Shitty writing and summary I just saw on wiki
>Mel opens her eyes to find herself in the city's ruins and hears Diana's voice calling, "Big sister...", and the scene turns to an uncovered frame of Genocyber, with a baby crying in the background. The ending is quite unreasonable and unexplained. What happens to Ryu and Mel? Are they the last humans on earth? The existence of other cities is not known, since most were destroyed previously by Genocyber.
Sounds kinda like EoE. Though tang is replaced by death.
