Ronpaia (Circle)

Fate slice of life doujin. Volume 18's been released in 2015.

Fanbook of Ayako Mitsuzuri. By and for weirdos that actually do care about her.

Rider gets smaller once again.

Mashie fanbook about rising in-game relationship parameters, because apparently they do something.

"This house, it's like a women's dormitory, isn't it?" Also, Tiger gets a makeover.

One of several "One day!" complementary books. … it's basically a harem, but not a harem, all right?

Another Mitsuzuri book. Because even platonic harem's never big enough.

Yet another fanbook. No waifu - no laifu.

Fanbook dedicated to Mitsuzuri Ayako. Probably the first one, if they were to be considered a series and had any semblance of solid continuity. At least it's not about Makidera, that would be really weird.

"I made this \[book] with vigour and willpower. \[…] nothing else."
