Spicy Ageha Designer
She's the head designer behind Spicy Ageha and basically the face who got the brand off the ground as a charismatic model. She's the one who originally connected with Ran Shibuki and has been supplying her with Spicy Ageha cards ever since.
Fans note that she's pretty protective of Ran—she's actually told her not to chase after things too hard. When Ran bombed the audition to become Spicy Ageha's representative, the designer showed up in Episode 23 with premium rare cards to cheer her up, which says something about how much she cares.
She doesn't show up at Starlight Academy much, which makes sense given how busy she probably is running the brand.
