History
In the Buddhist faith, the Four Heavenly Kings are four guardian gods, each of whom watches over one cardinal direction of the world. They reside in the Cāturmahārājika heaven on the lower slopes of Mount Sumeru, which is the lowest of the six worlds of the devas of the Kāmadhātu. They are the protectors of the world and fighters of evil, each able to command a legion of supernatural creatures to protect the Dharma. Zouchouten guards the South.

Devil Survivor
Zouchouten (named Zouchou due to character space limit) is one of the four Devas that protect the barrier between the demon and human worlds. On every ending save for Yuzu's, in order to gain access to the demon world (and thus, Babel) the player's party needs to dismantle the barrier that the Devas protect. After Bishamon's defeat, Zouchou challenges the player's party with Koumoku, planning to make up their lack of power with numbers.

Koumoku and Zouchou are unlocked for fusion after the player defeats them.
