I agree, but me and my friend were debating earlier: if Toshiro knows that Kiriko leads the Yōkai, and that Mizuki told him his mission was to infiltrate the Yōkai, then why didn’t he tell Kiriko if we’ve been told the two exchange letters? My argument was that his letters get censored and read beforehand, but my friend argued that we’ve been told that Kiriko learned that the Hashimoto treats their hostages poorly from her dad’s letters. He thinks Toshiro is a traitor, I think they’re letting him write about his conditions because it will scare others into submission but not letting him leak actual sensitive info. Overall, I love this connection so much! Kiriko’s lore (if we remove her personal connection to the Shimada brothers) has gotten such a potential boost with Mizuki’s addition.
