How do I read manga with multiple panels?
You would typically read it in a S shape from one row to the next, always returning far right panel when you start a new row.

+-------------------+
|    2    |   1     |
+-------------------+
|  6  | 5 | 4 |  3  |
+-------------------+
|    8    |    7    |
+-------------------+


So on the first row, start from the far right and you hit the far left panel of the first row, move to the far right panel of the second row. Then at the far left panel of the second row, move onto the far right of third row and finish the page.

However because of the flow of action in this particular page the order of panels goes more like this:

+-------------------+
|    2    |   1     |
+-------------------+
|  3  | 4 | 4 |  3  |  &lt;-- the 2nd and the 4th Hokage are acting simultaneously
+-------------------+
|    6    |    5    |
+-------------------+
