wait it was so beautiful but I'm a bit confused with the ending... can someone explain it to me?

The kid who had been helping the couple was Judas who betrayed Jesus. The parrot was Jesus so when the kid(Judas) was dying after fighting with the guardians of the judgement tower, he asked Jesus to grant the couples wishes. Angel asked for the demon to become human and demon asked for the angel to be with him.
The Heaven was run by some cherub like beings to keep the world moving calling it the 'God' project but when the real God came into form (dunno what else to call it) He overrode the fake system by completing the mission which was given by him to Judas is a miracle for the couple.

I know a lot of people are gonna be disappointed but well... if it's sucks, move on guys. I too feel like the story is not really great but the art is beautiful :) and I'm sure sensei is working really hard to make this manga ^^ i dont like to talk shit about things unless I'm better at those things
i think there's one page missing. it's not really important but sun jing looked badass in that page
