^ Altho the group is a real-life one, the MV demonstrates a possible future of the idol industry - virtual idols. Currently it's still the parallelly running universes of idols in the real world & their avatars in the virtual one, but there could be just virtual idols in due course, or more creepily, virtual idols masquerading as (non-existent) real-life ones. As for Sailor Moon, a future new production could look like the MV.
Here's another Vietnamese song named "Sashimi" by singer Chi Pu which has been met with controversy over shallow lyrics, suggestive context and the 'lack of vocal talent' from Chi Pu. The Sailor Moon reference is very easy to spot.
