1. Naruto Uzumaki: *Startled at the impact* Wha-what the... Sasuke!? *Rushes towards the window, wide-eyed with shock* Sakura, did you see that too?! Sasuke just... hit the window! Is he... really dead?! 2. Sakura Haruno: *Initially lost in her thoughts, snaps out of it as she witnesses the event* Naruto! What just happened?! *Gasps and quickly moves towards Naruto* Sasuke... How...?! 3. Sasuke Uchiha (Ghost): *Phantom-like presence appears, looking intangible* Hn... Just passing through, dobe. Don't be a fool, I'm not dead. *Smirks mischievously, disappearing into thin air* 4. Kakashi Hatake: *Raises an eyebrow, witnessing the scene* Well, that's an interesting way to get someone's attention... Naruto, Sakura, what's going on here? I saw Sasuke's ghost? 5. Shikamaru Nara: *Sighs deeply* This is gonna be troublesome... Naruto, Sakura, let's analyze the situation calmly. We can't make assumptions without concrete evidence. Let's figure out what just happened. 6. Hinata Hyuga: *Gasps and covers her mouth with her hands, wide-eyed* N-Naruto-kun! Sasuke... hit the window? B-but... how? Could it be some kind of jutsu? 7. Ino Yamanaka: *Approaches the shattered window, confused* Wow, Sasuke really knows how to make an entrance, even in the afterlife! But seriously, what's happening? Is he actually dead, or is this another one of his ploys? 8. Rock Lee: *Eyes shining with determination* Fear not, my youthful friends! I shall investigate this occurrence and uncover the truth! Is Sasuke truly departed, or are we witnessing an incredible illusion?! 9. Tsunade: *Raises an eyebrow, skeptical* Hm, an unusual turn of events. Naruto, keep calm until we determine what really happened. Sakura, I want you to assist Naruto in investigating this matter. We need to be sure before jumping to conclusions. 10. Itachi Uchiha: *Appears, seemingly aware of everything* Sasuke, hitting the window? How humorous. Relax, Naruto, it's just an illusion created by a jutsu. Sasuke isn't dead, nor is he here. Remain focused on the task at hand. Note: These reactions are based on the personalities and previous interactions of the characters in Naruto.
