Master & servant - v. 2 : Master and Servant

We slowly learn about the world that Chigusa and Narushige are from, how during a dark time when it seemed like the world was ending, a young boy arrived out of nowhere, claiming he was the child of God.

No one could hear his voice except one boy, Kinrei, who was called upon to be his 'servant'.

Back in Rakan's world, Chigusa and Narushige discover evidence of another person that has crossed over.

Could it be this child?
