So real question: why is there an incest tag? The only thing I've seen that connects to incest is Akira and Sera having some major siscon going on, but is that enough for the tag? I always assumed that the tag meant something explicitly incestual happened, like romantic or sexual acts. Or is there something of that nature in the future or that I missed in the available chapters?
It just doesn't feel like the tag belongs on this series.... yet. Really enjoying the series so far though!
