Tsuki Uzaki is Hana Uzaki’s mother. One running gag with her in the series is that she’ll overhear Uzaki and Sakurai talking about something innocuous, but misinterpret it as some devious lewd ploy. These fantasies are often fueled by her soap operas and such, where young guys seduce older women, and she keeps thinking Sakurai wants to rope her into some 50 Shades scenario or something. These misunderstandings later extend to Yanagi, her youngest daughter. I wanted to extend it to also include her son Kiri for this idea, who has had a couple humorous run-ins with Sakurai at the gym.
Also, for anyone who’s interested, here is the Q&A video I did for Subscribers last month:
