Touko Fukawa and Kyouko Kirigiri hardly have an opinion of one another. They do not interact much, save for a few lines exchanged during the class trials. Despite this Touko and Kyouko are friends, as both girls made it out of the Despair High School alive and over the course of that time learned a great deal about one another. Their lives are precious to each other only in the way that, the other would be deeply saddened and put into grieving were that life to be lost.
Considering that both candidates have a tragic past and troubles with their families, as well as insecurities about their bodies, if it does not found the very basis for a friendship (which is canon, they are friends), it could potentially be a relationship, if only the two interacted in a much more frequent way.
Though Touko Fukawa and Kyouko Kirigiri do not have much interaction with one another, a ship has been born between the two of them in a universe where Byakuya Togami and Makoto Naegi would perhaps be a thing.
Though not much art or fanfiction exists for this coupling, it would be a possible pair, even if it's a "crack" pairing, considering that they both were a part of Class 78 and their killing game; the two were, as well, survivors of said killing game. The two, background and history wise have things in common and that foundation would make for a greater understanding of the other person in the relationship.
