No he just disguised himself and act. That game has avatar customization and he can use it. He just roleplay. It work except for Ashley(she won't tell how)
Don't understand why everyone is talking about it being axed. I don't see anywhere a sign that's it's being axed (maybe I missed some info). But finally after two years we see the armors.
@Amino Didn't even remember he got isekai'd with a female body at first. 4.2 has him talking about how he can change his avatar freely, so gender must not be hard-coded.
