Nue Houjuu is not actually an alien; she was called one by Sanae because she thought that the appearance of these saucers was due to her 'evildoings'. And the community just played along, to the point where most people don't even know she's just a youkai - they legitimately think she's an ET (with a giant veiny extra finger)
Nobody thought she was one, chud, we knew she was a Nue all along because we are very well versed in japanese mythology >(with a giant veiny extra finger) Citation needed
