Miboshi is a member of the Seiryuu Seven, celestial warriors sworn to protect the Priestess of Seiryuu from harm. Though small in size, Miboshi is actually a very formidable opponent. In addition to his mastery of black magic, Miboshi can levitate in the air, and also has the ability to summon demons to his aid, something that makes him very dangerous indeed. As a member of the Seiryuu Seven, Miboshi is loyal to Yui and Nakago and will do anything to prevent the summoning of Suzaku and impede the Suzaku Seven.

Miaka and the others encounter Miboshi in a tower as they try to prevent the summoning of Seiryuu from happening. Miboshi blocks the way up to the upper floors of the tower and summons demons and uses his magic to attack the group. However, Tatara, one of the members of the Byakko Seven who was guarding the tower, is able to fight with Miboshi, using his power over vines and seeds to stop Miboshi's attempts to kill the Suzaku Seven.

It is eventually found that Miboshi lost his physical body a long time ago in his study of black magic, and in order to extend his life span has taken possession of a number of bodies (especially those of children, due to their susceptibility). Even though he was eventually defeated, he definitely pushed the Suzaku Seven to their limit, not leaving them out of the battle unscathed.
