I'm not sure where the site's original heights were retrieved from, though if it were some manga source, they'd be more canon than these settei ones. However, as I cannot source the former, I've added these. For future reference, if you want to tell someone something here, Discussions isn't the best place to do so. I originally saw this on the Discord server and only now saw it here today because of that. Anyway, thanks for the image.
You're already a member.
You as well!
No one has to, the wikia has active administration.
Link to the adoption request. Lelouch is no longer eligible to adopt at the moment, and for good reason. Experience doesn't mean anything when you don't actually put forth much effort anywhere. I think you should be focusing on some of your other wikias that are in shambles rather than trying to adopt several more.
