Rooftop Sword Master

After being beaten up and put into a coma by eight of his classmates at Nun’Gwang Middle school, Se’young woke up after nine long months and found out that his father committed suicide by self-immolation in an attempt to get justice for what happened to him.
As a result, the investigation re-opened and the attackers who tried to sweep it under the rug received a proper sentence for their crimes. But Se’young was unable to assuage the anger and fear he felt for the unjust world.
Se’young thoroughly hid from this sort of world.
The sun would rise and set, the seasons changed, and not once did he step outside of his home. But one day, a sudden and strange sound enticed him to open the door…
Embedded in the center of the rooftop was a gigantic blade emblazoned with the words “War Sword” and with it, came the whispers of a God.
