ECLAIR is obsessed with cleaning and has great pride in being the assistant butler of the Great Tomb of Nazarick to the point of arrogance. Carrying himself with an enormous ego of self-worth, one of his greatest desires is to sit upon the throne of Nazarick. Though Eclair understands this act is treasonous to the Forty-One Supreme Beings and likely due to him also understanding that his creator specifically made him to be this way, he still respects them highly. Eclair is a penguin.
