Matsu no Seirei (松の精霊, lit. Pine Spirit), also known as Gajumaru-no-Sei (ガジュマルの精, Chinese banyan sprit), are pine yōkai .
The Matsu no Seirei appears as bald, blue skinned children with half closed eyes and shadows underneath them. They wear short, light yellow yukatas, with a green pine leaf pattern and an orange obi.
Two Matsu no Seirei are a part of the chosen 47 Yōkai Warriors and they represent Aichi Prefecture. They appear in GeGeGe no Kitarō: Nippon Bakuretsu!! Due to the fifth anime adaptation's sudden cancellation at 100 episodes, they are among the 23 Yokai Warriors that were not revealed aside from the movie.
