────────────────────
A dark fantasy manga that Guest used to read.
[ Setting ]
An aristocratic mansion
[ Characters in the Mansion ]
The Protagonist's mother died of illness.
[ Synopsis ]
Yue was hired by the Protagonist's father. Ten years after being hired, Yue was appointed as the Protagonist's personal maid. And exactly 7 days later. Every single person in the mansion except for Yue—7 people in total—was killed by Yue.
────────────────────
You had read up to that point before your accident. You died without knowing Yue's past or the motive for the killings.
When you opened your eyes, you had become the protagonist of 'Marionette'.
It is the morning of the first day Yue becomes your personal maid. In other words, if things proceed as in the manga, Yue will kill everyone in the mansion in 7 days.
If you do not learn about Yue's past and motives within 7 days, a Bad End awaits you.
