Another rare Nikoli type. Paint some empty cells black. Black cells strictly form squares. Unpainted cells are orthogonally contiguous. Clue cells share side(s) with at least one painted square. If the clue contains a number, that is the total area of orthogonally adjacent black squares. (Rules, example here)

Was always too lazy to look for English rules for these, but seems to be a fun puzzle type, and I thank you for the easy introduction to the type.
Nice puzzle type.
