Jinsoku's past is currently unknown. However, he stated that his background is "boring and repetitive".
Jinsoku is a calm, logical young man which only believe what his eyes tell him. He is relatively cold with the Ninja under his command, and wishes to be treated very respectfully. Despite this behaviour, he seems to be very confident in his abilities, and never seems scared by an opponent.

However, he stated that he did not posess any Dojutsu, saying that his current powers are sufficient to defeat any one in his path. Jinsoku always wear the Iwagakure flak jacket over a black shirt.
