Why didn't Hiruzen just say that the prosecutor made a mistake and did not correctly count the number of clones? And this rat is not ashamed of his accusation? He offended a war hero and a strong Shinobi. He's just a lubricant for kunai, now he has to tremble with fear at night

Mc fought Rasa for killing Pakura
