"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."
And in this nation, swearing to the dragon 
is the highest form of promise.
وفي هذا البلد، القسَمُ بالتنّين هو أبهى أشكال الوعد
Und in diesem Land ist
bei den Drachen zu schwören
Y en este país, jurar por el dragón
es la mayor promesa.
Y en este país, jurar por el dragón
es la mayor promesa.
Et puis, dans ce pays,
jurer sur le dragon
E in questo reame, giurare sul drago 
è la forma più alta di promessa.
E nesta nação, jurar pelo dragão é a forma
 mais alta de se prometer alguma coisa.
А ещё клятва драконом в этой стране
означает нерушимое обещание.
