Susukihotaru is paired with Riken in the Ministry of Spirit Affairs. Like Zakuro, Susukihotaru is a 'Hanyuu', half-human and half-demon. Unlike Zakuro, she is shy and timid. Ever since she was young, like the other girls, she grew up in a society where hanyuu's are seen as bad omen. Thus she has always been scared of humans, so scared that she doesn't even look into their eyes, until Riken came to her life.

She has a strong interest in horoscopes and believes they have real impact in life. She has the power to empathize with objects and people, as she can see what's happened to them/it when she comes in contact with it.

Her voice is medium high. She's kind of timid and quiet. 

Line One she is around the other girls, and she's comfortable. She's mentioning this to Zakuro to try to disway her anger and take her attention.

Line Two she is shyly talking to Riken. She isn't looking at him and is very timid.

Line Three she is shocked because she called Riken scary and he heard her. So she's a little scared.
