"There's always a paradise that needs to be built. That vow is like the sun in the sky — perhaps I'll melt and fall before reaching it... But some hardships I must endure."[9]
Sunday is a playable character in Honkai: Star Rail.
The dream of the Order has dissipated, yet there are still those who will not give up on their original intent.
— The traveler whose wings were clipped... whereto shall his footsteps lead?[9]
He was temporarily an Emanator of Harmony after usurping the Harmonious Choir.[2]
