Generally, even if characters are way older or younger than they appear, they always have the general appearance of their represented Vocaloid/Utau/whatever (I think the only difference between typical Len and Len mothy characters is the lack of spiky hair for a canon design). Considering that, I'm leaning slightly more on trivia since Arth's design was specifically made with an adult look in mind, rather than just a Len look.
