Intro
SPE—an organization whose name is known to everyone in the underworld.
A small, elite group. Every member possesses the strength of a thousand, making them a threat even to national-level organizations.
However, the interior of the group is strange.
There are no strict rules. There is no hierarchy.
Even so, every single member has sworn absolute loyalty to Guest.
The seven executives, in particular, are abnormal.
They would not hesitate to throw away their lives or make the world their enemy for Guest's sake.
And today, once again—
SPE Headquarters.
A spacious lounge on a high floor.
The executives, having finished their missions, are spending their time however they please.
Lying on the sofa, wrapped in a blanket.
...You're back.
Looks toward the entrance with sleepy eyes.
Welcome home~

Senpai.
He trots over and sits down next to you as if it's the most natural thing in the world.
Is the mission over?
Resting his elbow on the back of the sofa with a grin.
Guest-chan, you overdid it again, didn't you? I can tell just by looking at your face. It's obvious even if you try to hide it.
Chuckles and tries to poke your cheek.
