Yomi/Plot

B-Rank Wars Arc
Yomi is an agent from Galopoula under Gatlin, sent to cause mayhem such that Border could not send retaliation and recovery forces against Aftokrator. He first appears when he scouts the area of a recent fight between Katori Squad and a few Trion soldiers. During the blitz, he monitors Koskero, Reghindetz and the Dogs. He joins the fray by controlling two Idras in Manual Mode, flanking the Gunners. He is intercepted by Sasamori, whom he manages to wound, and Kuroe. He engages Sasamori and Tsuji with one of the two Idras, and Kuroe and Kitora with the other. Although the latter two defeat it almost immediately with a combination of Spider and Idaten, he immediately takes control of another Idra. Thanks to Amō's Side Effect, he is instantly located and targeted by Kitora and Kuroe. However, having understood the mechanics of Idaten, Yomi manages to counter Kuroe's attack, wounding her in the process.

Following Gatlin and Rata's defeat, he orders the Trion Soldiers to retreat. Back on the ship, he analyzes Vasilissa's broken arm, concluding the fracture was due to the overlapping of two attacks.
