At present, only KANON AIR CLANNAD has changed the painting. Animation books are usually written from the perspective of animation.
The crux of the matter is that ONE is not made by key, and there are only two ova in one's animation. It seems that one OVA is 18X, and the other is full age.
One was only created by the original team of Key Club at that time, but it was not the first work of Key Club. It's just that the fans of the key club habitually integrate one into the game of the key club.
Therefore, the reason why comic books are generally not written is that there is no animation and it is not the key object. It's that simple.
