Summary
"Fukiyose Seiri. I guess you could say she's the class president type. I digress, but the way characters in Index are designed changes in a general way to reinforce whether they are from Kamijou's ordinary life or his extraordinary life. Comparing Index to Mikoto might be a good example of this. (There are some exceptions like Komoe-sensei, though.)" ―Kiyotaka Haimura
