I am BD , Level 15. I want to buy these items below. but I m not sure that I can use it . Why two slots at right bottom corner are in red line color?Does it mean I cant use?

I m doing Sanctuaries of Constellations Quests. When I obtain the Sanctuary of Cup , It said I need "Blade of Star Warrior". How do I get it ? Do I have to buy it ? if so where I can buy it . if not Where Do I look for it?
