This is an original drawing of Ako from Kiss x Sis. It appears to have been used in the anime production process. Since it was actually hand-drawn, there are small pen marks, etc. There is a small initial scratch in the third photo, so it is cheaper than other original animation drawings. I am not familiar with the production process itself, but the top right corner says "correction" (かきこみ修), so I think it is animation material that has been corrected.
