Hikage

The Seizakage (星座影, Lit: meaning Constellation shadow) is the leader of Entenkagakure and is typically the strongest shinobi in the whole village.

Like other ninja villages, the new Seizakage is elected by the old Seizakage once he retires. If the old one was to die or be incapacitated before choosing his successor, the Solar Elders would appoint a shinobi as the Seizakage. Afterwards, the candidate will need to be approved by the jōnin of the village to become the official Seizakage.
