"Subaru's first day at the Roswaal mansion begins for the third time. The first time, he grew weak and died of unknown reasons in his sleep, and the second time, he was killed by an attacker. The sound of chains that he heard as he died the second time replays in his mind, waking him in a terrified, cold sweat. He has no idea what the killer is after, let alone who it is, so he makes a plan to leave the mansion on the fourth night and watch for the attack to happen.

Standing before Subaru is someone he never expected. The truth of the attacker's identity leaves him bewildered, and he feels everything crumbling around him as he dies yet again. Then, for the fourth time, he awakes on his first day at the Roswaal mansion. This time, the night of the fourth day passes without incident, and Subaru is stunned as he greets the morning of the fifth day... but then the situation takes an unexpected turn."
In this mansion, only Bubby and I can.
في هذا القصر، أنا وني-تشا الوحيدان
القادران على فعلها
Auf der Residenz können es wohl Bruderherz
und ich. Nicht mal Roswaal kann es.
En la mansión solo podemos Packy y yo.
Ni siquiera Roswaal puede.
En la mansión solo podemos Packy y yo.
Ni siquiera Roswaal puede.
Personne ici n’en est capable,
Roswaal compris, sauf moi et Ti’chat.
In questa tenuta possiamo farlo 
solo io e il mio tesorino.
Nesta mansão, só o 
Nii-cha somos capazes.
В этом особняке — только мы
 с братиком. Даже Розуэлл не умеет.
