Rippō is a tall young man with light blue hair and blue eyes. He dons on a greenish-black haori over a greenish-black and red kimono with a blue sash and sandals. He wears dark red earrings and is mostly seen with a smoke pipe. He usually has a smile on his face.
He has a rather laid-back character despite being one of the top three most influential yōkai in the Underworld that manage the governing of the Underworld. He tends to smile a lot to mask his actual expression and feelings towards certain situations, so that one would find it difficult to note whether he is pleased or annoyed. He enjoys drinking and loves women. He seems to get sulky when Haruitsuki did not inform him of hiring Hanae. He also gets worried about Haruitsuki easily as he works too hard. He seems to be rather lazy as he puts off his work until the deadline and asks Haruitsuki to help out in Chapter 26. Apparently, Haruitsuki describes him as a chain-smoking and alcoholic sex maniac who loves gambling in Chapter 11. Haruitsuki also said that he can also party and drink for 10 hours. He is also quite sharp as he noticed that Hanae is human when he first met him. He tends to dote on his little sister and he becomes serious when it concerns his little sister. Haruitsuki states that Rippō is in love with his own little sister.
As the Legislator, he makes the laws of the Underworld and is able to directly give orders to the Master of the Mononokean.
Rippō can transform into a human form.
Fuzzy seems to be afraid of Rippō when he first met him that Fuzzy cowered in fear and hid behind Hanae.
Haruitsuki is his employee, however, Haruitsuki does not seem to respect him much. Haruitsuki does not even bother to hide his anger towards Rippō when he asks for his help in doing his work in Chapter 26. Haruitsuki will even grab Rippō's injured right arm tightly to check whether he was really injured. He gets annoyed when Rippō acts selfishly, as seen in Chapter 11. Rippō is also overly worried about Haruitsuki working himself to death. Even so, they seem to be on good terms. In chapter 63, Rippō reminisces about the time he was fond of Abeno when he was a young employee of the Mononokean, who helped him sort his papers, and when Rippō was tired Abeno would prepare him tea and massage his shoulders.
Shizuku is Rippō's little sister. Rippō tends to dotes on his little sister and even abuses his authority to get what she wants in a rather comedic way. He feels lonely without her even though she had visited him the day before. However, Shizuku does not hesitate to scold her brother when he puts off his work till the last minute. He also becomes serious when it concerns his sister. Haruitsuki stated that Rippō is in love with his sister.
