The invasion on Konoha still takes place but no shinigami during the fight between Orochimaru and Minato. But Minato does deal a considerable damage to Orochimaru and giving him a seal that would cause him a bit of trouble.
It's almost three weeks after the invasion that Iruna notifies Minato about finding the Kyuubi. She finds the Kyuubi inside a mountain and was miles away from any villages. Their plan comes to play Minato leaves Konoha for a while saying he had business to attend to. He brings Tenzo with him and Iruna suggested to bring him for a bit of help with restraining the Kyuubi.
Jiraiya comes to the village at the same time Minato leaves so as to have someone with equal power with Minato to keep Konoha safe since the village was still recovering from the invasion.
Iruna meets Minato by the entrance with Koushi next to her. Irunas' clothes have changed, the kimono shirt she wore was of red with black flames as the design and from pants. She now wore black fitting shorts and heeled boots. Her arm bands are gone revealing her chakra tattoos, but she wore two beaded bracelets. Her scrolls and weapon pouch gone.
Iruna nods at Minato, and Tenzo under orders of the Hokage refrained from asking questions. He was only told to assist the Hokage. The four of them enter and once they reached the inside and the Kyuubi resting or so he appears to be. A few steps towards the Kyuubi, his eyes snaps open and unleash an attack at them.
Iruna and Minato tag team with their sage mode, Iruna going all out using the third stage which caused her braided hair to gain red and orange streaks in her hair. Koushi and Tenzo were back up while Iruna and Minato as the main attack force.
Irunas' main seal she used were the chakra chains. Of course, that had surprised Minato as Kushina used chakra chains. Tenzo helped with restraining together with the chains. Iruna had given Koushi chakra chain seals to activate as well to keep the Kyuubi subdued.
With the Kyuubi chained down, Iruna and Minato began with the sealing process. The sealing went smoothly, Minato gaining tattoos from his stomach to his arms and falling unconscious after looking at his the seals.
Tenzo followed suffering from chakra exhaustion. Iruna from the long usage of the third stage, Tohru had told her she was only to use it with 30 minutes as the longest, but she went beyond and strained herself. Koushi...remained fine and called on Tohru for help.
Because of the sealing and only Jiraiya knowing of his plans, was told that if Minato doesn't return within a set amount of time... which does happen as the old toad sage fears. Minato goes missing alarming the village, worrying Naruto, Kakashi, and Obito a lot.
Jiraiya is told to be the 5th Hokage which he refuses like in the story and drags Naruto to come with him to look for Tsunade. Naruto refuses at first since he believes his father is still the Hokage and isn't dead, but Jiraiya has his way of convincing him saying that Tsunade was just going to be a substitute until Minato returns so no one else can take the position. Naruto agrees to go.
Orochimaru... even as he manages to remove the seal, it caused problems to the chakra channels of his hands and heads out to search for Tsunade. Naruto does his bit, learns the rasengan bec of Jiraiya and drags Tsunade to Konoha making her the 5th Hokage.
Iruna meanwhile worries over Minato as he wakes up to eat and do exercise before meditating to visit his mindscape or the seals mindscape to gain the kyuubis approval to use his powers. She wanted Minato to go back, but the blond Hokage said that if what she said was true he would have to master the Kyuubis power before Madaras return. She goes between the human
and avian realm to relay information to the Hokage if he doesn't hear anything from Jiraiya. Tenzo...is poofed back to Konoha without a problem and a seal on his memories placed by Iruna.
Time skip...
Itachi learns a lot from Tsunade from observing during Tsunades treatments or surgeries and Sakura... does learn medical ninjutsu, but Itachi beats her as a genius he is, not to mention he got into anbu. He goes on missions with Hyuuga Haru at times after hearing from Haru that he comes across Iruna during missions, so far he hasn't met her yet.
Sasuke has gotten better with seals and using the seals he made to fight with taijutsu and ninjutsu. Even making use of the chakra repressors when he uses taijutsu, if he lands a clean hit on the real body he can prevent them from using ninjutsu. He's good with his taijutsu thanks to Tenten, Neji and Hinatas help together with Rock Lee and add Hyuuga Haru.
Naruto... you guys know the story, dont need elaboration.
Iruna still does as pseudo Madara asks...that is until pseudo Madara tries to kill her. She escapes death from pseudo Madara thanks to Shisui taking the fatal hit for her. He gives her both of her eyes and has her escape before he makes use of a suicidal ninjutsu to buy her time.
Sasuke during a mission loses his eye sight after protecting his teammates with his seal. He's following in Irunas' footsteps, but can we avoid with the frightening injuries? Iruna drops of Shisuis' eyes to Itachi without him knowing to help Sasuke, and a seal that would help Sasuke during fights. A simple seal in his level he could use.
During the shinobi war, the bubble jutsu user, Fu, and the red haired old man shows up as the forces were getting overwhelmed. Using their tailed beast mode they helped the shinobi forces.
Obito gets brainwashed by pseudo Madara, and still becomes the host for the ten tails. Iruna shows up with Minato helping deal with the attacks, ya know just like in the story. Iruna is in her third stage sage mode and her mangekyou is active. She protects Sasuke and Itachi who were open as they were dealing with a few of the tailed beasts that were controlled by the ten tails. She tells Itachi to support her and Sasuke, as she'll take his place with attacking.
During the battle in protecting Itachi and Sasuke, and attacking. She had taken a blast head on using a barrier seal and reinforcing it with nature chakra. The barrier worked, but she had gone over the limit of her use of the third stage, and the strain had gone to her body and chakra channels already. She was able to last longer due to her will and thought process, but even with that it was already too much.
Itachi tries to heal her or get her out of the frontlines but there was another incoming attack. Minato and everyone else had their hands full with avoiding or deflecting the blasts. Iruna had to make her next move count to help everyone else. What she had left was a forbidden jutsu..she was warned against using the jutsu.. while it was considered a devastating attack the price to pay was large. She wanted to live through the battle to see what happens to her brothers and the future, but they had to survive the incoming attack. She knew Sasuke would play a role in facing Kaguya since they were still facing the ten tails. It was a gamble.
"Sasuke, you better become a fuinjutsu master, a better one than me! Itachi...you've already mastered medical ninjutsu, dont get bored of it okay? Watch Sasuke like you always have. You did a good job." Iruna tells them before she goes through the hand seals of the forbidden jutsu as fast as possible. The requirement to even use the jutsu was for her to be in third stage mode. She went through the seals and a reddish light came from her form and her eyes glowed red around her pupil. "Phoenix blast"
The forbidden jutsu is like a kamikazee that she can focus towards one direction but on a gigantic scale, and as she had her mangekyou on the flames of the kamikazee were black, the Amaterasu, and red orange for the forbidden jutsu. The price for such a jutsu though was all of her energy. Her chakra, the nature chakra that flowed into the tattoos and the chakra that sustains her body.
As she finished the seals, flames burst from the ground and at the ten tails black and fire red flames. She didn't get to see how it went as the light around her disappeared, she was gone as well.
Kaguya was defeated as in the story and peace was back. Minato took his role as Hokage back while Tsunade took akick back and worked at the hospital. Minato stayed as Hokage, until he decided to pass it on to Kakashi.
Sasuke under Minatos guidance and with Irunas notes given by Minato earned him his name as a fuinjutsu master coming up with seals, his sharingan helped him that. Itachi often having to heal his brother if there were any explosions from his seals that he couldn't avoid. Itachi...stuck as the medic for his sibling, but he didn't mind and he taught at the academy too when he wasn't at the hospital working.
What happened to Iruna? She woke up in the avian realm called as Your Highness, or Princess. After using the forbidden jutsu, her body was destroyed, but the user would be reborn as among them in the avian realm. Avian ascension... that is what the avians sage mode is called. One is worthy to be of their kind if they have reached stage, and upon their deaths they are given a choice to be in the avian realm or to move on. The forbidden jutsu...can only be used by those worthy to be an avian and those that have the will to wield such power were awarded withequal power in the realm.
Hence, as she woke up, she wasn't human, but of a phoenix and... together with Hoshi and Yuta were the only known living phoenix in the realm. She gained to older brothers in the avian realm, and with her memories in tact... along with Yutas'. Yuta smiled widely at Iruna or newly cristened as Riuna would tease her non-stop about a chance with Koushi. Hoshi, of course knows of Irunas admittance back as a summoner and told her that the agreement still stands.
As in their realm the souls are recognized and not their chakra. Now it was official that she and Koushi are engaged .Iruna isnt sure about the engagement as she had said those words in a spur. She suggests to Koushi to dissolve it, but two parties would have to agree.
Koushi refuses to dissolve the agreement and tells her that as he stayed by her side. He had truly fallen in love with her. It takes a while for Iruna to sort out her feelings, but she admits she also fell for him.
Yay, happy end, and yeah...I know.. why did I include a romance part for Iruna? Well, it started with that freaking fiance thing. I swear I dont know why I placed that in. At times i think this story writes itself more than me doing so.

Omake
Sasuke on the day of his fifteenth birthday. Itachi had given him a scroll and scrolls on fuinjutsu that was included in Irunas' belongings according to Namikaze Minato. Sasuke as he studied seals checked on the scrolls before looking at the larger scroll. He read the names of those that had signed the scroll before him and found his sisters' name, with his eyes sparkling he signed his name next to Irunas'. It was seconds later that the sight of the scroll disappeared and he fell into hot water. Shouts could be heard and water splashed around. Those that had been taking a bath, one of them recognized the new guest and lead Sasuke to the palace where Iruna was on her way to meet Hoshi and saw Sasuke.
"Sasuke!" Iruna shouted glomping his little brother, but the guy didn't recognize her and he also wondered how she knew his name. "Nice to meet you! My name is Riuna, here!" She grabbed his hand and placed her feathers' into his hand.

This is part of the epilogue that I made.
POV: Iruna
I had been going back and forth to Konoha to check on everyone. It was nice to see how it has become peaceful. I was in my human form, and my appearance was different. Though it did make those I bypassed look at me for my bright red hair, you don't see people with red hair that often. Out of nostalgia, I went to Ichiraku ramen and found a son and father pair present.
I took the seat next to the son and ordered one bowl of ramen to eat. While eating, the son had turned to me and noticed my red hair.
"Uwah! You have red hair like my mom did!" He said. "Do you have Uzumaki blood?"
"Eh?" I turned to Naruto, he got older, but his attitude remains the same. "I don't think I am related to any Uzumaki." I said to answer his question.
"Sorry about that." Minato seating on Narutos' other side said. He got older, as expected. He stared at me a good deal...I felt like he was scrutinizing me that moment. "Are you related to the Uchiha?"
"In a different, lifetime maybe I was." I said humoring him. "I've had red eyes with tomoes in them as long as I can remember."
"I see. Ah, I'm Namikaze Minato." Minato introduced himself to me.
"Uzumaki Naruto" Naruto said grinning widely. "Who are you Neesan?"
"Me? I'm Riuna." I answered smiling. "Nice to meet you both."
"I don't think I've seen you in Konoha before." Naruto said.
"I travel a lot. I've been to Konoha a few times. I love how it's surrounded by trees."
"How do you get by?"
"I sell the storage scrolls I make." I answered.
"You're a seal maker like that bastard?" Naruto said.
The bastard must be my dear little brother.
"Maybe? I prefer to sell storage scrolls than any other seals out there. They're useful both to citizens and shinobi." I answered.
Naruto left ahead of us as he had a sparring session leaving me with Minato-san there.
"Welcome back." Minato said drinking his glass of water.
"Thanks." I answer smiling. "I'll be visiting more often."

Owari. Arigatou and Sayonara, Iruna. It was fun.
