Maki Himekawa is one of new characters of Digimon Adventure tri.. She is working with King Drasil and Mysterious Man.
Maki is a young woman with fair skin, chin-length brown hair, and amber eyes. She wears a grey shirt, a black blazer with a pocket on each side and two black buttons, a black business skirt, brown pantyhose, and black high heels.
Maki was one of the original DigiDestined and was partnered with Tapirmon. During a climatic, losing battle against the Dark Masters, Maki went to comfort Megadramon (Tapirmon's Ultimate form), then tried to rally Daigo Nishijima, who was ready to give up. However, just as all seemed lost, she was possessed by Homeostasis, who used her Digivice to make the children's Partners digivolve. After regaining control of her body, she begged that Megadramon was the only one left, while Daigo told her there was no time. She then watched as the other four Digimon became the Harmonious Ones while Megadramon sacrificed itself to channel an immense energy attack against the Dark Masters. Heartbroken, Maki questioned why only four of the Digimon were saved, and stared in shock at her broken Digivice. Afterward, she became obsessed with finding a way to see Tapirmon again.
Years later, Maki and Daigo attend the same college. Maki learns the Digital World can be rebooted and informs Daigo, telling him that she intends to continue pursuing this plan after she graduates. Worried, Daigo tried to dissuade her from it and asked to instead be her "new partner". Although Maki laughed at his awkward manner, joking that he has been watching too much TV, she agrees to date him.
However, at some point Maki and Daigo broke up. Both also became coworkers at the Incorporated Administrative Agency. At some point, she was emailed by the Mysterious Man, who claimed the reboot would be possible if they used Meicoomon and asked her to collaborate with King Drasil, to which she agreed.
In the week before June 19, 2005, she discusses the witnesses of the infected Digimon with Daigo over the phone, while using her computer to monitor the locations of the DigiDestined of 1999 and note that the 2002 group is missing.
After the Digital World Reboot, Maki goes missing in the real world as Daigo looks for her. Maki is in the Digital World looking for her partner Tapirmon so they may be reunited. Maki is successful as she finds Tapirmon but he does not remember her and becomes frightened by Maki's insistence that he remember her.
