This was a really good chapter. Super interesting language discussion, really cool lizardmen who do not show up nearly enough as full characters in manga, really good comedy too.
That ending was perfect; They cant tell a male human from a female any easier than we can distinguish between alligators. If anything, his voice might be high pitched and feminine to them.
Aw this manga is super sweet, I love it. It's also nice seeing how the mangaka can incorporate real animal physiology with that of fantasy beast people. Reminds me of a linguistic Dungeon Meshi.
