Koichi snuck into the villiage hidden in the leaves. Some anbu were pratoling around the gates after the recent jail break so Koichi had to be extra careful.
Koichi snuck around and came to the Hokage office late at night after the Kage left for the day after all the missions were assigned. Koichi snuck up in through the window when no anbu were listening or watching and no ninja would see him in the building. Koichi snuck around and whenever any ninja got here ducked under the Hokage's desk. "this should help pencil jutsu" Koichi darkened himself to be the exact color and darkness as his surroundings. A chunin walked into the room to tell the Hokage he had completed a mission and Koichi hid in the shadows by the door. Koichi got in front of the door and the chunin didn't notice. The chunin was just turning back to leave when Koichi jumped out and held his hands with 1 of his large hands.(to stop jutsu) and the other over the chunin's mouth to stop him from screaming.
" who is in possession of the nijju in the hidden leaf villiage. If you scream when i give you a chance to speak you will die,if you try to bite me you will die,if i find that this meeting was ever told to anyone you will die."Koichi said in a whisper. The chunin nodded with fear in his eyes. Koichi took his hand off and the chunin responed loudly.
"the Hokage" The chunin yelled out. Koichi didn't have time to stay for specifics but He used eraser jutsu on the door making it non existant so the only exit or entrace was the high window. Koichi through the chunin against the wall and stabbed his heart. He died fast Koichi took the papers regarding the nijju on the Hokage's desk and returned to the akatsuki headquarters.
