Tengu

In the sky of Konoha, 4 figures are seen gliding across the sky like swift hawks.

"This is so amazing! Kyaaa!!!" Ino screamed out as she glided through the air, overlooking Konoha from a kilometre above.

"A-ah… So… scary…" Hinata's body was trembling, afraid to look down. Though her flight is steady.

Tenten looked the most natural, Tsuyu's eyes for talent wasn't wrong. In just an hour, she adapts so quickly, and her control and maneuvers… Tenten laughed out loud as if she owned the very sky.

The trio watch tenten in amazement as she draws an 8 shape in the sky, spinning in the air like a dancer.

Even Tsuyu is shocked inwardly, not expecting her talent to be to this extent. It seemed she recruited a hidden gem.

"Ah. Tsuyu! I am out of chakra…!" She wasted a lot of energy testing and performing various maneuvers at random. Tenten controlled her wings closer to Tsuyu. Tsuyu detaches a cable from her wing, then connects it to Tenten's Wing Unit. Chakra flows from the cable filling up the chakra tank. There's a chakra storage unit formed from sealing in each wing, helping to hold a fixed amount of chakra for the user.

With Tsuyu's enormous chakra in mind, Danzo naturally gave these designs, also allowing a longer flight duration. Danzo is definitely meticulous and detailed - a characteristic branched from his paranoia.

More of these sightings are seen each day. The Aerial Shinobi Unit made itself known for the whole of Konoha. Also, for other nations as there's always spies lurking among the civilians. Konoha showed this freely so that the local lords and Daimyo could gain confidence and support them with more funds, also letting more commissions come in from other smaller nations.

Onoki looks at the report in shock and worry. To think Konoha reached Aerial advantage. This had always been Iwagakare's confidence from their Reduced-Weight Rock technique.

Rasa also had a frown on his face. Konoha had gained small strength to fight against him. He is really considering to back away from war and really wants to sign a treaty with Konoha.

But… the Daimyo is madly pressuring him for war. Because in his words, their land is suffering from famine. That Land of Fire is forcing unreasonable prices on them and other countries followed suit out of greed. Their Daimyo had sent letters to reach a reasonable exchange. But Root operatives and greedy people behind the scenes always prevented this from happening. This makes the lords and the Daimyo of Wind really want to wage war to take a piece from the Land of Fire.

Tsuyu didn't know her idea to starve the Land of Wind cause them to completely consider waging war, not the opposite.

Raikage A smashed his table out of anger seeing Konoha gaining strength again.

"We cannot let them grow…" He gnashed his teeth.

In a few days, Tsuyu compiled the information on aerial combat on a stack of paper. With an experienced old military veteran that once held a position as a battalion commander under Danzo that would help her fill in the blanks. This would serve as an official Standard Operating Procedure for Aerial Unit. 

She put much detail on air combat manoeuvring, the art of moving and turning an aerial fighter based on her past life experience and adjusting them to fit into standard fighter jet like tactics. Considering there aren't that many aerial threats yet, she focuses on the important ones. The aerial units of other shinobi villages are elite and would only be deployed for strategic missions.

For basic maneuvers it can be categorised into 5. Lines (horizontal and vertical), loops (making a 360 degree turn), rolls, spins and finally hammerheads (heading straight up at 90 degree, then shifting path utilising the lowered speed).

These basics need to be mastered first before proceeding to anything else. 

Barrel roll to cater for access energy after acceleration, Immelmann turn for a smooth 180 degree bearing change, Split S to do the exact opposite of Immelmann turn, low Yo-Yo to sacrifice altitude for speed as it moves with gravity.

As the aerial fighter feels the wind with their own body, the feeling of resistance, touch, and gravity would accelerate training as it feels more natural compared to staying inside a vehicle where many senses of the body cannot be utilised. Formations can be simplified either sparse or tight.

Next she focused on Close Air Support - mostly launching strafe or airstrikes to the ground. Coordination between aerial units and ground units is crucial to prevent friendly fire and missing targets. Someone with training can be assigned as the coordinator and communicator called Joint Terminal Attack Controller (JTAC). These people will be assigned to give detailed instruction and information on what kind of support they need. A Yamanaka that could communicate long distance would preferably be given this role or through radio devices.

Thinking about it, the presence of Hyuga clansmen in each squad that can see the battlefield as clear as day, communication between Aerial Units and JTAC can be lax and independent actions can be taken without misfiring. 

She already planned to give Hinata Lieutenant position for her squad given she could see the entire battlefield with her eyes. Besides, she is very smart and can understand everything in a single hearing. Tenten and Ino being her acquaintance her age makes it no problem for her to communicate confidently too. Tsuyu knew she would be away half of the time as her real forte is as a frontliner so she had to hand over to Hinata whenever she went away.

Coming back to SOP, for basic strategies, aerial units can be deployed for various objectives. Precision strike support to target important structures, providing cover by fire, reconnaissance, and sky bombing.

Danzo as the Highest Commander of Aerial Shinobi Unit called for a meeting with the councils including Konoha Council and Military Council to spread new SOP and training to incorporate Aerial Unit in the army with the ground unit. He left it to the men under him to explain the thick documents. He's too old to talk too much. He mentioned Tsuyu as the creditor naturally, almost with pride in his tone.

Out of everyone in the meeting Danzo is the one who seems to regain his youth with an almost imperceptible smile and expectations. 

Meanwhile, Tsuyu is responsible for training the first company in aerial movements. She leads by example, using shadow clones of herself equipped with Wing Unit, a squad of Tsuyus flies in a V formation at the start.

The fourth shadow clone of Tsuyu explained to the company the actions being done by her and the clones as they move in the air.

The demonstration is almost bizarrely perfect and easy to understand with their own eyes. Danzo almost thought Tsuyu had a past life soul that had experienced aerial combat seeing her perform spins and turns at complex angles on the sky of Konoha as she wanted to show examples to them.

After demonstrations, the shadow clones act as coach for each squad, accelerating their training unreasonably with personal close guidance from a hidden top expert.

Danzo initially Aerial Shinobi Unit doesn't actually require much development nor tactics since aerial advantage already made the unit a monster in the shinobi world.

In his imagination, they would just swoop down from the sky and blast people to death with explosives from above simply. But Tsuyu overturned his views. At this rate… Konoha's Aerial unit would surpass Iwagakure Weightless Corp and perhaps… even Kazekage would fall without the need of a Kage tier combatant to fight him once he comes out.

No, in a sense this aerial shinobi unit, even as a mere 12 member company at the moment, represents a Kage tier level power with its absolute advantage. Not to mention it's a teleporting aerial unit with Tsuyu holding Flying Raijin. Danzo shuddered at the thought himself.

Danzo wanted to give the first Company of Aerial Unit a special name. He decided to give them the name - Tengu. They are warriors of the sky, wings of the Leaf.

He doesn't know how many times he can feel surprised at her. At times Danzo wishes there's more of her since she's been carrying too much on her back, and there's not enough hands, not enough people with her genius that could come up with so many things and execute them in perfection. 

Especially for training a completely new subdivision and combat style - wait. Who says there's not enough Tsuyu? There's more of her with her shadow clones, guiding the new subdivision to become complete in a matter of a week. The efficiency is almost too terrifying, with Danzo giving greenlight on every matter Tsuyu headed making it even smoother. 

Tsuyu's original body coached her own squad members meanwhile.

"Next we will do a hammerhead manoeuvre." Tsuyu took the lead as she shifted to face upward. Her body moves at a 90 degree angle, eventually losing speed and coming to a standstill for a second. 

Hinata, Tenten and Ino followed suit. Albeit there's delay and discoordination, all of them reach the same point as Tsuyu. Each tilted their body down and dive straight to the ground at high speed before re-entering a different flight of path led by Tsuyu. All of them had their hearts racing in excitement. The thrill of air maneuver is a rollercoaster.

"Not bad. Tenten, you learn very fast. You are a genius." Tsuyu praised her genuinely. She's a natural at this.

Tenten felt pride blooming in her heart. No one has ever called her a genius. Even back in the academy she has always been seen as average, easily forgotten.

"It's thanks to your teaching Tsuyu!" Tenten replied. Hinata and Ino felt a little competitive seeing Tenten do so well and practice harder.

People of Konoha often talked about their sightings. Naruto wanted to join, many other shinobi aspired to reach the sky as well. But without any surprise Tsuyu rejected him blandly.

After a full day of being busy, she finally returned home before the sun set. She sees Naruto lounging in the living room, watching TV. 

"Nii-san, next week I will hold a training camp. You will be joining. You need to be shaped properly. I already talked to Kakashi and Jiraiya about the matter." Tsuyu said blandly.

"Huh? Training camp? But I am already training with Ero-sennin." Naruto lazily replied.

"He won't be able to give you what I can offer. If you want to become strong, you have to join. We will be camping in the Forest of Death for a whole week and undergo intensive training. There's a hundred or so participants so far. Ino, Tenten and Hinata will be joining. Oh. Kiba as well."

She recalled the Inuzuka matriarch meeting her by chance at the grocery store earlier. She asks her to beat him to turn him into a real man. Tsuyu naturally took that job seriously. She will give special beatings to him.

The heads of the clans are briefed on the details of the training camp, posters are also posted on the street of Konoha to invite Shinobi of all ages and ranks to join.

The camp is called…

"Hell's Week"

It offers gruesome, intensive, challenging, stress inducing training to prepare you for war, to turn you from a rough rock to a gem. To sharpen a dull edge into a lustrous sharp one.

Also, you can retreat from the camp whenever you want if you cannot handle it. Health status is constantly monitored to ensure minimum safety. Due to the training camp being entirely voluntary, and the participants can quit anytime with Danzo promising Tsunade of its safety she acquiesced. Besides, on the first day itself a lot of people would quit in her opinion. And it's only a 1 week camp, as Tsuyu reduced the duration to cater for Konoha's need to send shinobi to missions. There's two sessions planned for it so those who missed later.

Naruto didn't know what literal hell was waiting for him. Tsuyu already planned to give Naruto twice the beatings as Kiba's because 9 tails makes him recover multiple times faster than ordinary people.
