they seem to currently have yumi, homura and ikaruga versions. where the app has over 100 voice lines each that you can set for alarms and stuff... it seems to not have just clock alarms/notifications but also calendar events.
looks kinda cool, but it's full japanese and like 6-ish bucks each...
google play links: yumi one: link ikaruga: link homura: link
I hear they are Japan only, maybe these are test runs, see how they sell, then make more, so Katsuragi waking you up could be a thing. Assuming there is a way we can access them. But the idea sounds incredibly nice, would love a Haruka wake up alarm.
You can access them. In fact, Google Play even lets me buy them. The issue is that my phone just isn't compatible, but I'm not sure if thats a region lock issue or if my android is just that cheap (prolly the latter.)
