Kitamura Eri is known to draw very well. But young Yuuki Aoi seems to be no slouch herself.
In her blog, Yuuki (she likes to call herself by her slightly unusual surname) posted a picture of a little panda figure that her father brought back from a business trip to China, and put beside it a drawing she made of the panda as a boy about 12-13:
Then she posted a couple of drawings that Kitamura Eri had done: one of Yuuki herself (left), and one of Yuuki as Mina in Dance in the Vampire Bund:
Yuuki and KitaEri act together in Vampire Bund and Yumeiro Patissiere, in both of which Yuuki stars. I think that 17-year-old Yuuki is excellent in both, especially in Vampire Bund. KitaEri is just 22, but is already a veteran seiyuu and has become very successful in the past couple of years, ranking among the top twenty seiyuus in terms of episodes acted in last year.
To tell the truth, I think that Yuuki's drawing of the panda-boy looks a bit like Sawashiro Miyuki, with whom Yuuki starred in Kurenai. The words on Eri's drawing of Yuuki say: Aa-chan." Even though Yuuki-san refers to herself as "Yuuki," most other people call her variants of "Aoi-chan."
