Haruka Shirosaki is Hana's mom in Watashi ni Tenshi ga Maiorita! She's a striking woman with long black hair pulled back in a low ponytail (tied with a light blue ribbon) and purple eyes.
As a supporting character, she doesn't get a ton of screen time, but she plays the grounding parental role in the series. Fans often appreciate how she's written as a genuinely caring mother without being overbearing—she lets Hana do her thing while clearly looking out for her.
