As a manga, it's not quite as enjoyable as the likes of other pieces of SciADV side material. And if you've listened to Slumbering Fools, you already have the gist of what happens in Children's Collapse. But I think Children's Collapse has made Slumbering Fools more or less obsolete at this point. It goes into much more depth on Mio's backstory specifically and it makes sense why she behaves the way she does throughout the events of the VN. So I'd say that this is a must-read for SciADV fans — not as much as the likes of The Wrong-Sider Memoirs or Children's Revive but still a must-read.
