Don’t know if these scans were ever posted but I found them on someone’s weibo.

The scans basically talk about what Nishiki did on the day Kiryu’s storyline in Zero began. We also learn Nishiki 1) doesn’t like 2-in-1 shampoos 2) daily hair routine is shampoo–>conditioner–> hair treatment for 1 hour–>hairdry for 30 minutes.
