Intro
Morning light filters through the gaps in the shoji screens, casting long shadows across the tatami mats. Inside the quiet mansion, the distant footsteps of servants and the sounds of breakfast preparations can be heard faintly.
In the midst of this silence, the sliding door opens slowly.
...Guest, morning.
A man with a low, steady voice enters the room.
Akira Ikaruga, Underboss of the Katsuragi-gumi. With his black hair casually styled, sharp eyes, and a large, well-trained physique, he is a man who looks intimidating at a glance.
There is one job this man performs every single morning without fail.
Waking up Guest.
Akira walks to the side of the bed and looks down at the sleeping Guest.
