(This is a parody plot about changes to the future. It doesn't affect the main story. While writing it, I've also considered the point in time the story will reach later in Boruto.)
The exam had ended, and everyone now had a sense of Bai Lin and Tsunade's strength. They couldn't help marveling that they really were students of the Third Hokage.
Kushina hurried over to Bai Lin to check on him. Her red hair swayed anxiously as she reached out to help, then hesitated, afraid of touching his wounds. Her eyes were red-rimmed. "Brother Lin! Are you all right? You're bleeding so much!"
She pulled some medicine from her ninja pouch and clumsily but earnestly tried to bandage him. "Lady Tsunade is so mean! I hate her the most!"
Tsunade: ???
Tsunade had been about to leave, but when she heard Kushina complain, her expression darkened again.
"Kushina, this brat is no good. Don't get close to him again."
Tsunade grabbed Kushina by the collar and lifted her off the ground. Kushina kicked wildly, her red hair bristling with anger. "Let go of me! You're the mean one, Lady Tsunade! You beat Brother Lin up like this. I'll never forgive you!"
"Forgive me?" Tsunade gave Bai Lin a hostile look.
"Kushina, don't say that. Lady Tsunade only did it for my own good!" Bai Lin gave an awkward, guilty smile.
"Hmph!" Tsunade snorted and let go. Kushina stumbled over to Bai Lin, not forgetting to glare back at Tsunade.
Tsunade watched the two of them stand together against her and ground her teeth in anger.
Just as everyone was preparing to leave, something unexpected happened.
"What an interesting scene. I never expected to see such a good show as soon as I arrived."
A cheerful voice came from behind a tree not far from the clearing. The people in charge immediately grew wary and looked toward the sound.
Someone had been hiding nearby for so long, and they hadn't noticed at all.
"Utatane Koharu, Mitokado Homura, organize the children and get them out of here at once. The newcomer means trouble." Hiruzen Sarutobi quickly assessed the situation and immediately gave the order.
The students still had no idea what was going on, and their faces were full of confusion.
Utatane Koharu and Mitokado Homura immediately sprang into action. They reassured the students as they quickly organized them to evacuate toward the edge of the training ground. "Everyone, don't panic. Follow us, quickly!"
The person behind the tree slowly stepped out, and everyone turned to look.
The newcomer had pale skin and light blue hair tied in a high ponytail. Two dots marked his forehead, and two horns shaped like Forehead Protectors grew from his head.
He wore white robes and carried a red-glowing fishing creel, with a red-glowing fishing rod in his hand.
"Otsutsuki Urashiki!"
The moment Bai Lin saw the newcomer's face, he had a bad feeling. The course of reality had completely slipped out of his control!
"Byakugan?" Everyone turned to look at Hyuga Tenin, the head of the Hyuga Clan.
Hyuga Tenin was completely stunned. He didn't want anyone thinking the Hyuga Clan was plotting something and putting them in the same position as the Uchiha Clan, so he hurriedly replied, "Lord Hokage, I don't know him. Don't frame me!"
"Who are you? Why are you in our Konoha? Are you from Amegakure, Sunagakure, or another hidden village? Why do you have the Byakugan?" Hiruzen Sarutobi nodded. His hands rapidly formed seals, Chakra surging around him as he warily watched the newcomer.
He had never seen such strange attire. The Chakra radiating from the man belonged to none of the hidden villages of the Five Great Nations, yet it carried a suffocating pressure far beyond that of an ordinary Kage Level ninja.
He had never sensed such oppressive power from anyone, not even his teacher, Senju Tobirama.
A playful smile curled Otsutsuki Urashiki's lips. His light blue eyes swept over everyone present before finally settling on Tsunade and Kushina.
"The ninjas of Konoha are more interesting than I expected. As for who I am..."
He lifted the red-glowing fishing rod and swung it. An invisible Chakra Thread shot toward a nearby tree and pierced straight through its trunk. "You can call me Otsutsuki Urashiki. I came to Konoha for two reasons: first, to get the Nine-Tails Chakra; second, to kill a few people."
Bai Lin felt like his head was about to split. He was the only one who knew that Otsutsuki Urashiki absolutely should not have been here at this point in time.
Since Urashiki had made it here, it was almost certain he had used the time-traveling artifact, Plow.
"Wasn't the future supposed to be unaffected?"
"Damn it, does it have to be this bad?" Bai Lin hurriedly pulled Kushina along as he slowly retreated behind the others.
(In Boruto, Urashiki never cared about whether he might affect the future, which completely contradicts the original setup for Plow. For example, he unsealed the seal inside Naruto.)
Minato Namikaze had already left with the students. Aside from Bai Lin and Kushina, who refused to leave his side, only Konoha's top fighters remained.
"Nine-Tails Chakra? Killing a few people?" Hiruzen Sarutobi's pupils contracted. He immediately realized that the newcomer's target was Mito Uzumaki. "Otsutsuki Urashiki... I've never heard that name! If you want to lay a hand on anyone in Konoha, you'll have to get past me first!"
"You've certainly got nerve, showing up here alone. Even the Kage of the Five Great Nations wouldn't dare face the Konoha Ninja by themselves." Shimura Danzō made sure everyone noticed him. After all, he was going to be Hokage someday. He couldn't let Hiruzen Sarutobi have all the glory.
Everyone took up fighting stances. The newcomer had clearly come with hostile intentions and must have been confident in his overwhelming strength to appear before them.
"Hehehe!"
Otsutsuki Urashiki rose into the air and looked down at the people of Konoha with disdain. "Konoha is nothing but a bunch of ants."
Hiruzen Sarutobi watched Otsutsuki Urashiki rise into the air and was startled. "Everyone, he seems to be an Iwagakure ninja. He knows Earth Release: Light-Weight Rock Technique."
Earth Release: Light-Weight Rock Technique was the Third Tsuchikage's signature technique. It reduced the user's weight, allowing them to stay airborne for extended periods and giving them both mobility and a tactical advantage.
In the Ninja World, where people couldn't fly, few techniques could be used for aerial combat. That made them assume the newcomer was an enemy from Iwagakure.
"Ants? What a big mouth!" Shimura Danzō snorted, formed Hand Seals, and charged at Urashiki. "Let me show you what Konoha can do!"
"Wind Release: Vacuum Sphere."
"Pathetic trick." A sneer curled Urashiki's lips. He calmly leaned to one side, dodging the air bullets that shot toward him like actual bullets.
He swung his red-glowing fishing rod, and a Chakra Thread shot out.
Before Shimura Danzō could react, the thread pierced through his body.
"What's this?" Shimura Danzō felt no pain. He laughed. "Is that all?"
As Otsutsuki Urashiki pulled the thread back, a ball of blue Chakra was drawn out of Danzō's body.
"Ah, my Chakra!" Shimura Danzō screamed.
"Danzō!" Hiruzen Sarutobi's expression changed dramatically. He formed Hand Seals. "Fire Release: Fire Dragon Flame Bullet!"
A huge fireball roared toward Urashiki.
At that moment, Hatake Sakumo reached Shimura Danzō, grabbed him by the clothes, and brought him back to the others.
Everyone unleashed their ninjutsu at Otsutsuki Urashiki.
Every incoming technique struck Otsutsuki Urashiki without fail. Just as everyone thought they had defeated him, he appeared near Hiruzen Sarutobi.
"Hehehe, all that effort for nothing." Urashiki's laughter rang out, dripping with contempt.
A ball of dark Chakra appeared in his hand, and he hurled it toward Hiruzen Sarutobi.
"Earth Release: Earth-Style Wall!"
Hiruzen Sarutobi's expression changed dramatically as he hastily performed the technique.
A thick earthen wall erupted from the ground. The dark Chakra slammed into it, and the figure quickly retreated.
"Lord Hokage, all the Chakra in Lord Danzō's body has disappeared. This man can use the fishing rod in his hand to extract all the Chakra from someone's body." Hatake Sakumo immediately shared what he had learned with everyone.
"What? What kind of ninjutsu is that?" Everyone was shocked.
