Kikuchihara's Side Effect is revealed; enhanced hearing. While it wasn't revered at first, Kazama saw this as a potential asset to his team. Along with the then-operator, Shiori Usami, they become powerful. However, Enedra reveals that he possesses a Black Trigger, and easily defeats Kazama.
Two years ago, Kikuchihara's Side Effect of enhanced hearing was deemed a low-class Side Effect. Many condemned it as plain, and Kikuchihara agreed. However, Kazama, 19 at the time, sees potential in this Side Effect, and offers him to join Kazama Unit. Usami explains that the auditory information made a better analysis of the situation than visual information. Through winning battles, Kazama Unit becomes a feared force, as well as Kikuchihara's Side Effect becoming more respected.
Enedra expresses impatience with the team's constant dodging of his ability, and decides to go at "full-power". However, Kazama, using Chameleon, sneaks up behind him and attacks him. While Enedra seems to be decapitated, his body suddenly reforms, and Kazama begins to cough up trion. Mikami tries to explain this as something from within the Trion Body, and Enedra reveals he has a Black Trigger. He then finishes off Kazama, preparing to attack Utagawa and Kikuchihara.
