Hagi no Ane

As Hagi's older sister, she carries a bold personality and a deeply rooted fujoshi spirit. Upon noticing that her younger brother had developed feelings for Kohaku, who was dressed in masculine attire, she misread the gender dynamic between the two—yet still responded with remarkable open-mindedness and eagerly supported their relationship. Her strong appreciation for cool-looking women, combined with an overactive imagination, frequently leads to comedic situations. Within the story, she serves as a key supporting figure who helps propel the romantic development between her brother and Kohaku.
