Kabuto Yakushi

Kabuto and Kasumi were comrades, both Orochimaru's henchmen, sent on a rather strange mission: to retrieve a forbidden jutsu that could bring people from the future to the past and vice versa. The mission had been a complete success, and they were already on their way back to base through a misty, humid forest when Kabuto stopped Kasumi, telling her to wait for him with the scroll while he went to the bathroom behind a tree. It's worth noting that at that precise moment, he was 19 and she was 16.

Kabuto was calmly zipping up his pants when he saw a horribly fast and blinding light emanate from the place where he had left Kasumi in charge of the scroll, followed by a muffled scream; he thought the worst and quickly ran towards it, expecting to find enemies.
