It may collide with the @relative forgetji next door, but the plot is different. It is the same dormitory with undead creatures, zerg, Er Enoch (Ophi Enoch), and vampire ghosts, but the transformed knights are different. The human form transforms into: Jin Dou, Snake Fang, Delta, Sword Scorpion, but the weird form will transform into: Great Sword, Dark Moon Cavalry, Dark Armor, and Emperor of Earth.
Nangong Shuo, who was originally a fat and boring man, unexpectedly traveled to the world of swords and became the King of Spades, an undead creature from the South Sea Caucasus. After experiencing the extreme war, he accidentally came to a new world in which everyone can awaken to become... As a knight, Nangong Shuo, who had just arrived here, awakened the Golden Knight and the transformers of some villain knights, and was assigned to dormitory No. 777. The roommates here were all weirdos, not a single human being. So after they found out their identities, they started a 'fun' game.
It seems like there is no other book
