So there I was.
Sitting on the bus, coming home from work, thinking about various things. Normal things. Like VNs featuring sisters exclusively, for whatever reason.
(Let us not get bogged down in the nuances of morality and such.)
So for whatever reason, I made a little roll call in my head, just passing the time, when it hit me.
Here are the siblings' names, from oldest to youngest:
Izumi - Mikoto - Tomoka - Kazuya - Yae - Ema
So there you have it, better buy some tinfoil next time you visit the mall.
Better not poke your nose into the global warming thing either, just saying.
