Her sensei, Kurenai

Hinata never told anyone but she sort of admired her sensei, Kurenai. She was tall, cool headed, and very kind. She was almost like an older sister for Hinata. Next to Naruto, she was one person she would never mind becoming. How convenient that there she was, scrubbing her hair in a bath right across from the pair. Now was the perfect time to deflate her.

"H-how about Kurenai-sensei?" asked Hinata.

"Sure! This could be interesting. Wait here okay?"

Naruto got up out of the bath and casually entered the one Kurenai was in, she didn't seem to take notice however. With the air tank underwater, Naruto swam slowly towards the black haired woman. His head was covered in bubbles as camouflage. When he finally was in reach of her, waited and then quickly grabbed her around the neck with his arm and pulled her underwater! The other women in the bath took it as simple playing and didn't bother noticing. Under the soap bubbles however, Kurenai was kicking madly. Naruto quickly shoved the tank into her mouth.

Kurenai thought she was being ambushed by an enemy ninja. Her attacker had put something cold and metallic to her mouth and it was draining the air out of her. They were trying to drown her, or so she thought. She felt smaller somehow, lifeless in a way as the device in her mouth drained her completely. But she wasn't feeling the normal burning feeling in her lungs as one would normally would when losing air. She felt hollow and empty, like the metal thing was draining her life essence as well as her air. She was starting to lose consciousness. Desperately she turned to get a final glimpse of her assassin under the soapy waters. The last thing she saw was pink hair and a foolish grin.

"Gotcha, sorry about this Kurenai-sensei." Naruto mouthed out.

He emerged from the depths and placed the air tank on the side of the bath. Then he waited until any wary eyes had turned away before quickly pulling out the new Kurenai suit and hiding it under a towel. He stood up and returned to Hinata, who had been watching the whole scene with deep interest. Naruto tossed her the air tank and said.

"Come on, let's head to the locker room so you can change."
