Makoto Naegi

Hi, I'm Makoto Naegi, the most ordinary student of the Peak of Hope Academy.

Makoto got his talent as the Ultimate Lucky Student by winning a lottery out of completely ordinary students, which led to him joining Hope's Peak Academy as the Ultimate Lucky Student. In addition to this, he was caught up in a bizarre series of events on the day of his selection which ended up catching a jewel thief and burning the selection ticket. Following the fifth trial, just before Makoto's execution can be completed, Alter Ego suddenly appears and is able to prevent Makoto from dying by opening up a door on the floor. He is then rescued by Kyoko, going on to defeat Junko herself and survive the whole ordeal.
Makoto's luck also comes into play during the events of the Final Killing Game, saving him from multiple dangerous situations. While his luck isn't nearly as powerful as his predecessor's or Izuru Kamukura's, his luck pattern is different from those two, and is difficult for Junko to analyze and predict. Thus, Junko predicted that he could possibly ruin her perfect layout plan, which ironically also made Junko allow him to live for the Killing School Life.
Makoto discovers his true talent as the Ultimate Hope during the sixth and final trial of the Killing School Life. Interestingly, unlike most other talents, Makoto being the Ultimate Hope isn't recognized by Hope's Peak Academy, but rather earned for defeating Junko, the True Ultimate Despair. Unlike Izuru Kamukura, who's Ultimate Hope comes from him being the embodiment of talent, Makoto's Ultimate Hope comes from his unusual amount of optimism and determination, which Makoto even comments on.
As the Ultimate Hope, Makoto proves to have an immunity to Junko's tactics, built to make people fall into despair. Combined with his luck being difficult for Junko to analyze, causes her to leave him alive because defying her would be full of despair in its own right.
