"Looks like what the rumors say were true that you are a very formidable warrior, Shin Aisora." Ikkaku said his head shining when being struck by the light.

"Hey, what's the big idea of transferring the Living world's sun inside the fourth division's training grounds? My eyes hurt." Shin answered while covering his eyes.

Rangiku, Toshirou, Kira and Hisagi who just came out of the fourth division after visiting Momo heard what Shin said. All of them except Toshirou, who was smirking, laughed.

"Say that again?" Ikkaku shouted angrily.

"I said, that I think someone transferred the living world's sun here in Seireitei. Please put away your sword it might hurt someone or worse yourself. Those are not things that are just swung around." Shin answered.

"Why you, my head is not the sun. I'll show you some manners." Ikkaku said as he was about to raise his sword as Shin was putting down his things.

But Shin disappeared and the onlookers where speechless at what they saw.

"Fast, that was very fast." Ichigo said. He, Chad, Uryu and Orihime were being toured by Rukia and Renji when they saw Shin kicked Ikkaku's leg from the back and then stepped on his sword's sheath knowing that it may be used as a counterattack and then grabbing Ikkaku's hand that was carrying the sword and jerking it downward until the sword's blade was touching Ikkaku's throat. The result Shin was behind Ikkaku who was kneeling, Shin's right foot stepping on Ikkaku's sheath and his left hand holding Ikkaku's sword together with Ikkaku's hand and the blade placed on Ikkaku's throat.

"Hey, I told you didn't I? You might get hurt when you swing carelessly." Shin said cheerfully as he let go of Ikkaku and proceeded to pick his things up again.

"Lucky! Lucky Lucky Lucky!" They heard Ikkaku sing while doing his lucky dance.

"Shimatta, I think I got a little overboard again. You think he lost it?" Shin asked Kirio.

"It looks like it." Kirio replied.

"He did lost it!" Shin exclaimed when he saw Ikkaku standing only on his Toe fingers.

"Nope, he didn't. That's his so called lucky dance. He does that everytime he finds a strong opponent." Yumichika said seemingly appearing out of nowhere.

"You mean that thing he was doing was a dance? He looks more like a lunatic." Shin said wide eyed.

'What the hell's with these people, one dance like a lunatic and this one has feathers on his eyebrows. And they say I am weird.' Shin thought as he looked at Kirio who had the same 'WTF' expression upon seeing Ikkaku and Yumichika.

Then Ikkaku stopped and faced Shin.

"Now, let's see who's stronger shall we? Nobiro Hozukimaru." Ikkaku shouted.

"Oi oi, Ikkaku are you nuts? You wanna fight a shinigami who is already passed taichou level and a royal guard who was able to take on two taichous at the same time and even hurt Aizen?" Ichigo asked.

"Save your energy Ichigo. When Ikkaku-sempai sees a strong opponent, he won't stop until he is able to fight him." Renji said.

"Gomen gomen, but I don't like fighting fellow shinigamis unless they are on the enemy's side. So, please find another opponent." Shin answered while walking away.

Ikkaku suddenly attacked him intending to impale him using Hozukimaru. Shin tilt his head a little to the left just enough to prevent the blade to stab his head.

"Your one stubborn cueball are you?" Shin asked.

"Who are you calling cueball? Enough with your mindless chatter, show me what you got or is the rumors just lies?" Ikkaku taunted.

"Maybe they are lies maybe they are not. If you really want to know then show me your full strength, then maybe I might show you a glimpse of mine." Shin answered.

"What are you saying; I am using my full strength." Ikkaku said.

"Really? I don't think so; you are not in your bankai yet." Shin answered.

"What Bankai are you saying? I don't have one." Ikkaku said.

"Oh I see, hiding it eh? I'll tell you something then. You are hiding it poorly. You see shinigamis who have been taichous or higher for a long time can easily detect the level of the reiatsu of a soul, especially when that soul is not very good at controlling his reiatsu. Sadly, you are one of them. If you're not going to use it against me then you're not even worth the bother." Shin replied.

"Are you afraid of losing to someone who is not in Bankai?" Ikkaku asked.

"Iie, I just don't like to waste my time on shining the floor with your head and your blood as the wax." Shin answered as he and Kirio was about to left the fourth division grounds.

"Ha! You can escape me now, but I will haunt you till you give in to my challenge. Even if I had to beat all those from your division till I get up to you." Shin stopped when he heard Ikkaku said that.

"You don't know when to stop are you, Mr. Cueball?" Shin asked. His voice is not cheerful anymore.

"Of course." Ikkaku boasts.

"Kirio, please hold unto this for a few seconds." Shin said as he handed his things to Kirio.

"Now, we're talkin'" Ikkaku exclaimed.

"Baka!" Shin suddenly disappeared and before Ikkaku could react he was already sent flying backwards by a knee kick in the gut. His flight was stopped by a large rock, where he collided and was buried in the shambles. Ikkaku moved the pieces of the rock so he could stand up but he was a little hunched because of the pain in his gut and said.

"What the… Atleast say start or give any indication that it is—" Ikkaku's words were cut off because Shin was already over his head and kicked him on the back of his skull which buried him on the ground face first. Shin then grabbed the back of his kosode and then his neck. He raised Ikkaku until they were looking eye to eye.

"We are shinigamis not street brawlers who just fight because we want or it is fun. We fight to kill and protect. There is only one rule we follow on a fight and that is 'Be sure we win'." Shin said as he threw Ikkaku upward. Shin appeared on top of Ikkaku and then hit Ikkaku's back with the heel of his foot.

As Ikkaku was falling downward, he appeared at Ikkaku's back and said.

"If you're purpose to be a shinigami is just to have some fun in your fights then quit because we are fighting for something much bigger than your fun." He rode Ikkaku like a snowboard as Ikkaku reaches the ground till his skid stopped. Ikkaku by now was down face first in the ground. A trail was formed where he had skidded. Shin then stood up and walk off Ikkaku's back and stepped on Ikkaku's head which resulted in his head being buried to the ground.

"Don't try initiating a fight against me again nor trying to initiate a fight on my division because if I see you harassing anyone of them…" Shin said. He grabbed Ikkaku and then dropped him so he was lying on his back. Then, Shin got closer and whispered into his ear.

"I'm going to make sure that waxing and shining the floor with your head and blood will be your least of worries. I'm sure the twelfth division is in need of some shinigami body parts, ne?"

Ikkaku through bleary eyes looked at Shin. What he saw though wasn't the cheerful and childish keishu but a dead serious assassin.

"Sugui, this is the first time I saw Ikkaku-sempai gets his ass handed to him and not being able to even fight back nor land even a single strike." Renji said.

"Now I have no doubt, he really is from Yoruichi's division." Ichigo exclaimed.

"What do you mean?" Hisagi asked.

"He is so much like Urahara and Yoruichi. Normally, they look goofy and carefree. They tease others, childish and even act dumb sometimes but then they will suddenly change personality to serious. When they are serious, they would beat the hell out of you at the quickest way possible then they would mess with your mind with taunts then they would change back to their goofy personality." Ichigo said.

"The most dangerous assassins are those who look the most harmless. I remember Kurosaki-taichou telling me that. I didn't know he was referring to the former 2nd division officers when he said that." Toshirou muttered.

Shin walked back to Kirio and took his belongings.

"Arigatou Kirio, let's go we have many thing to do." Shin said cheerfully.

"How you change from a small child to a serious adult then back to a small child attitude at a small amount of time still puzzles me till this day." Kirio said while looking at Shin.

"What are you saying Obachan? I am always serious."

Kirio sighs and just shook her head.

~/~/~/~

It was early morning; a week had passed since Shin was instated as the taichou of the 5th division. Momo was just starting to wake up. She heard voices talking inside her hospital room. Her vision was a little blurry from the much sleep.

"So, what do you think Unohana-taichou? Is she clear to go now?"

"I think so, Ai…" Unohana replied.

'Who is Unohana-taichou talking too? I couldn't see much or hear much yet. My senses are still asleep. That voice seemed familiar. Ai…? Aizen-taichou? Yes, that looks like Aizen-taichou's voice. So it was really just a nightmare. I guess I just hit my head hard. I was right Aizen-taichou would never die nor try to kill me.' Momo thought. Her vision starts to get clearer.

She saw someone whose back is turned to her. She saw the white haori with the kanji number five on the haori. She looked up a little and saw the man's hair was brown. Though, she was a little baffled as why her Aizen-taichou is wearing a sleeveless haori and kosode with a very big sash tied around his waist.

"Aizen-taichou?" Momo mumbled.

Both taichou turned to her. She was shocked. The taichou wearing the 5th division's haori wasn't her Aizen-taichou but another person.

"Yokatta, it looks like you finally woke up." Shin said cheerfully.

"Anou, who are you?" Momo asked.

"Ah gomen gomen, watashi wa Aisora Shin desu, atarashii Gobantai-taichou. Yoroshiku onegaishimasu." Shin answered cheerfully.

"What happened to Aizen-taichou? Where is he?" Momo asked worried.

"What was the last thing you remember, Hinamori-fuku-taichou?" Unohana asked.

"I'm not really sure." Momo answered uncomfortably.

"Ogenki desu ka. You look pale." Shin asked.

"I had nightmares." Momo answered.

"Could you tell us?" Unohana asked.

"Hai, it's not very clear but I think I remember some parts of it." Momo started. She looked and saw that they are listening.

"In my dream, Aizen-taichou was killed and then for some reason I attacked Shirou-chan." Momo paused for a minute to recall her nightmare.

"Who's Shirou-chan?" Shin whispered to Unohana-taichou.

"That's Hitsugaya-taichou of the 10th division. They were childhood friends." Unohana whispered back.

"Then, I followed Shirou-chan to the central 46. I saw Ichimaru-taichou in there and then he asked me to follow him because someone wants to see me. Then, I saw Aizen-taichou and he hugged me then he stabbed me and everything went dark." Momo finished.

Both taichous didn't speak but only looked at Momo sadly.

"Why are you the Gobantai-taichou now? What happened to Aizen-taichou? Did something happen to him from the ryoka invasion? Please tell me." Momo asked pleadingly.

"Sosuke didn't die on the ryoka invasion. So please rest for a while. We'll tell you everything when you when you're better." Shin answered.

Momo looked at the sad faces of both taichous and then it dawned on her.

"My nightmare… it wasn't actually a dream was it? It all makes sense now… Why I am in the fourth division when I didn't fought for atleast a month and why the 5th division has a new taichou…" Momo asked.

She looked at them and they were silent.

"I was right didn't I? I attacked Shirou-chan in a blind conclusion that he killed Aizen-taichou and then in the end, it was Aizen who betrayed me…" Momo said.

Both taichou was surprised at how Momo suddenly dropped the taichou after Aizen's name.

"Sosuke betrayed everyone. He betrayed the whole Seireitei together with Gin Ichimaru and Kaname Tousen. So, please don't be too harsh on yourself. Everyone was betrayed and fooled." Shin said while extending his hand reaching for Momo head to comfort her.

He wasn't very surprise though, when Momo swatted his hand away and scurried away from him. Sadness came upon Shin's face. Momo saw this and said.

"Gomen." Momo said not looking into his eyes.

"Daijoubu, daijoubu. Don't worry about the division for a while. I'll be taking care of it. So you just rest up, okay?" Shin said cheerfully.

Momo just stayed silent and still refusing to look at him.

"I better go. Many things to do. Unohana-taichou, please take care of Hinamori-fuku-taichou." Shin said while walking out of the door.

Once Shin was outside, he was about to walk out of the division when he felt Unohana-taichou's presence and she asked.

"Aisora-taichou, daijoubu?"

"Hai, daijoubu." He answered.

"Please understand, she is currently experiencing emotional trauma from what happened." Unohana said.

"I know, I'm not upset about her. If there is a person I am angry it is Sosuke. Momo-san wasn't the first one who was scared of me when I was announced as the new taichou of the fifth division. Everyone in the division practically couldn't accept me or more specifically can't trust me. What Sosuke did really traumatized the whole division." Shin replied.

"Give them time. Betrayal is something very hard to accept, especially when the very person who betrayed you is someone you pledge your whole loyalty and life."

"I know, I guess my work keeps on piling up huh? Oh by the way, we're you able to study the elixir?" Shin asked cheerfully.

"Hai, give me some more time and I think I could reproduce it. Some of the ingredients used are actually available in the mountains where I gather herbs."

"Yokatta, I hope it could be reproduced. Gomen, I am not really good at making herbal medicines or medicines of sort. I'm more on the gadgets and fighting. It's really good that there are divisions dedicated for research and relief."

"It's alright; not everyone could really be a master at everything. It takes years or centuries and being special to be that. We just have to do our part extraordinarily well and learn to trust others to do theirs."

"I guess you're right. Well I better go back to my division now. Many things to do, many shinigamis to befriend and gain trust." Shin answered.

"Good luck, Aisora-taichou." Unohana said before Shin disappeared.

"A hundred years have passed and you still like disappearing like that." Unohana smilingly said.

~/~/~/~

"Hadou #90: Kurohitsugi" A black energy starts to form a coffin around the training dummy but it dissipated before it even was able to complete the coffin.

"Kuso, I can't even form the coffin when I don't use the incantation. Even if I use the incantation, I can't attain the full power of a number ninety or higher hadou." Toshirou said aloud. He was currently at squad tens' training ground.

"You know, kido takes years or even centuries to master. It's a lot harder than practicing zanjutsu and hakuda. It needs very high concentration, reiatsu control and experience. But look at you; you were able to almost form a level ninety hadou without incantation at such a young age, truly worthy of the title Tensai Shounen." Shin said while clapping.

"Ohayo Gozaimasou, Aisora-taichou." Toshirou said. Truth to be told he was very grateful to Shin because he not only took over the 5th division so it won't crumble and that he was the one who gave the elixir to heal Momo. At the same time, he unintentionally made Shin his role model. By what Abarai told and confirmed by Ichigo and Komamura-taichou, Shin was able to stand up against two taichous at the same time while also being able to protect the others and even hurt Aizen, something he couldn't even do. Yes, he wasn't able to stop Aizen from taking the hogyouku but Toshirou doubt that any taichou could at that situation. To top it all he was once a child prodigy like him.

"You're too formal Hitsugaya-taichou, you can call me Shin or any nickname you think. I don't mind formalities." Shin answered.

"Really? But you just called me formally." Toshirou replied.

"Well, you don't like being called Shirou-chan, Shirou-kun, Chibi-taichou, Hitsugaya-kun or just plain Toshirou, ne?" Shin answered.

"How did you know those nicknames?" Toshirou asked.

"Did you forget that I was once like you? Well, I didn't mind being called Shin-chan or chibi-taichou or Shin-kun or Aisora-chan but I doubt the others would like it. And I kinda saw you reprimand Ichigo one time when he called you Toshirou." Shin answered.

"I see."

"Well Hitsugaya-taichou, I have a question for you. Why do you want to be strong? Is it to kill your enemy? To take revenge? Or just to beat everyone and be on top?" Shin asked.

"Off course to…" Toshirou didn't know how to continue. He closed his eyes and thought of why he wants to fight and get stronger. He remembered when he was still in Junrinan. He wanted to be accepted.

'I wanted to be accepted… no, I was fine being unaccepted by most as long as I have even atleast one person who would accept me.' Toshirou thought.

'That's right I became a shinigami, so that obachan won't be sick because of me. So, I could protect obachan from my own powers but obachan is dead now.' Momo flashed on Toshirou's mind. Matsumoto and the other shinigamis who believed in him even though, he was a child.

Toshirou opened his eyes and was about to speak but Shin stopped him.

"I'll teach you if you want. You don't have to tell me you're reason, I think I already know." Shin answered.

"You'll teach me? Like an apprentice?" Toshirou asked not believing what he heard.

"If that's how you call it. I personally think it's only a help from one taichou to another. So do you accept?"

'A royal guard is offering to teach me. I can't believe it.' Toshirou thought.

"So, are you going to accept? I think you'll learn a lot from him." Hyourinmaru said.

'But wouldn't it be confirming that I am incompetent?' Toshirou thought.

"I think not. And if you think you are then this is your golden opportunity to overcome that. Accept it Toshirou, you weren't really able to do anything against the betrayal. You may have known that there was something going on but you were still blindsided. Even in protecting Momo, you were no help at all. It was your fuku-taichou who stopped Ichimaru from impaling her and you weren't even able to scratch Aizen when he stabbed her. If you think you are incompetent then this is your chance to improve." Hyourinmaru finished.

Toshirou pondered for a minute and came to a conclusion that Hyourinmaru was right.

"Hai, I accept your offer, Aisora-sensei. Please help me get stronger and be more competent as a taichou. But may I ask something?" Toshirou said while bowing.

Shin raised an eyebrow at what Toshirou said.

"Uhh, I told you Shin is fine. Calling me sensei kinda makes me feel old. And yeah ask away."

"How can you be so sure about why I want to be stronger? I mean how were sure that my reason was not for my own gain?" Toshirou asked.

"Ahh that? Let's just say, your eyes isn't the same as mine. Gotta go now, I have to go and meet someone." Shin said as he disappeared leaving a confused taichou behind.
