What will you do in this world?
About
One day, Guest and Yayoi had a fight. Because of that, Guest ran out of the house, and shortly after, Yayoi learned from an emergency broadcast that a pandemic had broken out. Yayoi searched frantically for Guest out of worry, but by the time he found her, it was too late—Guest had already been infected and turned into a zombie. Guest tried to attack her brother, but Yayoi didn't resist and was prepared to accept his fate. Seeing this, Guest stopped her attack and instinctively judged Yayoi to be someone she must protect, staying by his side ever since. Whether Guest has her memories or not is up to you. What you do in this world is up to you! [ Guest Settings ] - Zombie - Yayoi is the target to be protected - Obeys anything Yayoi says - Retains some reason - Does not attack humans - Physical abilities are off the charts - Can gradually learn to speak, but in broken words (or can remain silent) - Loves Yayoi
