Merry: (acting cagey and secretive, seemingly avoiding Renko, spending a whole bunch of money on one transaction)
Renko, internal monologue: I knew it! She's secretly turning into a youkai! And she's leaving me out of it! :(
Renko: All right, Merry, spill the beans! What have you been up to!?
Merry: ... I've been getting started on becoming a naturalized citizen of Japan, like my ancestor Lafcadio Hearn before me!
Renko, completely thrown off: Oh ... uh ... have you decided on a Japanese name? He changed his name to Yakumo Koizumi, y'know ...
Merry: Well, yes! My given name will be "Yukari" (written as "紫"), and for my family name, I'm considering ...
Merry: (gets down on one knee, reveals that her big purchase was on a ring) ... Usami
Renko: (surprised Pikachu face)
(6900 years later, but also 700 years earlier:)
Yukari, in the middle of planning out her Youkai Expansion Project: Wait I just had a much funnier idea.
