In keeping with the tradition established by this pool I'm uploading the two side-story book cover page posts uploaded in the past year. I'll also position them in the pool relative to their upload date on pixiv.

This big book clocks in at 96 pages, 92 of which are the actual content. The first 44 pages are also available to read for free at the source link. It also abandons the strict 4koma format and has a traditional comic layout with rows of variable-sized panels, but it's still a silent comic.

There's been an incident! An unknown threat has wreaked havoc throughout Gensokyo and caught the attention of all your favorite playable heroines! ...and of Kyouko and Kogasa, but only because they accidentally run into a monster that's far more formidable (and hungrier) than any they've met before...

Features: Every Temple resident except Lily. Reimu and Marisa. Remilia, Sakuya, and Koakuma. Kanako, Suwako, and Sanae. Youmu and Yuyuko. Rumia, Keine, Mystia, and Wriggle are also here. I think the monster is all-new, but is probably based on some Japanese myth I don't know about. Mokou, Iku, and Akyuu appear in speech bubbles. In the celebration at the end: Tenshi, Mokou, Alice, Kagerou, Reisen, Nitori, Cirno, and Suika.

My highlights; pervotron could add more (as per tradition):

Multiple instances of girls having to get food before going on their Adventure™!

Remilia feeding Koakuma is super cute. Suwako sleeping on Sanae's lap is also cute. Kyouko constantly worrying about following Byakuren's rules over her own safety is *kinda* adorable in a uniquely Echoes Kyouko way, though I'm probably misinterpreting some instances and she's really just suggesting they seek her help instead? EDIT: After Moonspeaker's translation of the title, yeah I think I totally misunderstood Kyouko here. This may be a silent comic but it sure is dialogue-heavy... EDIT 2: And when reading it again while uploading the sample WOW I got it not only wrong but *backwards*

Rumia and Wriggle using their powers to heroic ends. Lots of heroic entrances to go around in this story, actually. Sanae, on the other hand, seems to be in it exclusively for the glory.

Kyouko hurts her bum at one point, aww.

Hachimaki takes advantage of their new art style to draw some pretty eldritch body features on our monster.

Monster learns the hard way what happens when you try to eat a ghost; seems confused by the very idea of ghosts.

Kyouko, ever-flowing bastion of kindness and purity, does not want to destroy the monster outright, despite what everyone else thinks.
