I randomly read the first volume of 空ろの箱と零のマリア and also randomly felt like posting about stuff I’ve read just because I haven’t done that for a while, so…
…overall, it was a decent book While some parts were a bit boring, overall it was enjoyable to keep me reading, especially after I had gotten past the first… 30? or so percent of it and more interesting things started happening.
Mentioning one random thing about the book, I’m not really sure why the author felt the need to write some parts entirely in bold text though, that was definitely a bit distracting at first before I got used to it. I’m guessing it was to not confuse the reader, but I have read plenty of books that did similar things without using bold text, and it doesn’t really feel like the presence or absence of bold text affects how easy stuff is to follow. If anything the bold text just threw me off and made it a tiny bit slower to read.
Random spoiler comments: It also felt a bit like the author just was being a bit too blatant about hiding information from the reader sometimes, with all the “x” did “xx” stuff, where the narrator even clearly already knows the information. However, while some of the"twists" just felt like something the author tried to force, it also feels like some of them made sense and were cool surprises, so I went with my usual strategy of not thinking too hard about it and enjoying the book
It was also a much faster read than a volume of SAO or Re:zero, so that was cool
