Poor Jun whenever she's in class and MC has an interaction with someone. Probably hopes Touka doesn't notice or calls on her. Though with her growth spurt I imagine all eyes are gonna be on her more often lol
All that info on Hibiki's necklace makes me think (even more!) that the same thing, or at the very least, something similar was done to that crucifix MC was given. Especially with the lore dump that happens afterward.
Also probably already know or have fixed it:
Latest scene with Inawyn doesn't appear to be available in the replay gallery
