You see hints of the normal Venus, usually if she's just with Artemis; he brings it out in her a bit more. Then at the end before she dies, she leaves the girl a long letter, and it mentions that she found her 'true self' once she finally moved on from all this MISSION MISSION MISSION. I've always assumed the 'true self' is the animanga-ish side of her that still teased Artemis, played practical jokes on him, ate cakes with Usagi, etc.

Really tho, if you don't shut me up, I'm going to keep spouting about PGSM all day. XD
