Ughh, you're questioning why it felt like it got twisted from the start yet its because of yourself for answering those questions and get into S class
The headmaster met him before the start of the plot and saw him use Blink and gave him an invitation. There is a small flashback in one chapter.
How the hell does he get into the academy?? Like... look at the situation he had, isn't he a fugitive(?) Orphan??? Like did he get an invitation to enter the academy or smth??
