Yokumiru Mera is a worker for the Hero Public Safety Commission. Yokumiru suffers from sleep deprivation due to overwork, something that he complains about frequently. This translates to a blasé and unenthusiastic personality when he's working. He was shown to be very disinterested. However, he can also be quite inspirational at times, such as when he gave a speech about the next generation of heroes having to take the mantle from their superiors.
