Two Black Triggers

Long Summary
Flashback Start at Dr. Lamia's lab, Lamia is debriefing Giev about what Lilith is. She then orders Giev to bring back as she ran away with Xeno, and "reminds him" that Xeno brought upon his downfall by using dirty tricks.

She finishes off by saying her body must be brought back dead or alive, while Xeno must be killed as to prevent information from being spread to other nations.

Flashback End Yūma expresses his surprise at how Giev has a Black Trigger the entire time, while Giev comments on how a trump card works best when you're not expecting it.

Charon tells Giev that Xeno and co are running around the rock quarry, however Giev says it is not an issue as he made arrangements for them, and he'll take his time dealing with them after he takes care of Yūma.

Yūma tells Giev that he won't go down so easily after hearing that. Giev smirks at that, and summons a new trion soldier, Scare, and tells Yūma that Trion Soldiers that are summoned through his Black Trigger are several times stronger so they won't fall so easily.

the Scare lungs at Yūma and was able to graze his shoulder, and Yūma himself thinks about how it is fast so it must be special. Giev asks Yūma if he understands what he meant, and then tells him to die, and then summons more Scares.

Yūma thinks how they are about as fast as him, and before he can finish, the Scares shoot at him with red Trion Cubes, but Yūma either dodges or blocks them all, and finishes his thought: they don't constantly attack, they adjust their distance and cooperate.

Charon comments that Yūma is quite tough, but it should be draining to use that black trigger without help. Giev understands and orders the Scares to vary their attacks, while Yūma thinks about how they "figured out his weakness already", so he'll have to see how many Scares he can beat without Replica.

Osamu, Chika, and Xeno all move through the hallways of the quarry in search of Yūma. Osamu asks if Yūma is actually here, and Chika confirms it, and mentions that 3 of their seniors are on their way. Xeno says they should just leave already, Osamu goes along with it, but mentions how he wants to get his trigger back before they leave, Xeno asks if he actually knows where it is at, Osamu says he does assuming Giev doesn't have it.

The group was able to find Osamu's trigger, Osamu is worried if he doesn't have enough trion to summon a trion body, but attempts to activate the trigger anyways; he succeeds however he doesn't have enough trion to make a weapon. Xeno insults him, and then guesses that he'll have to handle all the fighting, to which Osamu confirms, and apologizes, Xeno says he is as docile as ever, and says "if you're a man, be a little more stubborn."
