30% ACCURACY.

while at first, he’s willing to write this off as simply a fluke, or random interjection from his thoughts at the time. he has a similar one the next day, and the day after that .... ultimately until this points to two weeks. it becomes clear that such a prediction is looking a surefire way to come true. so hiro makes a choice: to try and stop this for once and for all.

hiro chooses to make himself repeat his school years multiple times, in order to secure himself to be part of the same year as such a class ( even if this means joining hope’s peak’s aforementioned reserve course ), but luckily recieves a prediction that he, in fact, will be scouted for the ultimate clairvoyant of the same class and year. he keeps track of the forums predicting the other students said to be scouted for hope’s peak, and tries his best to learn their likes and dislikes. he meets up with sayaka’s manager again and tells him that giving her more leeway will certainly create better music and a lifestyle for her, he meets up with an underground gambler, asking him if he’ll reconsider trying to beat his next opponent. he attends an anime convention, asking fujiko yamada if she’s willing to truly put her work above her brother, and meet kanon nakajima to tell her that her cousin does appreciate her and that truthfully he wants her to be happiest with someone who will truly appreciate her in an attempt to fix everything he deems as a risk from such a bulletine board.

despite this, his predictions remain the same. even after he takes one step onward,  meeting up with the postman rumoured to deliver the ultimate lucky students mail to ask them to make an important deal out of it so the lucky student feels special. trying to question jin kirigiri about his relationship with his daughter and being firmly rejected. his predictions remain the same even after he joins hope’s peak after that, making his damned best to ensure that everyone gets on in good terms, resolving as much conflict as he can ( obviously some pieces are a lost cause, but- ) in fact, the moment the tragedy hits, it gets worse. 

one night him and leon stay up late because neither of them can sleep, and when leon asks him to give his prediction, hiro sees a vision of his execution. he follows kiyotaka to help out with his early morning chores and ends up opening a door for him only to have a vision that it’s his body there, laying dead on the floor rather than before him. he calls junko mukuro in midst of a vision of seeing her getting impaled by spears, his own hand smaking a bottle against sakuras head in the midst of a talk about strength with her. each of these leading up to a series of events in which he feels he cannot control. 

except, there is one thing he manages to change: in his prediction of her death, he opens mukuro up to the reality earlier that junko will ultimately betray her, no matter what. and in the night in which everyone essentially has their memory wiped, she tells hiro she won;t wipe his memory, as long as he plays pretend that he’s dead so that they can get the upper hand on junko when the time comes, and hides him up in the morgue under the pretence he has passed away, giving him the headmasters key in order to get back down and overcome for now. 

the killing game begins as planned without hiro, but it’s with his and mukuro’s plan that they manage to stop the first motive being aired on that day. instead, mukuro taking centre stage for her and junkos plan much earlier than expected, while junkos distracted - it’s hiro who breaks in the headmasters office and essentially shoves junko out in order to stop the killing game, obviously believing himself the victor, he doesn’t see the door that closes in behind him, or the screen that greets him straight away.
