Benjiro spoke out from the shadows, cloaked in his ANBU ensemble. Orochimaru apparently didn't notice him...which meant he was good enough at keeping hidden to deserve his rank as ANBU Captain.
"He has been properly kept under tight lock and key, and multiple seals designed to keep him from utilizing his little Kitsune friend." he informed his Kage with a nod, stepping from the shadows to reveal himself. If not anything, Orochimaru would be able to recognize him by voice, as he no longer masked it.
"My lord, have you anything in need of my services? If no, I should like to take leave...I've been couped up in here as long as the kid has." he requested. He knew that two more of his students had passed the chuunin exams...he wished to congratulate the pair, even though he hadn't really been there for them as much as he should have; between ANBU and medical duties, paperwork and hard work often piled up before he had the chance to train his students.
