Wow Izumo sensei really had the Bureau of Darkness set up in chapter 1, that’s really impressive! I can’t wait to learn what secrets these back up documents are holding, hopefully they weren’t too rain damaged. Seeing Shamiko revive the Bureau of Darkness is going to be one hell of a ride, and I think that this is when Suika is going to slink back into the picture. Remaking the Bureau of Darkness also means recreating a registry of the remaining dark clan members who haven’t been killed by Suika, and therefore represents the most dangerous endeavor yet. If Suika catches wind of this being developed and somehow gets in, she very well might try to finish the job she started...
On a lighter note, Shamiko’s mom having a “moment of weakness and difficulty as a parent” when Shamiko had never heard of the family registry was hilarious. I really like the fact that Izumo sensei has gone this far on the legal workings of the town and how this seemingly out of nowhere organization is actually the reason that they recieve any form of welfare or educational support. Kinda reminds me of the patchwork of cities across Japan that have limited local registries for queer couples to get access to some legal benefits.
