The first and most current three chapters are free to view on Viz media, but as with anything it's best to support it by buying the content because it's amazing, and it is probably challenging to create more of something if no one is buying it XD
It's real good news that the manga is available, and translated officially as well! Arguably nicer than unofficial translations, and where the artwork may not be what it should be. Who settles for stones when there are diamonds available, eh.
