First of all, I'm not sure if it was intentional, but to me hibiki looks like cagalli yula athha from mobile suit gundam seed and seed destiny. and that has made her one of my favorite characters. also just a idea but how about making a event for hibiki where she cosplays as cagalli for the mc and they do some roleplay, you could probably do something similar for mako, by making her cosplay as lacus clyne a idol from mobile suit gundam seed and seed destiny. just as a couple of examples. and i know that there others who could have a cosplay event or events.
For the time being, my own android builds do not install on my phones or emulator. But I managed to get the game running on android using this method:
