There's this one-page mini manga chapter for this series about this fox girl and her family. I'm having trouble reading the kanji word in the lower left panel that's written below where the two troublemakers have been caught.
「姉？？は大罪じゃ」
I'm having trouble finding the two kanji marked with question marks. My efforts to search them by radical has been fruitless since I can't make them out too well. Any help with this would be appreciated!
