Munemitsu Makurazaki is a supporting character in the anime and manga series First Love Monster. He is an adult male with light purple hair that is cut to neck length and blue eyes, and he typically wears glasses. His occupation is that of a butler, and he is employed in the household of the Takahashi family, specifically serving as a dedicated personal attendant to Kazuo Noguchi.

Makurazaki's most defining trait is his intense and almost obsessive devotion to Kazuo. He takes his role as a butler far beyond standard professional duties, often displaying an exaggerated, single-minded focus on serving, protecting, and being near Kazuo. This devotion manifests in behavior that borders on unhealthy, as he frequently goes to extreme lengths to ensure Kazuo's comfort and to eliminate any perceived threats or inconveniences. His loyalty is unflinching, but it often carries a comically extreme and possessive edge that contributes to the series' absurdist humor.

In the story, Makurazaki functions as part of the eccentric ensemble surrounding the main cast. His presence primarily serves to support and interact with Kazuo, and through these interactions, he highlights the quirks of the other characters. He rarely interacts directly with the main romantic storyline between Kaho Nikaido and Kanade Takahashi, instead remaining in the background as a fixture of the Takahashi household. His motivations are simple and unwavering: he exists to serve Kazuo, and any action he takes is driven by that singular purpose.

Makurazaki does not undergo significant character development over the course of the series. His personality remains consistently exaggerated and dedicated throughout, providing a stable comic relief element. Notable abilities include his proficiency in domestic and service-related tasks, as well as a sharp awareness of Kazuo's needs and moods. He is not portrayed as a fighter or as having any supernatural talents; his skills lie entirely in his role as a butler.
