As mentioned in the synopsis, the Love Live Sunshine SID novels are booklets around 20 pages each sold with the blu-rays of the series. The first three volume are individual stories about the 2nd years, the 1st years and the 3rd years respectively while the last volume is about aqours preparing for a mini-concert during their summer vacation.

On one hand it’s hard to be harsh on them because they don’t have any ambition other than being a bonus for the fans but you can tell there’s barely any effort put into it, they’re most often just summaries of events happening in anime, retelling of elements that you already knew about the characters or hamfisting once again some of the romance. Occasionally, some of the stories aren’t that bad, even if they’re banalities, they’re what you can expect from this type of work but the interesting bits are very few.
Even when ignoring the trite subjects, the writing itself is also particularly irritating, not in that it’s too simple, I don’t expect the prose to be elaborate in something like that, but these books are filled with giggling and shouting and heart and stars emojis everywhere. Everything is done to make them have a cute speech and antics but it doesn’t work at all in written form and it becomes very apparent that it’s only there to appeal to the creepy otaku part of the fanbase.

At least I can say the chibi art is pretty darn adorable.
