Kara

****************

A few days later, after Sumire Kakei resigned from her genin team to join the Scientific Ninja Weapons Team, Rosé was sitting at lightning burger with the group when Tsubaki the new member of Team 15 showed up and was picking a fight with everyone , after that most of them left leaving Sarada and Rosé alone , Rosé then spoke to Sarada who had her head on his shoulder .

The next day they had a Farewell party for sumire and everyone one had gathered and congratulated her and wished her luck for her journey ahead .

*****************

It was the next day and we were having breakfast , when Hinata informed us that Grandpa Hiashi's Birthday is coming and they are going to have a party .

That day Rosé was sitting with Boruto and Mitsuki trying to figure out what grandpa likes and what to get him as a present ,they were stopped by a commotion occurring , it was a man who was bad mouthing Grandpa and the village.

Rosé then walked up to them and said " oye come outside for a second "and then walked out , they followed him and as soon as they reached a dark alley Rosé used [Omnikinesis] to squash them to the ground and then put his leg on thier face and said " you should watch your tongue or you might just lose your head ".

And then went away ,the two people had pissed themselves because of the blood lust Rosé released.

The next day they went on to celebrate grandfather's birthday at his house and he really enjoyed himself.

*******************

A month had passed ,and Rosé was summoned to the Hokage's office over there he met sasuke , who told him that the s - rank mission that he had completed , the boss of the mujina bandit had some information about the mark on Boruto's hand and a new organisation that had been in the shadows that is related to the mark in some way, "Kara " that was the name of the organisation .

Rosé had then been sent to Amegakure,with Sai sasuke and Team 25 ,they had found the location of Kara's Hideout based on the information they received from Shojoji , The building used to be a sewage treatment facility, until it was abandoned due to a toxic gas incident that caused several fatalities. They also hand them a map of the waterways. Sai congratulates them on their intelligence work, and requests them to notify the nearby Anbu teams that he,Sasuke and Rosé will continue alone.

They then entered the Hideout , Sai notices that building hasn't progressed in Amegakure. They venture inside the building, and notice that someone is watching them ,after that when they open a door they trigger a trap , which releases smoke , the person thinking he got them came out but didn't find anyone there , Rosé and the others were standing behind him ,sasuke ask him who he is ,not answering he tries to attack them but is pushed against the ground by Rosé using Omnikinesis,

The man accuses them of killing his friends, to which Rosé tells him that they are shinobi from the konoha .

The man introduces himself as Garashi Tōno. He explains he learned ninjutsu from an old man who raised orphans like him who lost their families during wars.

Garashi isn't sure when Rosé asks about Kara, but recognises the name, and shows them a design he copied from them.

He told them that it seemed like they were doing some sort of experiment ,but they spotted them and one after the other his friends were swallowed up by the poisonous gas .

Garashi asks them to help him recover his friends' remains in return. At the hideout, Garashi warns them not to wander in side paths, and that depending on the airflow, the places with poison gas changes. They arrive at a blocked passage, which Sasuke breaks open with Chidori. Garashi rushes in,Rosé,Sasuke and Sai follow him inside , when they arrive the see Garashi laying on the ground but when they approach him it turns out to be a clone , The room is then filled with poison and trap's trying to bind them go off , Rosé avoiding all of the traps dispels the poison around the the three of them , Garashi then come in wearing a gas mask and reveals he killed his friends with the gas and that Kara gave him hope ,Rosé , Sasuke and Sai then acted like the fainted, seeing this Garashi went back up , where The real bodies of Rosé , Sasuke and Sai were waiting for him .

Garashi tries escaping, but begins to suffer the effects of the poison gas, he refuses to let Konoha learn anything, and kills himself. The building begins to collapse, They spot some of what remained from experiments, but can't investigate, Rosé then uses space-Time Ninjutsu and teleports them out , They conclude that not only they confirmed that Kara actually exists, but also that they have sympathisers.

They the went back to Konoha were they gave Naruto a report of the situation , Sasuke adds that Kara's experiments are likely biological, as he's seen similar equipment when he was with Orochimaru. Sai asks if Naruto saw Ino's report on Katasuke. She was able to determine a third party had been influencing him. Naruto wants to reinstate him, as testing without him has slowed down considerably, something they can't afford when their work has been leaked.

*******************

The next day , Rosé was told to follow Team 7 on a mission, assigned a missing person's mission in the Land of Valleys. They're joined by a recently returned Mugino, who is familiar with the region, He then explains About his mission he spent the last few years mediating conflicts between smaller nations.

They reach the Land of Valleys and report to Mia, who requested the mission. The missing person is her husband Anato, a researcher for a medical supplies' company. He was supposed to have return after a one month work related trip, but it's been three weeks since his intended return date, and the company won't divulge anything due to trade secrets.

They go to the company where Anato worked. The receptionist assures Mia she'll be updated, as they have also sent a search party to look for Anato. While a distressed Mia makes a scene, Mitsuki has a snake look for information. He manages to learn where the company's search party was sent to look for Anato, a place he told Mia about. Rosé notices Someone is watching them from a distance but decides to ignore him . As they reached the destination, they were surrounded by other shinobi,it was victor the head of the company And his group, Victor then tells his people to stand down , Victor then goes on to tell them how he was researching Regenerative therapy to help everyone …..

They then went on to look for Anato ,they then enter a cave searching , where they find massive roots ,they then hear a voice coming from deeper into the cave and go on to check ,when they enter they find Anato, he was extremely pale looking and was grunting in pain , his whole body was shaking ,He then attacked them by extending his arms like rubber , They dogged his attack but the attack still grazed mitsuki .

Rosé then goes on to restrain Anato using Omnikinesis ,after that victor came and said that they would take Anato back and provide him with treatment ,Rosé then just nodded and told them to follow him , after the were far enough ,Rosé spoke " They are up to something".They then went and waited next to a lake ,while they were sitting Mitsuki noticed that he was losing feeling in his right arm where he had got cut .

Mugino knows of a doctor nearby, and takes them to see Yubina. She notices Boruto's injury, and painfully grabs his hand, healing it in a show of her skill. Yubina examines Mitsuki, and determines a foreign matter has invaded his system. As Rosé and Sarada have some experience with Medical Ninjutsu, Yubina has her assist in removing the matter from Mitsuki while the others wait outside

She shows them the wood chip she extracted, and reveals it was created with Wood Release. Mugino finds it unlikely that Anato would have Hashirama's cells, but knowing that Hashirama's cells are involved, she connects it to a black market rumour she's heard and the only black market around the area is in the Land of Silence.
