Spoiler Alert.PNG Spoiler Alert: WARNING! This page happens to contain a lot of heavy spoilers that are all originated from the Overlord Light Novel series written by the author Kugane Maruyama. To every Anime-only watchers and Manga-only reader out there viewing this warning, please mindfully consider your decision first before choosing to expose yourself on reading the information below.

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.


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.


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 the economy.


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