Suiren

is a kunoichi from Amegakure and a teammate of Ajisai.

Naruto's Back: Friends' Tracks
Some time after Nagato took control of Amegakure, Suiren and her teammates were sent to Konohagakure to join an early Chūnin Exam co-sponsored by Sunagakure. There, Suiren and her teammates were randomly split up and sent to different rooms to take the written test. The proctor Shikamaru Nara explained that everyone only needs to answer one question on the test but their combined score with their teammates will determine if they pass or fail the exam as they need exactly 100 points to pass. As her teammates knew of her Sensor-abilities, they signaled with their fingers what question they would each take.

Abilities
