In a bowl, add orange juice, red miso paste, orange zest, and mirin. Whisk the ingredients until nicely blended and set aside for now.
Season scallops with white pepper and set aside.
In a large skillet over medium-high heat, add oil and when it starts shimmering, place the scallops, seasoned side down. Cook them for about 1 ½ to 2 minutes per side or until golden.
Transfer cooked scallops to warm plates, reduce the heat to medium-low and also move the skillet off the burner for a couple minutes.
Bring skillet back on the burner and add butter.
When melted, add the minced ginger and sauté it for only 1 minute.
Add blood orange sauce, stir well and bring it to a simmer. Cook the mixture for 5 minutes or until it starts to thicken a little.
Add nira chives, stir until incorporated and cook for 2 more minutes.
Spoon sauce over scallops, sprinkle more chives on top and serve immediately with rice and steamed veggies.
