Hyakkiyako Intro

Hyakkiyako's Logo

Hyakkiyako Alliance Academy (百鬼夜行連合学院) or Allied Hyakkiyako Academy on Global, is one of the many schools in Kivotos.

Background[]

// FILE.013 [Hyakkiyako Alliance Academy]

Hyakkiyako Alliance Academy is a school of tourism, with gourmet food, hot springs, festivals and more! The academy is a coalition of clubs and committees, each with their own rules and regulations, so there is no formal student council.

General[]

One of the schools in Kivotos, which unlike the others is simply more of a "coalition" of clubs of committees with their own respective rules and policies. Their main industry is tourism and is applied in a variety of activities, with the largest activities dubbed as "Festivals".

Due to the structure of Hyakkiyako, there is no formal student council in Hyakkiyako, though the Yin-Yang Club is sometimes seen as its de-facto student council.

Historically, Hyakkiyako was in a similar state to pre-alliance Trinity, where factions fought against one another in what was known as the age of the warring districts. According to a tale, the Great Prophet Kuzunoha established the Hyakkaryouran Conflict Resolution Council as a way to mediate conflicts between factions.
