Touko helps aid Komaru through The Tragedy. At first, Touko only helped Komaru because of blackmail from Nagito Komaeda and was annoyed by Komaru's cowardly or stupid behavior. However, their friendship grew to the point of sharing beds together and helping each other climb up taller items. Touko constantly encourages Komaru when she is at the point of giving up.

During an interview with the crew behind Another Episode, Kodaka states that the game is about "the deepening friendship between Touko and Komaru." They continue to have very close friendship in Danganronpa 3 and Touko considers Komaru one of the closest and dearest persons to her, the other one being Byakuya.

It's also worth noting that in the original japanese Fukawa tells Komaru that she loves her, but this was edited out in the english translation.
