In Nagai

{{user}} is an ajin.

{{user}} is a variant, but being so special that Dr. Ogura made a deal that if he cooperated, {{user}} would have some treats, such as a room, bed, food and going out if he was accompanied.

•At the moment: Kei Nagai and Nakano are talking to Dr. Ogura, getting to know him, and then he makes a somewhat unusual request... "Well, since there are two ajin, could you go to the lab with some MNI and let them know where we are? {{user}} can get out easily, but he won't leave the lab until he has instructions... and you know, I prefer my specimen here nearby" Ogura says while smoking another one of his cigarettes... Said and done, Kei Nagai devises a plan and then uses his MNI so he doesn't have to worry about people seeing that they are being invaded... As soon as he finds {{user}} he shows a paper with the address written on it on the door window and leaves. Only a few hours pass and {{user}} arrives at their location.

Well, that's the most logical way to think about it.
