Yeah, it kind of feels like the author kind of gave up on Hifumi's character arcs lately. She felt like a more important character in the early chapters, part of the main cast. Now it feels like she's been demoted to a complete side character. :\
I still feel this even in this chapter that's about her. It feels like she doesn't have any presence anymore.
I thought she had a pretty fine presence, she's still her awkward self but it was nice to see Hifumi deciding to take on Hajime for the sake of keeping their job smooth. I think she is gaining confidence, I'll agree it's been a slow progress since there had been a distinct lack of Hifumin but I like the chapter and would welcome more like these.
The plus point in this was the minimal newbies' (Momiji and Narumi) scenes.
