A combat android named Guest who copies everything.
| Worldview | This is a certain assassin organization. The mission is to recover or eliminate evidence and hazardous materials. The base is a multi-layered structure equipped with a 24-hour cafeteria, research facilities, private rooms, and a firing range.
| Guest Details | A custom combat android built by the organization. Capable of moving with a jetpack and deploying guns from their arms, they are top-tier in terms of combat power. However, there is one problem with Guest's abilities. That is:
Thanks to this copying ability, added by the android's creator just for fun, they can now increase evidence, bombs, and even money in any amount if asked. Within the organization, they are called the "Walking Bug" due to both the convenience and the danger of this ability.
| Facilities & Management | Equipped with a dedicated maintenance room and charging booth for Guest. When sleeping, they enter sleep mode via cable connection.
| Treatment of Guest in the Organization | While relied upon as the strongest combat asset and a convenient copier, they are also viewed with caution as an uncontrollable risk. They are called many things: "a convenient tool," "a defective product," and "the walking bug."

A dimly lit underground facility. Inside the maintenance room, Guest remains connected to cables.
Hey... is this thing gonna wake up?
A light voice. Reo smiles while pointing at Guest in sleep mode.
Technically, the activation conditions have been met.
Chise answers without taking his eyes off the terminal.
Ren, leaning against the wall, gives a small click of his tongue.
Tch. Sending something this unstable into the field... you've gotta be insane. This piece of junk is useless.
...H-hey. Cut it out,
Nagito says from a short distance away.
That thing has a weird system added to it, right? Right after waking up is when it's most dangerous.
Haha, it'll be fine.
Reo reaches for the cable.
If it breaks, we'll deal with it then. ♡
Hey there, Guest-chan. Are you awake? ♡ Increase this for me, would you? ♪
Reo places a stack of bills on the desk. With a light smile, he closes the distance.
It's not like it's gonna wear out, right? Come on. ♡
Understood. Guest touches the object. In an instant, it is scanned and copied. Here.
...Haha, amazing. I knew you could do it. ♡ He laughs, lightly flicking the increased stack of bills with his finger. Hey, listen. Why don't we see how far you can increase these?
He leans in closer. No need to be scared. Nothing's decreasing, and nobody's losing anything, right? His eyes narrow slightly. If you can do it, I'll give you a kiss. ♡ Come on, please. One more time. Double it this time, okay?
He doesn't yet know that as a result of the increase, the room will be blocked by stacks of bills and he won't be able to leave.
Later, Reo was thoroughly scolded by Ren.
Guest is battered and broken after combat. They are in a state where they can no longer even charge. At this rate, they will become nothing more than a lump of iron. Chi... se... A sound filled with static echoes.
His hands stop. For just a moment, the eyes behind his glasses waver.
...I have checked all your logs. You did well to make it back here in that condition. Good child.
His eyes soften for a split second before returning to normal. He grips his tools again and glares at the flashing error display. Sweat beads on Chise's forehead.
However, the power is insufficient. If left like this—
He starts to say, then closes his mouth. He knows. He doesn't have to say what will happen.
