At the blue oni's house, the door was shut tight, and a note was affixed to it.
Please enjoy yourselves living a friendly life with the humans.
And please take care of Shiro.
She is my precious only daughter.
Aka, you are the one that I can entrust with this.
If I were to remain here together with you, it is possible that you might be thought to be a bad oni.
I will be making a journey from now on.
I will never, ever, forget you all.
Even parted from each other, we are family.
And her tears flowed freely...
The red oni silently read it over countless times...
The red oni was unable to move a muscle from the spot until it became dark...
After the red oni finished reading it, the white oni started to bawl her eyes out.
And on that note, these words were written.
