Daigo Nishijima/Relationships

Maki Himekawa
Daigo and Maki were Digidestined in the era before Tai's group ever set foot in the Digital World. Following their own adventures to defeat the forces of darkness, they found themselves up against the Dark Masters. Following Homeostasis' transformation of four-fifths of their Digimon into the Harmonious Ones, Maki's heart was broken when her own partner was sacrificed to seal them away. Daigo and Maki appeared to remain in contact, studying together at a university. The two began dating at this time, as Daigo wanted Maki to stop obsessing over the past and how to reunite with Tapirmon, as it was wearing her out. His reasons for this relationship were both romantic attraction as well as trying to save Maki from her obsession.

The two remained in a relationship for sometime before eventually breaking it off. The two had a somewhat strained professional relationship, as Daigo's attempts to tell their successors as the Digidestined the truth clashed with Maki's ulterior motives to reboot the Digital World in order to reunite with her lost partner Digimon. Later on, Daigo sensed Maki's death in the Dark Ocean, lamenting on how he failed to save her.
