Mune-mune and Kuramori
Mune-Mune in "Abenobashi mahô shôtengai" (2002) and Kuramori in "Haibane Renmei" (2002) sure look like they are related. The oil painting of Kuramori could just as well have been of Mune-mune.
I noticed it easily, since I was watching both shows in parallell.
The real-world relation between the two characters, is that they share the same Japanese voice actress, Aya Hisakawa.
Anybody know wether this face appears in other shows, and wether it has anything to do with the voice actress?
