What's New
Supporter plan is now available (hides ads)
All features remain free for everyone, just as before. In addition, a monthly Supporter plan is now available. While the subscription is active, advertisements on terra-log.org are not displayed; if it is cancelled, they are displayed again. You can choose 300, 500, or 1,000 yen, but what is provided is identical for every amount, and you can cancel at any time. Registering and filing consumption tax abroad is a heavy burden for an individual, so the plan is currently limited to residents of Japan. If you live outside Japan, or if you do not need the ads hidden, the pixivFANBOX donation is still available as before.
Added Endfield operator files
You can now track your read status for Arknights: Endfield operator files. Each operator has Operator Intel plus Basic Info, Personnel Review, and Files I-IV, and you can leave notes on each entry. Open it from “Endfield” in the sidebar. Your Arknights progress is unaffected.
Added chapter reviews
You can now rate each chapter from 0.5 to 5 stars and share your thoughts. Reviews are public along with your display name. You can post once every story in the chapter is marked as read, and review text stays hidden on chapters you have not finished. You can turn off other users’ reviews on My Page.
Your sort order is now remembered
The sort order you select is now saved in your browser. Opening the site in another tab or coming back later keeps the order you chose last time. The home page and the operator list each remember their own setting.
Sort options for story and operator lists
Added a sort control to the home page. You can choose from four options: release order (newest or oldest) and reading time (longest or shortest). The operator list can be sorted by release order (newest or oldest).
English durations now based on actual measurements
Estimated durations for the English version are now calculated from measured playthrough times instead of a fixed reading speed. Durations are substantially longer than before, reflecting how much more text the English version contains. Japanese and Korean durations are unchanged.
Fixed an issue where the story count and reading time inside chapter cards wrapped in the middle of a word and broke the layout on narrower screens in English. The number of columns now also adjusts to the screen width.
About Advertising
We have started showing ads so that the site can keep running long term. We aim to keep them within limits that do not interfere with reading or using the site. Thank you for your understanding.

Added a "Bulk Edit" button to the operator list page. Turn it on to show a checkbox on each operator's card, letting you mark all of that operator's Records, Files, and Modules as read or unread at once.
Track Operator Files & Modules
