When Seo Jun-Ho and his companions sacrificed themselves to defeat the frost queen, they thought they were restoring peace to Earth. But after 25 years of being frozen solid, Jun-Hho thaws out only to find that nine more floors appeared in his absence, only one of which has been cleared! As the only one who holds the key to clearing the next floor and defrosting his friends, Jun-Ho must step up once again. But has this hero been in hibernation too long to take on the world’s fearsome new foes?
