According to the credits in the music video's description, this piece was drawn by an artist named "DENN." Unfortunately that name is incredibly ambiguous and 9Lana never linked to any of DENN's accounts so I haven't had any luck finding any links for them.

artist #200344 is a strong web search result for "DENN イラスト" and posted this picture on twitter. Artstyle looks similar as well. I think it's a strong enough case that I added the tag.
