Description
The Legislator, also known as Rippō, stands as one of the three ruling powers governing the Underworld, alongside Justice and the Executive. His role demands the establishment and enforcement of Underworld laws, granting him authority to issue direct commands to the Master of the Mononokean; defiance risks forfeiting that position.

He manifests as a tall young man with light blue hair and blue eyes. His typical attire consists of a greenish-black haori layered over a matching kimono secured by a blue sash, complemented by dark red earrings and sandals. He is often depicted holding a smoke pipe. His true nature reveals itself as a newt, part of the "Land, Sea, Sky" theme shared among the rulers.

His personality projects a distinctly laid-back and irresponsible air. He habitually procrastinates on duties, frequently leaning on subordinates like Abeno to meet looming deadlines. A perpetual smile masks his emotions, obscuring his genuine feelings. Known as a chain-smoking hedonist, he indulges in alcohol, women, and gambling. Yet, matters concerning his sister Shizuku trigger a sharper, more serious demeanor. He dotes on Shizuku excessively, occasionally misusing his authority to satisfy her whims, and displays a possessiveness others sometimes interpret as romantic affection.

His abilities encompass transformation between human and yōkai forms. He radiates an intimidating aura capable of frightening lesser demons like Fuzzy. As a ruler, he commands the power to compel obedience from the Mononokean's Master.

Key relationships define him:
- With Shizuku, his younger sister and assistant at the Kiyakudo medicine shop, he demonstrates profound loyalty and fierce protectiveness, though she openly chastises his laziness. Their dynamic heavily influences his actions, prioritizing her well-being above all else.
- His relationship with Haruitsuki Abeno remains professional yet strained. Abeno shows minimal overt respect, frequently expressing annoyance at the Legislator's selfish demands for help with neglected work. Despite this friction, the Legislator voices genuine concern for Abeno's tendency to overwork and reminisces warmly about their shared past—Abeno's assistance with paperwork, preparing tea, or offering shoulder massages during his younger days employed under Aoi.
- Regarding Hanae Ashiya, he initially questioned the human's suitability to serve demons but later acknowledged his value as an employee, extending invitations for casual socializing.

His character reveals contradictions: hedonistic irresponsibility clashes with moments of sharp perceptiveness, like instantly identifying Ashiya as human. While often self-indulgent, his fierce dedication to Shizuku and underlying commitment to Underworld governance paint a complex portrait of a multifaceted leader.
