Four is the no-nonsense SHSL Biochemist with a heart of ice, and the face to match. She doesn't put up with anybody's crap, and if she thinks you're too annoying for her, she won't hold herself back from dealing out harsh criticism. While she tends to be icy, she truly does want the best for her classmates, and is willing to face the truth, no matter how hard it may be. Her voice should be deep, similar to more serious characters like Peko Pekoyama or Kyoko Kirigiri.
