Come on Kita, don't defend Ryo, she deserves all the rage from your mom, not only from the blonde dorito sisters.
Since we can't heard the music, the highlights of the chapter are: Kita's mom not making a fuss about Bocchi being a girl, her only complaint was that she maybe was "playing around with her" and that was clarified it wasn't the case, so she accepts her as a partner for her daughter.
And Kita singling out Hitori-chan separately from her friends (she's more than that) while also saying she's gonna do this for her.
