"Minato-sensei!"
Kakashi's voice trembled a little. He had not expected Minato to appear at this moment either.
"Well, I couldn't help it. Naruto's already made that big promise, after all."
Minato scratched his head and spoke a little sheepishly.
"Kakashi, I'll vouch for what Naruto promised too. Just tell Lord Third that when you get back."
Kakashi nodded, then asked curiously, "Sensei, your current form..."

"No wonder Naruto knows so many ninjutsu. Thank you for all your hard work, Minato-sensei."
Kakashi scratched his hair and spoke in a relaxed tone.
"Huh? Wait,
