I really like their work. Her and Yuka Morii are probably my favorite illustrators. Adachi hasn't had any new card illustrations in about 6 years. Before that it was Palpitoad in 2013! (Spinarak was a reprint).
I can't find much online either. The top hits for her name are serebii.net, pkmncards.com, and other card sites, which don't give much detail outside of existing cards.
I did find https://www.gallerymitsuido.com/sachiko-adachi/ which kind of implies she retired in 1993. Or it's another artist. Dates don't really work for Pokémon, so I'm not entirely sure.
Anyone have some more info?
