Dimension Totsu Lovers!!

After the antireality disaster “Monsters,” scattered across the entire Earth by the “Black Train,” drove humanity to the brink of extinction, 200 years passed.
Japan had achieved recovery through an antireality organization called the “Academy.”
However, behind a peaceful world, darkness always lurks.
There existed an unlawful group that disregarded human morality for the sake of truth, those called “Magicians.”
The protagonist, Houzuki Enju, is a “Magician,” and an enemy of humanity.
“Listen, my son. Infiltrate the ‘Academy’ and assassinate the student council president, Yoruno Sakura.”
Ordered by his father, Enju is stunned.
Up until now, he had spent his days solely researching magic, with zero friends. He suffers from communication difficulties and knows nothing of society.
There was no way he could infiltrate the “Academy” as an ordinary student.
Yet more than that, he was shocked by the name “Yoruno Sakura.”
Because it was the name of the girl who had been his first love…
the girl he had fallen for at first sight not long ago.
