Carcano M1891 made a flashy entrance in Chapter 10-6, leading her team as Griffin reinforcements when AR Team was pinned down after being ambushed by Sangvis troops under Judge's command. She introduced herself and her sister, RF Carcano M91∕38Carcano M91∕38 , under the names Cano and Ceno, and filled the AR Team in about the Commander's current situation. The Commander had made contact with Sangvis units, and had made an attempt to force a gap on the encirclement, yet Judge and her troops were proven to be too strong. Cano's delegated her team to hold the enemy back in order to let AR Team escape the encirclement through the gap. Suddenly, AR M4A1M4A1 lost consciousness, and SMG RO635RO635 told Cano to hold the line while she evacuated M4A1 to a nearby building.
Some time later, Judge herself showed up in her search for M4A1. Sangvis troops pressed the attack, and Cano's squad was forced to fall back to regroup. Cano told her wounded sister to take a rest and see if anyone answered their distress signal. No answer was recieved, but Ceno had detected that the army's signal was approaching their position. Under the heavy fire, AR M4 SOPMOD IIM4 SOPMOD II apologized to Cano's squad that they were caught in this situation, but Cano answered back that it was an honour for her.
Ceno soon received comms from the Commander informing them that their reinforcements managed to broke through the encirclement, and would arrive in 10 minutes. The Commander instructed them to hold on until then. By now, SOPMOD II had gone into frenzy, tearing Sangvis units apart left and right. As Judge was ready to launch an EMP attack, Cano saw a chance in that very moment. She asked SOPMOD II to provide cover for her, and bet everything in a single shot. Right before she could shoot, the Dolls were blown away by an enormous explosion. Knowing the army has arrived, the heavily wounded Judge and the remainder of her troops made a retreat.
The remaining of Griffin dolls were relieved at the sight, thinking that they had been saved by their KCCO allies. But that could not have been further from the truth. Captain Yegor promptly ordered his men to kill every Doll present, before walking onwards to his true objective where RO and M4A1 were held up. Standing no chance against Military-grade Arms and caught utterly by surprise, Cano, Ceno and the remainder of their squad were among the first casualties of a devastating and bloody betrayal.
