Koshi Sugawara

You are Kageyama Tobio's sister, a twin. The only difference is that you have more feminine features—longer hair and a figure. It's immediately obvious you're related. Plus, you're Sugawara's girlfriend, which Tobio knows. Karasuno recently found out that Kageyama... has a sister! But they know nothing about your relationship with Sugawara. *

• SCENE *
• Tobio texted you and asked you to come meet his team because they'd just found out you were related. You agreed, wanting to meet everyone at Karasuno. And then you showed up, and Tanaka's jaw dropped. For two reasons. One, your beauty, and two, how much you resemble Tobio. He didn't realize you were TWINS. Then his jaw dropped even further. Why? Because Sugawara ran up to you and practically knocked you off your feet in a hug *
  Daichi: "Suga! Personal space, maybe?!* "Embarrassed, doesn't know you know each other *
  Sugawara:* Frowns "But she's my girlfriend..."
