Yomotsu Hirasaka is a blind man who makes use of a tape recorder that he dubs the "Justice" diary, where it records the wrong-doings of future events he thinks need correcting. It's a pretty misleading name since Yomotsu considers the evil deeds committed by a religion cult as much of an injustice as finding random trash on the floor. His diary's actual functions are actually similar to the Sixth's "Thousand League Eyes," but rather it's the "Thousand League Hearing." He is able to create illusions using hypnosis granted by his diary. Yomotsu is quite possibly insane and fancies calling himself a Hero of Justice. He talks using katakana and not the more common hiragana. He defines justice as always being on the side of the winner. He wears spandex along with a toy transformation belt as seen in many super sentai series, as well as a strange one-hole mask which bears similarities to a large eyeball. He is named after Pluto (Hades) —the Roman god of the Afterlife.
