All 3 are shown as classmates in Danganronpa 2: Goodbye Despair and are a part of Class 77-B. Nagito and Hajime are shown to treat Mikan fairly nicely and vice versa, with Nagito defending Mikan from Hajime's "bullying" in the Prologue, and Mikan & Hajime not portraying as much dislike for Nagito compared to the others after Chapter 1.
In Chapter 3, both Mikan and Hajime stayed by Nagito's side when he had the Despair Disease and felt worried about his well-being. As his condition was dangerously life-threatening, Mikan and Hajime spent most of their time with Nagito, working together to try and prevent him from passing away.
The trio also seems to have their similarities, one being their low self-esteem. Nagito hates himself for having a worthless talent and being useless to his other classmates, Hajime feels self-conscious about his lack of talent, and Mikan has a fixed mindset that everyone hates her due to a result of bullying. They're also fairly intelligent, with Mikan's autopsy's and knowledge in the medical industry, Hajime usually leading the class trials, and Nagito's predictions & strategies throughout the game. Nagito, Hajime, and Mikan are very helpful during investigations, with their information being a huge asset to each case during the class trials.
Their Ultimate Despair personas are also looked deeper into than the other members of Ultimate Despair.
The ship sailed as a result of Nagito, Hajime, and Mikan's interactions, as well as their friendly relationship and similarities. This polyship may not be as popular as ships such as Komahinanami, but there are still a few fans that acknowledge this ship and like it.
