Panasolei Gruze Day Rettenmaier

Panasolei Gruze Day Rettenmaier (パナソレイ・グルーゼ・デイ・レッテンマイア) was the mayor of E-Rantel until the city was ceded over to the Sorcerer Kingdom. He is a noble of the royalty faction of the Re-Estize Kingdom.

Appearance
He is described as a mass of bloated, fatty oil, so much so that even his chin consists of excessive fat. His face resembles that of an unremarkable obese bulldog. The white hair on his scalp is thin enough to reflect light.

Personality
Panasolei sometimes breathes like a pig (プヒープヒー = onomatopoeia), which lowers his overall impression as untrustworthy at first glance but he is in fact, a very clever man. His behavior aims to make others to look down on him so that he can catch them off guard.

Unlike many nobles, he doesn't look down on commoners and actually cares for them. He is also hardworking, taking a large amount of time to get accurate statistics to help forecast future trends in economy.

Background
A noble and a member of the Royalty Faction. Due to his fair temperance towards commoners, he was precisely posted to E-Rantel.

The Bloody Valkyrie Arc

The Magic Caster of Destroy Arc
When King Ramposa III and the Royal Army stayed in E-Rantel to prepare for the annual war against the Baharuth Empire and Nazarick, Panasolei gave his report of the domestic state of the Kingdom. His report revealed that the Kingdom was steeping further into economic decline and would not survive another war.

The Ruler of Conspiracy Arc
The mayor along with all the other bureaucrats and officials who had previously been responsible for managing the city have fled to other lands controlled by the Re-Estize Kingdom after the Sorcerer Kingdom of Nazarick took control of the city. Ainz Ooal Gown took up residence in the mayor's former residence and remodeled it into Ainz's own chambers.''
