Can they just reboot Nanoha at this point? Vivid onwards is a mess and they spent years teasing us into VivioEin only to NTR Vivio, if you're going for a pairing fucking stick to it, I'd be fine with a reboot that moved us back to just before StrikerS
You are so right, give us some high school adventures and then by the time they become adults again reintroduce Vivio in a better story and setting.
"Jeez Corona", don't you know it Rio. Cute little story, we need more Corona, and Rio.
