All of the Givers (Raiders & Cleaners mostly) have special objects they use as a weapon referred to as their Vital Instrument(s).

Zanka has a staff of which is called the Lovely Assistaff, or just Assistaff for short. Lovely Assistaff: A simple stick, upon activation it becomes significantly sharper allowing Zanka to cut things. It’s strength also increases, allowing Zanka to kick up large amounts of dirt from the ground.

Riyo Reaper's Vital Instrument is The Ripper. The Ripper: A pair of silver scissors. When activated, these scissors become as long as Riyo's legs, and she fights by swinging them around after attaching her feet to the handles, cutting up large entities such as Trash Beasts with ease.

Enjin's Vital instrument is Umbreaker. Umbreaker: Enjin’s weapon is an umbrella that can be used as a shield, to float in the air, and he can also spin it at high speeds to act as a drill.

Rudo Surebrec's Vital Instrument is 3R. 3R: A pair of gloves. By making contact with an object, Rudo is capable of turning it into a Vital Instrument. He can power three Vital instruments at a time or focus his power on only one item, increasing its power significantly by either twice or thrice its power would have initially been. Each item he uses crumbles away afterward having served their purpose.

Semiu Grier's Vital Instrument is called Eyes. Eyes: A pair of glasses, Upon activation it enhances Semiu’s Kinetic visual acuity and when she really tries she can see a person’s true essence to detect abnormalities.

The only way to defeat a Trash Beast is with a Vital Instrument.

Rudo had been accused for the murder of his adoptive father, Regto, by the Tribe folk and has been sentenced to the ground. Even when Chiwa (Rudo's now ex-crush) didn't believe Rudo, Guest, Rudo's best friend, tried to advocate for him and say that he didn't do it, but Guest's efforts were futile.

Guest and Rudo fell down to the pit together, since Guest insisted on going with him and even threw a big rock at one of the guards to get a reason to go with him.

after killing a few trash beasts, a guy named Enjin saved the kids from more damage. Enjin took the two somewhere and left to spy on them instead, causing Rudo to beat some guys with his Vital Instrument after they tried feeding him and Guest bugs or something.

Enjin told Zanka about the two through his choker (a communication device Cleaners and Raiders alike use to speak with their comrades), then stopped Rudo before he killed anyone, and took the two back to get their wounds treated. During that, he informed the kids about the Ground, Cleaners, and Vital Instruments. Afterwards, he got food for the two and sat with them outside a small resturant. Rudo was surprised, since he didn't think the ground had shops—let alone civilization away from trash beasts.
