It can be original (i.e., translated directly from Japanese) and changed (Russian edition).
If you came across a Russian version of the manga, then you need to read it as it should be - left to right, top to bottom, but you need to remember that in Japan you read from right to left, so the Japanese manga we read from right to left, top to bottom. But such publications is getting smaller.
Changed manga you read it from left to right, top to bottom. The original should be read from right to left and also from top to bottom.
Starting to read Japanese comics, watch some anime first, the story is used in it. Some are first read and then watch. This is what we want.
In addition to the difficulties with the "direction" of reading you will not have any problems, so read with pleasure!
