Shikamaru and the others had already noticed earlier, but Sasuke and Naruto were too busy dry heaving, and the girls were too focused on beating up Naruto for anyone to pay attention.
However, Nara Shikamaru thought it was too troublesome, so he'd been lying on his desk pretending to sleep the whole time.
"But! But listen!" Uzumaki Naruto, who'd just become a genin, jumped onto Sasuke's desk once again. "Why is there a Fourth Hokage in the mirror?! Is it a prank?!"
"Nobody but you would pull such a stupid prank!! Super mega idiot!" Sasuke: "And get off my desk!"
"Idiot Sasuke! When have I ever pranked the Fourth Hokage?! At most I just painted poop on his face with paint!!"
Kiba, Shino, Chōji, and others commented from the side—only Naruto could do something like graffiti on the Hokage Rock with paint.
On the Fourth Great Ninja War battlefield—
Learning that the kiss between Sasuke and Naruto was just an accident, the Allied Shinobi Forces finally breathed a sigh of relief. Otherwise, they really wouldn't know how to view Uzumaki Naruto, who was leading them against Madara Uchiha and Obito Uchiha.
But painting poop on the Fourth Hokage's Hokage Rock...
The Allied Shinobi Forces, who didn't yet know the Fourth Hokage was Uzumaki Naruto's father, all thought that terrifying 'Yellow Flash' would be angry. They spontaneously defended Naruto, pleading on his behalf, requesting the Fourth Hokage not to blame him.
Madara: "As expected, an idiot plus a rabble."
"..." Obito: Stupid. Too stupid.
He was certain Naruto wasn't like him as a child at all.
Even when looking at photos of the Minato squad, he'd never forget to tape over Kakashi's face.
Tobirama Senju told Naruto: "Even the enemy is about to laugh at you."
Naruto scratched his head with an embarrassed laugh, internally cringing so hard. Couldn't that Barrage Wall have waited a few dozen more seconds?! Why did it have to show that blunder too?!!
The First Hokage laughed heartily. "Your friendship is really special! Madara and I as children couldn't do what you two did at all! Hahahaha!"
Gotta say, when the First Hokage went dark, he was truly dark.
When he laughed so heartily, nearby Allied Shinobi Forces were all sweating for him, terrified Madara Uchiha would jump over and start fighting right here!
The First Hokage was fine, of course, but wouldn't they ordinary ninja be the ones caught in the crossfire?!
Fortunately, Madara Uchiha was thin-skinned. He glanced in Hashirama's direction and acted like he heard nothing.
Genin Team Assignment timeline—
In the newly formed genin teams' classroom, when Iruka brought in the first jōnin teacher to pick up their subordinates, on the other side of the mirror, Fourth Great Ninja War Minato Namikaze was telling everyone the reason they appeared in the mirror.
"Like the Yamanaka clan's secret techniques, it connects us at different time points." Minato Namikaze: "But all of this may not be the work of ninja."
According to research by Minato Namikaze and Tobirama Senju, this thing called the 'Barrage Wall' was enormous in size and could suppress the Ten-Tails, which could only be contained by the Four Crimson Yang Formation or the First Hokage's Gate of the Great God.
Though they didn't know who wrote those flowing texts from before, based on some of the content, it was clear these texts called 'barrages' were the product of a group of people without chakra casually commenting on the ninja world as after-dinner gossip.
During Minato's explanation, Obito Uchiha, no longer wanting to watch this farce, controlled the Ten-Tails to split off several clones to ambush the Allied Shinobi Forces.
The Allied Shinobi Forces' attention was entirely on the two worlds at the other end of the mirror wall—they didn't notice the Ten-Tails' sudden ambush at all!
Silver and golden flashes of light appeared!
Minato Namikaze, who was explaining to everyone, and Tobirama Senju, occasionally supplementing, had already thrown Flying Thunder God kunai toward the Ten-Tails clones ambushing the Allied Forces!
"Flying Thunder God!" "Flying Thunder God!!"
Rasengan and explosive tags blasted into the two Ten-Tails clones, sending them back to the Ten-Tails' main body in one hit!
"So awesome! Fourth Hokage and Second Hokage old dude!" On the other side of the mirror wall, genin Naruto from the team assignment timeline watched the two Hokage's coordinated battle, his entire being radiating excitement.
Though he felt his excitement was definitely because he saw the Fourth Hokage he'd always admired. "Hahaha, even though I don't understand what you're saying at all, Hokage really are super strong, I'm telling you!!"
From the Fourth Great Ninja War Allied Shinobi Forces' perspective, watching genin Naruto from three or four years ago excitedly talking to them felt like watching TV at home.
Especially since Naruto was so excited seeing the Fourth Hokage that he pressed his whole body against the mirror. The mirror wall as big as the Ten-Tails now only showed Uzumaki Naruto's upper body—they were about to get megalophobia!
Fourth War Naruto was so embarrassed he was jumping around. On the other side of the mirror wall, Iruka and others pulled Naruto back, telling him to move away and not block everyone else's view.
Tobirama Senju: "Just call me Lord Second!"
Who knows if genin Naruto heard or not, because he kept pestering the Fourth on the battlefield, asking what jutsu he'd just used to blast the enemy away and if he could learn it.
Watching the great hero in everyone's hearts, the Fourth Hokage not at all disliking Naruto like other adults did, genin Sakura was very surprised.
To be precise, Lord Fourth not only didn't dislike Naruto like other adults—he actually smiled gently while explaining to Naruto: "This move is called Rasengan. It's a jutsu I haven't fully developed yet. Because in your world I'm already dead, I can't teach you personally. I'm truly sorry, Naruto. But my teacher, Lord Jiraiya, also knows this technique. He'll definitely teach you in the future."
Such an important person, the village's great hero, actually said 'truly sorry' to him.
Uzumaki Naruto, who'd never received such treatment, stood frozen. He scratched his head goofily, wanting to smile and tell the Fourth Hokage it was okay, he didn't need to be so serious, but his nose inexplicably felt very sour—so sour he couldn't even smile naturally anymore...
"Um..."
Another genin in the class quietly raised their hand, asking softly: "Am I the only one wondering why Lord Fourth knows Naruto?"
Uzumaki Naruto never said his name, right?
Why does the Fourth Hokage know Naruto's name, and even promise to have his own master personally teach Naruto the jutsu he developed?!!
Actually, not just Sakura—everyone else noticed too.
When the Fourth Hokage sacrificed himself, Naruto and Sasuke had at most just been born, right?
"Yeah, why does the Fourth Hokage know me?"
