Takeyuki Kiuchi is a former baseball player who lost his career after an incident and became a salesman. He is the first target of the Phantom Thieves of Desires, as his actions cause people around him to lose hope in the world, leading to incidents such as Manaka Nagao's attempted suicide. Upon becoming a Menace, Kiuchi is a vengeful, arrogant and lustful man who has a reputation as a womanizer, and is known to attack and harass women at train stations. When Kiuchi was a baseball player, he was known to be rather arrogant, and would proudly believe he did not have to practice, claiming he was already a great baseball player through natural talent. Kiuchi also seems rather unscrupulous and callous, showing indifference towards the harm and the pain he causes women at the train station, shown by his response after he pushed Tomoko onto the train tracks while trying to attack Motoha. At the peak of his rampage, he appears to be entirely unrepentant, and mocks Motoha's intention to get him arrested.

Voice Description: Medium-low male vocal range. A womaniser in and out, every word Kiuchi states should carry an element of venom and arrogance to it.
