Kirizono

Kirizono is a femslash ship between Kyoko Kirigiri and Sayaka Maizono in the Danganronpa series.

Canon
Kyoko and Sayaka haven't been interacted much. The one thing that connects them is the fact that they both have been Makoto's love interests. It was confirmed when they occurred in his hallucination. Sayaka's ghost has been representing his first love, implying that Kyoko is his current love.

Despite being love rivals (although it's not clear whether Kyoko had feelings for Makoto back in Chapter 1), Kyoko told Makoto about a possibility that Sayaka left an evidence pointing to Leon being her killer because she still cared about what happens to Makoto.

They also have an event together in Danganronpa V3's bonus mode, Ultimate Talent Development Plan. In it, the two are about to play a volleyball game. Sayaka asks if Kyoko is alright as she may be tired, being always busy with detective work. Kyoko asks the same, reminding her she's always busy with being a pop star. The two decide not to worry and focus on the game by doing their best.
