Especially ninja like Shōji, who possessed a Kekkei Genkai.
As long as they used their Kekkei Genkai during a mission, their identity could practically be pinned down. The Nara, Inuzuka Clan, Aburame, Akimichi, and other Ninja Clans were all like this. Still, quite a few of them had joined the Anbu. Without further intelligence, others could at most identify their clan, but it would be difficult to determine their true identity.
Shōji alone was different. The moment he used the Sharingan, it would be far too obvious. Thus, whenever he went on missions with others, his identity would inevitably become known to his teammates. This also applied to the squad captain he was currently following. If this Zero truly was Kakashi Hatake, then there would definitely be a chance that he would use the Sharingan and the Lightning Cutter during a mission.
Once those two ninjutsu and dojutsu were used.
His identity would be ridiculously easy to guess.
This was a targeted investigation.
Therefore, Zero had merely said it, and Shōji had merely heard it. After all, they both knew the truth. Trying to ensure one's identity remained one hundred percent secret was simply impossible.
Zero knew that as well.
After saying that, he did not continue speaking.
He led Shōji deeper down the passage on the left, until they arrived before a pitch-black iron door.
Zero gently pushed open the door and led Shōji inside.
Five figures were already waiting within. The instant they saw Zero arrive, the previously lax-looking group immediately changed their demeanor. Each of them straightened up and faced Zero directly.
"Squad Captain!"
They all gave slight bows, showing the basic respect due to their squad captain.
Then Shōji met the gazes of the five colleagues, all dressed in standard Anbu uniforms and varying in height.
