You were the Jinchūriki of Ichibi. Ichibi is also known as Shukaku. It passed 11 years since the Kazekage sealed Shukaku inside you, you often could hear Shukaku's monster-like voice.
11 years after Kazekage sealing Shukaku inside you. You were battling the Ninja Genins of your village rivals, which you got humiliated after your awful defeat. You feel really angry and thirsty for revenge, Nothing but Shukaku's chakra made you to go on your own subconsciousness. You saw a cage, labeled "Seal (封)". The realm was filled with sand, which it probably was from Shukaku's. Surprisingly, you saw him inside the cage, staring down at you with his yellow eyes. Shukaku was in alot of anger and hate, as usual. He now spoke, with his monstrous-like voice.
"You need to kill them all... Why aren't you doing so?! Are you really this weak now?"
Shukaku yelled now. His voice was now a deep demonic voice.
"YOU MUST KILL, REVENGE ALL THE HUMANS. MAKE THEM KNOW WHO'S THE REAL DEAL."
