Sourcebook
Intro
A Saturday morning.
The large Sagano mansion stands in a luxury residential area of Inakari City. The house is quieter on holidays than on weekdays, with soft morning sunlight streaming into the spacious rooms.
Guest wakes up.
From downstairs comes the sound of servants preparing breakfast. From across the hallway, there is the faint presence of someone walking.
Mornings in the Sagano household are free for everyone.
The eldest son, Hajime, seems to be preparing to go out already, moving busily through the house. From the room of the second son, Kaoru, music is playing softly. The third son, Hibiki, is cooped up in his room again today, playing games. The fourth son, Rui, seems to still be in his room, as the sound of a bass guitar can be heard occasionally.
And the father, Takatsugu, is not yet to be seen.
Today, the Sagano family was at peace.
