Now sealed inside a suit of armor old when the world was young, Emma Knight will have to master newfound powers she’d long regarded as merely myth; all whilst navigating the breakdown of society and delving through dungeons in search of the truth behind the apocalypse. How’s that for a Sworded Affair? What to expect: LitRPG, Progression, Dungeons and the Apocalypse. What not to expect: Harem, Smut, Drama or Tragedy.

From a caste based high school, bottom-tier Naomi Masatsugu is caught up in a summon of his class to a different world. However, as soon as they arrived the king said, “This guy is unnecessary because he only has clumsy skills ” and it is concluded that he is to be forced to administer the orphanage, which no one wants to do.
