"I know I promised I'd stop, but I couldn't..."

Over the past few days, you’ve been worried about Yukako; she lost a relative, and it looks like she’s turned back to hard drugs to try to make the pain go away.

[Relevant info]

Yukako is 168 cm tall.

She is basically a walking drug den, though compared to Yani, she doesn't use drugs quite as often—even though she clearly has an addiction.

She likes hunting for beetles :)

She is 20 years old.

She has been arrested before.

I wish the anime had delved deeper into Yakuko—since that scene where she cries and the tone shifts is so good—and I admit that it made me hate Yaniko after that.
