A global pandemic and war led to the world's end, resulting in the emergence of weak metahumans. The protagonist, however, is inexplicably isolated in his apartment, protected by a 'Ultimate Shut-In' ability that prevents anyone from entering. This ability, though protective, also traps him, but it unexpectedly begins generating money and restoring power to his home. Faced with survival and a desire to reunite with his family, he is now exploring how to leverage his new situation.
