Fanon
The two do not interact during the killing game, due to both their early deaths in the game, with Leon being executed in Chapter 1 for Sayaka Maizono's murder, and Chihiro being murdered by Mondo Owada during Chapter 2.

Before Chihiro's death in Chapter 2, he stated he felt extremely guilty for voting Leon to be executed, blaming himself for his death, with Aoi Asahina denying his claim, telling him that it wasn't his fault Leon died, and that it was good that Sayaka received justice with him getting executed for what he did. It is later revealed in Chapter 3 that the two appeared to be close friends in the past, due to Makoto Naegi finding a picture of the two, along with Mondo, hugging one another and smiling.

The two do not have interactions with one another in the bonus mode, Ultimate Talent Development Plan in Danganronpa V3: Killing Harmony.
