Synopsis from MAL
A struggling manga artist and pizza boy extraordinaire in his late twenties. Seems like your average Joe, right? Wrong. The protagonist of Boku dake ga Inai Machi, Satoru Fujinuma, possesses a very special gift. His supernatural ability, which he calls "Revival," triggers a time leap, sending him back to right before certain life-threatening events occur, allowing him to prevent these tragedies and save the day.
After a devastating incident in his present day life caused a sudden "Revival," Satoru was sent back to when he was a young, elementary school student, one month before his classmate Kayo went missing. He is forced to solve the mystery behind the serial kidnappings in his hometown and protect his childhood friends.
Boku dake ga Inai Machi is a thrilling, Sci-Fi series that explores the past and present of the main characters in a unique way. Who is the mystery kidnapper? Will Satoru succeed in saving the day when his friends' lives count on it? And will changing the future have any negative effects on present day life?
Amazing story setup, keeping me hooked and i can't wait for the next episodes!
This anime might be one of the best this season!! Personally reminds me of Steins;Gate (time travels, trying to change the past/future)
