Really good chapter. They're about to create another mess.
We got more information on the pink bearer! As expected, she's elite, and she's bought Kunishige's sword before!!
Regarding the EBs: are their powers connected to the first user's sorcery? Kuregumo's power is related to Ibuki's power. We don't actually know if Samura's sorcery had any similarity to Tobimune's, or if Uruha's sorcery was the source (sourcery hehehe) for Kumeyuri's.
For some time we've known about Kuregumo's power being similar to Ibuki's, but now that we're drawing closer to actually seeing their first use, that becomes even more interesting.
In particular, when we think about the Shinuchi! Did they capture someone to use it before Akemura? So that they could imbue the sword with the Mikaboshi power.
