Terumi Mei: "Hatake Kakashi is a well-known Elite Jōnin in the ninja world. How could he be running out of Chakra here?"
Darui: "Is the famous Copy Ninja of Konoha really this weak?"
Kabuto Yakushi: "The strangest part is, I don't think he's used that much ninjutsu!"
Hatake Kakashi: "..."
Damn it!
Don't any of you run low on Chakra? Why am I the only one?
It's impossible that I'm the only ninja in the world who lacks Chakra!
Orochimaru: "As expected, without Uchiha blood, using the Sharingan rapidly depletes Chakra."
Uchiha Fugaku: "Indeed. For outsiders, the Sharingan cannot be closed, leading to constant Chakra consumption."
Namikaze Minato: "Still... Kakashi's situation is a bit... well, hard to explain."
Minato feels that Kakashi's Chakra capacity at 26 years old might not even match what it was when he was 12.
Summing it up:
Kakashi used the Body Flicker Technique once, Earth Style twice, Water Style once, Raikiri twice, and the Lightning Style stimulation.
Although these techniques do consume a lot of Chakra, for someone as renowned as Kakashi, being this low on Chakra is still a bit embarrassing.
Uzumaki Naruto: "Ms. Kakashi is so weak!"
Back then, after fighting Zabuza for the first time, he passed out immediately!
Sasuke and I had to take turns carrying him...
Uchiha Sasuke: "Indeed."
Uzumaki Kushina: "Too much time reading Make-Out Paradise has weakened his body."
Hatake Kakashi: "..."
Jiraiya: "But Sasuke in that world also reads Make-Out Paradise..."

[Kakashi was panting heavily, staring at Sasuke across from him, feeling a wave of fatigue.]
[Could I really be struggling against a Genin?]
[How embarrassing!]
[If word gets out, I won't be able to show my face in Konoha again!]
[However!]
[Looking at Sasuke, Kakashi didn't see any sign that Sasuke was running low on Chakra.]
["Are you still good on Chakra?" Kakashi asked, unsure.]
[Sasuke, confused by the question, replied, "I'm fine. We can keep going."]
[Sasuke couldn't figure out why Kakashi was breathing so heavily.]
[Maybe that speed-enhancing jutsu has side effects?]
[No matter how he thought about it, Sasuke couldn't imagine that Kakashi had already run out of Chakra.]
[Since the age of seven, Sasuke had been refining Chakra daily alongside his physical training, while leaving the rest of his training to his Shadow Clones.]
[So, Sasuke's Chakra levels were still full, and he was ready to continue fighting Kakashi.]
["Hmm, not bad." Kakashi nodded, the tomoe in his Sharingan spinning slightly.]
["Illusions? They won't work on me."]
[Sasuke immediately noticed the change in his surroundings and realized he was under an illusion.]
[His Three Tomoe Sharingan spun and broke free easily.]
[Seeing this, Kakashi sighed inwardly.]
[Forget it, I can't keep this up.]
[If this goes on, I might need to open the Eight Inner Gates.]
["The test is over. You've passed the assessment." Kakashi announced weakly.]

Uchiha Obito: "??? That's it? Kakashi, keep fighting! Don't be a coward!"
Might Guy: "Kakashi, how can you quit halfway through the battle? It's not over yet!"
Shiranui Genma: "Tsk, I was hoping to see more of Kakashi struggling. How boring."
Hatake Kakashi: "..."
Bunch of psychos!
If I keep fighting, I'll be digging my own grave!
Rock Lee: "Does Mr. Kakashi know the Eight Inner Gates too?"
Might Guy: "Indeed, Kakashi can open the first gate. It would increase his Chakra reserves."
Orochimaru: "Forced to open the Eight Inner Gates, how pitiful."
Jiraiya: "In a bell test, a Genin who just graduated was able to fight evenly with their Jōnin instructor. That's unprecedented in Konoha's history, right?"
Namikaze Minato: "Kakashi did well back in the day, almost getting the bell, but he was nowhere near Kim Sasuke's level."
Jiraiya: "Kakashi's performance was impressive, but Sasuke from that world is even more extraordinary."
---
[Kakashi called over Sakura and Naruto, announcing the end of the test.]
[Sasuke confirmed that he had passed.]
["However, there are still only two bells. Now, as the only one who passed, you can choose your teammate."]
["In other words, you must decide who to kick out, sending them back to the ninja academy."]
["Go ahead, make your choice," Kakashi said with a smile.]
[Sakura and Naruto's faces turned pale instantly.]
["To be in the same class as Sasuke-kun, only to get kicked out? No way!"]
["Damn it! Sasuke passed, but I have to go back to the academy? I refuse!"]
[Both of them were deeply worried.]
[Sasuke held the two bells in his hand and looked at the three of them.]
---
Jiraiya: "Good move. This will test Sasuke's sense of camaraderie!"
Namikaze Minato: "It's an excellent tactic."
Senju Hashirama: "Teaching the younger generation to value their comrades is wonderful!"
Orochimaru: "Ah, to Kim Sasuke, teammates are just meaningless burdens."
Jiraiya: "Orochimaru, you bastard!"
Orochimaru: "Am I wrong? That Sasuke's strategy was to distance himself from Naruto and Sakura to avoid them being captured and used against him."
Jiraiya: "You..."
Hatake Kakashi: "I'm curious to see how the other Sasuke will decide."
I hope this Sasuke has learned to value his companions.
---
[Sasuke looked at Kakashi, narrowing his eyes slightly.]
[After watching for a moment, he noticed something strange—Kakashi seemed to be... out of Chakra?]
[What the hell is going on?]
[This Jōnin is too weak!]
["So, have you made your choice?" Kakashi asked with a smile.]
["I have," Sasuke said, glancing at Sakura and Naruto, then turning to Kakashi. "Why don't you go back to the ninja academy and train for a few more years, Mr. Kakashi?"]
["You can become a guide Jōnin once your body is in better shape."]
["...?"]
[Kakashi was stunned, frozen in place.]
