In this castle, there’s a main in-charge Technician– the most senior at 76 years old– and everyone else there just calls him Boss, because he is the first Piu to maintain Mea’s first dreams, and that he looks like the highlighter that Mea first discovered that happened to be of Boss brand. He is the technician in charge of maintaining the first four storeys of the castle (dreams Mea had at the age of four), and the pantry behind the navy-coloured door. He also overlooks all the dreams in the castle.

Followed by the Boss, there are two other technicians who are Boss’s sidekicks, also of high seniority; one maintaining dreams from the fifth to eighth storeys, and the other maintaining the ninth to twelfth storeys. The former is named Pen (72 years old), and the latter named Glasses (68 years old).

Pen and Glasses take care of the welfare of their fellow co-workers, and take turns to organise gatherings at the pantry, mostly work meetings and sometimes parties.

The remaining technicians have other roles like also maintaining the facilities of the castle and its cleanliness. The remaining ones just do their jobs of maintaining their storeys.

P.S.You probably know how the rest of the technicians are named now, but just in case: by the most significant object that Mea got introduced to in those four-year periods, and by their appearance. (The Pius all look similar initially, but their appearance is later shaped by the significant objects. They keep changing until they reach the highest storey of their purview)
