Small "tsu" at the end of "Biku" on page 9 means the abrupt ending of the vowel and is the most likened to either hyphen at the end of an incomplete word, or, more accurately, to an exclamation sign in case of onomatopoeias.
@Glomoro most literal would be "A case of ending up living in the countryside with a female knight who came to my house". SO you're right, there's no "we" in the title whatsoever.
@TheDerangedOne And I'm saying that's a matter of having enough skill together with strong enough vocal cords (Meowth) or telepathy attuned to humans (Mewtwo). It's not an inherent feature of species.
