- Nex and Akuhei have an extremely hateful tie, Nex calls him a "Sequence Destroyer" as Akuhei isn't simply a General of the NOS but also a member of the Intelligence group guarding the "Truth" called the Sequence Intelligence Agency. Akuhei mentions he hadn't seen him in years, inclining that he and Nex have a history together.
- Akuhei has a strange capability that allows him to read into Nex's thoughts and feelings, why he has this connection to him isn't known, but he uses it to mess with his head. He exposes that Nex does actually care about some things, he just refuses to show it for reasons of being afraid of some negative side effect or having it be used against him. He also mentioned that Nex's grimoire has likely made it impossible for him to see anything good in the world or in himself even pointed out how the two were hardly different.
- He easily crushes Nex, after he tries to combat him and kills the one who was aiding him. Oddly Akuhei is capable of consuming pieces of siethr and soul energy, which he did so to the one he killed though why he would do it isn't known
- Observers were specifically hunted down during something called "The Purge". Legna is one of the few to remain and has been aiding Nex, though none of it is to Akuhei's surprise. The two seem to know about each other as indicated in their dialogue when Legna gets Nex and Myri away from Akuhei.
