Samurai

Once a month, I post a Gattai, and usually each grid has a separate constraint. This month, five grids, a full Samurai Sudoku, but they are all classic Sudoku, with diagonal lines the only extra rule. This title is redundant, since 侍 is the character for “Samurai,” making the title “Samurai Samurai Samurai.”

It may seem like a lot of constraints, but it's a Samurai Sudoku, so you should only have deal with one or two at a time.
