Yo. This chapter isn't actually posted in where I am getting the raws, so unfortunately I can't do much about it.
While I did think of attempting to write what might have happened based on the title of the chapter and what happened afterwords, I don't have much confidence in writing anything Honkai Impact 3rd related and couldn't be bothered to do research for just one chapter.
The title is [Elysia's Little Secret? First Meeting with Mobius.]
You guys can probably assume what this chapter is about.
I originally wanted to stop at the previous chapter before I went to bed, but like... didn't wanna bait yall.
I can just guess that it starts with the author first compling Seele's time with Elysia until they arrive at Fire Moth Headquarters, where Elysia takes her time to introduce various areas and surprises Mobius with Seele by privately showing her because it was already previously mentioned that Elysia didn't tell Mobius about this prior to her trying to convince the Fire Moth executives.
So that's probably what would have happened this chapter.
Be satisfied with just that.
Peace.
