NOTE (if you missed it the first time around): I've made a vital error…I've been accidentally calling the member from Team 8 a member from Team 10, throwing off the entire answer. Gah! I'm very sorry about this! I have fixed it all. THANK YOU Kakashigurl20 for making me realize my mistake.

And yes, the Ichiraku owner's name is Teuchi. I got it from Leaf Ninja dot com, a site that has all the Naruto info I can ever need. lol

ANSWER: KIBA blew up ICHIRAKU RAMEN with his KUCHIYOSE NO JUTSU. His summon was carrying the EXPLODING NOTE. The person standing next to the tree was HINATA, and her SHURIKEN was aimed at SASUKE.

I would have also taken the answer if you didn't mention that Kiba's summon was carrying the exploding note.

Congratulations for solving this mystery goes to: roszchan, Kakashigurl20 (after you changed your answer to Hinata)

In the beginning, we know that Sakura was the girl twirling the kunai around because she had her double personality and her love for Sasuke. She left shortly after so she had no motive for committing the crime. After Kiba came in, the person from his team had to be Hinata; there is a vague clue in where she takes a seat next to Naruto rather than Kiba, but there are stronger clues given later on that the person is indeed Hinata. Later, after Kiba had left, a BOY came in and took a seat next to Hinata. And a few minutes later, Naruto jumps up and challenges "stupid" to a spar. "Stupid" must be Sasuke, because of their interesting rivalry, leaving the boy left in Ichiraku to be Shino. We can also deduct that it is Shino because he dislikes loud people like Naruto, and he sits next to Hinata. Another reason that the person from Team 8 must be Hinata is because she became frustrated after Naruto left, and got up shortly after he did.

Later that night, Hinata is the one standing next to the tree because she is finally referred to as a "she". The dark thing she saw running from the corner of her eye had to be Kiba's summon, the black cat. It couldn't very well be Shino's giant roach because a giant roach would certainly not be stealthy enough to avoid Hinata's eye. After she saw Kiba's summon, she saw something ELSE out of her other eye, and she got frustrated at it, and threw her Shuriken at it. It couldn't have been Kiba's cat again, because she saw something ELSE. But what could have Hinata so frustrated that she'd throw a Shuriken at it?

Sasuke. The Shuriken was aimed at Sasuke because he was the reason why Naruto left Hinata's side earlier in the ramen shop.

Kiba's cat was carrying the Exploding Note, which we knew he had because of the crumpling in his pockets. The cat set it in the Ichiraku, and quickly ran for cover. Kiba couldn't have just waltzed in and set the note himself, because there was no indication that the store was closed. In fact, the Ichiraku is usually seen to be open at night. And he couldn't have asked Akamaru to do it because the two are inseparable, and it would have been obvious.

Fortunately for Teuchi, he smelled something burning right away. After checking it wasn't his ramen, he turned and noticed the Exploding Note. He quickly ducked out of the ramen shop a split second before it blew up.

Sasuke, on the other hand, was fine as well. In fact, he was so surprised by the random Shuriken flying at him that, after he took a moment to recover, he wildly gazed around looking for his attacker, not even sensing who it was. Unfortunately for him, Hinata had run away after the explosion at the Ichiraku, and during the explosion, he quickly forgot about the whole ordeal and his only "injury" was a scratch.

Even more unfortunately for him, since he was standing near the Ichiraku at the scene of the crime, he was accused of blowing it up. But fortunately for him, Teuchi, who saw a suspicious looking black tail walk out of his shop, told the Godaime about it. She automatically pointed her finger at Kiba, who gave her a guilty look. Kiba's sister, who heard about his day at the ramen shop, shook her head in disappointment.

But the most disappointed of all was Naruto. Even when Kiba was assigned to build and help maintain a new Ichiraku shop, Naruto glared at him for months after.

The Second Mystery: More Cheese, Please!
