Retranslated quite a few lines in Astral Bout 40 and MOST of Astral Bout 41 (Feel bad for whoever paid & commissioned that original 'translation' man). If you're not concerned about that then jump straight to Page 91 for the Bonus chapter.
Brightness graded to free samples from the artist's Pixiv. They weirdly have different shading between AB40-41 & AB42-43 which makes the former looks a tad overblown/brighter than my preference.

Kept searching for how it started, but it seems like this is the beginning. Its implied she is mind and body controlled and memory manipulated by the game system by some unknown person.
