How Can a Homebody Defeat The Demon King

Being a transmigrator is too good, though?
I opened my eyes in bed, and realized I had become a transmigrator.
My only goal in life had been to live quietly as a homebody, enjoying an ordinary life.
But I had fallen into a world filled with magic, demons, and destruction!
Fortunately, I ended up as a minor side character barely mentioned in the original story.
‘Then I’ll just lie down again.’
Selene returned to the cozy, peaceful bed.
Even by simply staying still, food, cleaning, and laundry service were provided…
Being a transmigrator is too good, isn’t it?
This is paradise for homebodies!
***
The day Selene became a transmigrator,
in the Imperial Palace’s conference room, the main figures from the original story gathered.
“The protagonist from the oracle has arrived.
To seal the Demon King, we absolutely need this person.”
After Crown Prince Noelle’s solemn declaration, all eyes turned to Grand Duke Sirinu.
“Demon King or whatever, I’ll kill it.
You all just make sure to take care of that precious person, and don’t let her run away.”
Sirinu walked out of the conference room after saying it coldly.
Everyone in the room had the same thought.
‘I must find her before anyone else does!’
Thus begins a fierce contest to win over the homebody Selene’s favor!
