Ecrin

Ecrin (えくりん Ekurin) is one of most prosperous cities of the Kingdom of Bosco. It is considered to be the pride and glory of Bosco to be where the infamous House of Royard resided during their time as nobility as well as St. Bahram's Imperial Military Academy, the army's training institution.

Ecrin also houses the kingdom's most powerful military asset asset, the Daeva division.

Overview
Despite not being the capital, Ecrin is the largest and most populated city in the Kingdom of Bosco. It contains a population of 8 million people- nearly 1/4th of the entire kingdom's population.

In contrast to Bosco's military doctrine, the city is the headquarters to the elite combat division Daeva and the premier training facility of St. Bahram's Imperial Military Academy- the kingdom's top academy for the army.
