He has dark marking around his eyes and wears the standard Iwagakure flack jacket, without a shirt underneath, but still wears the traditional pants and lapel, with sandals. He also wears bandages around his arms.

As the three brothers surround Kosuke plotting to interrogate him for intelligence on Konohagakure, they are thwarted by Team Asuma and their Formation Ino–Shika–Chō.
