Masaki Makabe is a supporting character in the anime Zettai Shounen, also known as Absolute Boy. He is a teenage boy with short brown hair and green eyes. Makabe is introduced in the second half of the series, which shifts the setting from the rural town of Tana to the city of Yokohama. His nickname among friends is Makki.

Makabe is often seen playing games on his mobile phone, suggesting a casual and somewhat tech-savvy personality. He becomes involved in the story when he starts assisting the reporter Akira Sukawara with her investigation into mysterious phenomena known as material fairies and material evils, supplying her with valuable information. His motivation for helping appears to be partly driven by his apparent crush on Rieko Yamato, a young woman who also becomes connected to the events. This interest in Rieko gives him a personal stake in the unfolding mystery.

In terms of role, Makabe serves as an information source and a local contact for Akira in the Yokohama arc. He does not possess any special abilities or direct involvement with the supernatural elements of the story; instead, he represents an ordinary person drawn into the strange occurrences through his connections and curiosity. His character does not undergo significant development over the course of the series, remaining a helpful and friendly presence who provides support to the main characters.
