1 Angry Ghost Panti & Sutokkingu with Gâtâberuto : Season 1 Episode 15

The disguised Demon sisters put Panty and Stocking on trial for the murder of a friendly Ghost, with a monkey wearing a translation device on its head serving as the sisters' defense attorney. The sisters are found guilty and sentenced to electrocution, which jolts the monkey lawyer's translation device and grants him heightened intelligence, allowing him to prove the sisters' innocence and implicate the murdered Ghost's wife as the true culprit.
