Eromanga Sensei volumes 10-11 read:

I've been busily reading the new Eromanga Sensei content the moment I discovered it, so I'm already finished with two of the three books.  The books have also been quite short so they're easy to finish.

In book 10 Masamune has some delicious erotic time with Sagiri, and a pointless date with Muramasa where he has to once again fend off her advances.  As though Muramasa could compete with Sagiri.  It's laughable.  Even in the book centered on Muramasa the moments with Sagiri were far more enjoyable.

Then in book 11 Masamune gets some erotic time with Elf, followed by some humorous time with Megumi, and finally at the end lots of romantic and erotic time with Sagiri where they spent like fifty pages saying how much they like each other.  It put a loosey-goosey smile on my face as the heartwarming content just went on and on.  So sappy!

These books are somewhat strange in that there doesn't seem to have been any reason for them to exist.  Nothing changed, nothing developed.  It was just Masamune and Sagiri enjoying their relationship together like you'd imagine they would.  Oh, also book 11 had Sagiri chatting online with Kirino for a while so that was fun.  I actually got to read about 3 waifus at a time instead of the 2 I expected.

These were definitely enjoyable books, the illustrations were very cute, but isn't it odd that the author wrote volumes like this and then quit altogether?  If he had used his time wisely, he could've reached the 'happily ever after' anime debut of Sekaimo by now, but instead we're as far away from that moment as ever.  Instead all that's left is volume 12 and then nothing.  I'll have to read volume 12 to see if any major developments happen then, but it seems like a bad way to approach things based on what I've seen so far.  Why do authors write such long series if they have nothing important to say in them?  And why on Earth would you write a long series and then quit midway when you could've been finished by now if you had only tried?

This was very good content, but it isn't the content we the readers have been waiting for.  If we're only going to get one or the other, I wish he had written the ending and not this fluff.
