No one actually has a demon lord form, actually. But Rimuru actually does evolve, from a normal (unique) smile, to a demon slime. His slime body should be a bit bigger than before, which in turn makes him look alder in his human form by 2-3 years but i think it's not obvious in the manga hmmmm
Yeah I watched the anime too
Haven't watch season 2 yet. Did he look older though. Well it doesn't matter but
Spoiler!!

If the last evolution doesn't make him look like a goddess I will feel cheated ಠಗಠ
Well he's hair looked amazing. It was all glowy and stuff
yeah he grew taller in the season 2 after he became a demon lord. based on the LN, in the beginning he looked 10 years old, but after he became a demon lord, he became 16 years old in body
Does rimuru have a demon Lord form though
