Zanpakutos. So, having Ryujin Jakka take notice of this person was telling, and interesting to Genryusai.

He decided to look up and what he saw… was breath taking. He saw a man, not much younger than himself, with short white hair. He was wearing the standard Shinigami uniform. His Zanpakuto was sealed as a katana at his side. And what was amazing was, Genryusai could see this man's Zanpakuto spirit. Only soulmates can see another's Zanpakuto spirit all the time.

"Hello. It's nice to finally meet you." The man greets in a soft, almost shy, voice. Genryusai shivers at how sensual his voice sounds.

"Hello. Now, who might you be?" Genryusai asks, while standing up from his desk and coming around to stand in front of the man.

"My name is Chojiro Tadaoki Sasakibe. Shunsei and Jushiro thought it would be a good idea for us to meet." The man, Chojiro, explains.

"Oh, they did, did they? Those brats." Genryusai grumbles with affection. They were interrupted by their Zanpakutos.

"Hello there." Ryujin Jakka greets, as he moves over to the other Zanpakuto. "What is your name?"

"My name is Gonryomaru." The other Zanpakuto, Gonryomaru, answers. "What's your name?"

"Ryujin Jakka."

Genryusai and Chojiro watch as the fire dragon seduces the lightning unicorn. (Think Ixion from Final Fantasy X).

"I have come to apply for the position to be your Lieutenant." Chojiro states, getting done to the real reason he was there.

"Is that so? Even though you are my soulmate, you still need to prove yourself. No favoritism." Genryusai says. Chojiro nods in agreement.

"I would not have it any other way. I will prove, not only am I good enough to be your Lieutenant, but also good enough to be your mate." Chojiro declares, with determination. Genryusai smirks, liking his attitude.

"Alright then. Let us go to the 1rst Division training grounds." Genryusai orders. They Flash Step there.

-1rst Division: Training Grounds-

Genryusai and Chojiro were standing across from each other on the training field.

"Show me what you got." Genryusai orders, as his spiritual pressure rises.

"I will! I will show you everything I have!" Chojiro yells, as his spiritual pressure also rises.

Holding his Zanpakuto he lets loose a cry of… "Pierce!" His Zanpakuto becomes a rapier. He charged at the captain thrusting his Zanpakuto at him.

Genryusai smiled and dodged his attack, flash stepping from side to side. Chojiro used his own flash step and tried to thrust his blade at the other male. Genryusai vanished and appeared behind him and poked the back of his head.

"Your skills are impressive." The man says.

"You haven't seen anything yet." He vanished and began to dash about using flash step. Genryusai was following his movements, but he missed one thing what he was doing with his sword. He dragged it along the ground causing sparks to be released.

'Hmm?' He cast his eyes down and Chojiro had completed a seal.

"Lightning Dragon Coil!" He pierced the ground and completed the circle with his sword, like a missing piece of a circuit and flash. Lightning spiraled in to the center and hit Genryusai. 'Did I get him?'

The smoke cleared and Genryusai was hit, but only his clothe was destroyed, his sexy ripped form was exposed to the other male. Chojiro blushed. 'So ripped, so manly, so hot!' He felt his insides get all tingly and felt his blood rush south.

"Not bad, my turn." His staff reverted into a sword. Chojiro jumped back, his sword crackling with lightning. He thrust his sword and fired a bolt of lightning. Genryusai countered it with his Zanpakuto. "Like I said my turn!" He released flames that spread out reaching and spreading completely cutting off Chojiro's escape. The flames drew in, and swirled and Chojiro let out a gasp.

When the flames vanished Chojiro was bare ass naked. Genryusai chuckled as the male shielded his crotch. He had missed out on the best bits, but it was still a lovely sight. "You could release your Zanpakuto without a command?"

"Indeed, when reaches a bond level of a Zanpakuto they can reach new heights, dispelling the limits and obtaining the power of Bankai."

"Bankai?" Chojiro stared at Genryusai in awe.

The man nodded. "Yes, I look forward to seeing your Bankai, and more of you." He appeared next to Chojiro and playfully groped his ass. Chojiro gasped.

"Y-yes!" He coughed. "I mean yes, I promise I'll show you my Bankai one day."

Genryusai and Ryujin Jakka are so happy not to be lonely anymore.

-Present Day-

Genryusai was looking over the Soul Society from the windows in his office when he felt a familiar spiritual presences. The person walks up and wraps their arms around him.

"Staring over your domain, Koi?" Chojiro teases. Genryusai laughs.

"Technically, the Soul Society is the Soul King's domain." Genryusai says. Chojiro chuckles and shakes his head.

"Sure, but who actually takes care and protects this place." Chojiro states. "You do. You care about all of your subordinates."

Genryusai turns around in Chojiro's arms, and pulls him into a hot, passionate kiss. He runs his a hand through, Chojiro's soft, short white hair. After a moment of making-out, he pulls back and looks at his soulmate lovely.

"Oh, my beautiful soulmate. My Lightning Unicorn. You have always been there for me, even in, some, of my weakest moments." Genryusai says, in awe. Not believing he had such a loving, supportive soulmate. Chojiro cuddles up to him.

"Of course. I will always be there for you, my Fire Dragon." Chojiro sighs in pleasure. They stand there in each other's arms, looking over the Soul Society. Thinking about what the future will hold.

Ryujin Jakka and Gonryomaru laid together watching their owner's in pleasure. Hoping that the future will be just as bright.

'It will be, as long as he is here with me.'
