Hakka

Hakka is the new President of the Ferrymen River Department in WFO. His personality slightly resembles that of Bekko's and Chika's father: he is sometimes serious, cool and mysterious, but at most other times he can be simply gay-like. He shows a rather sickening admiration and friendliness towards Bekko whom he calls "Bekko-chan", even feeling jealous of him because he has a 'nicer ass'. Motivated by Bekko's efforts in the Z-Loan office, he too sets up a loan company called A-Loan (Alive-Loan) and employs the trio Zen, Toko and Shuji. In actual fact, he is also the President of the ARRC (Akashic Record Reform Committee) and his real aim for creating A-Loan is to get rid of Z-Loan.

He seems to know a lot more about the backgrounds and history of others such as Shiba and Michiru. In Volume 10 of the manga he reveals to Michiru that she is a Singularity and not a human. (source:Wiki)
