One of the reason I love Isekai wa Smartphone, just seeing some light-hearted moments and enjoying their leisure from time to time. I should really start reading where I left off in the Novel huh.
Does author have a problem with onee-sans being part of the harem? He already got plenty of lolis and now they're adding even more. Sure, that appearance was the first lord's wife and having her as a heroine is kinda creepy but not having an onee-san is just sad.
So the "ghost" got duplicated as well? Or is the same being inhabiting a number of frames? I hope it's the latter, otherwise one frame might decide to "play a prank" one day and rebel.
