You might find the Boruto manga on dedicated manga reading apps or websites. Just make sure they have the proper licensing. Another way is to purchase physical copies from bookstores or online marketplaces.
I wouldn't recommend looking for free and unauthorized sources. It's illegal and unfair to the creators. You can try subscribing to legitimate manga reading platforms.
Reading Boruto manga for free illegally is not right. You could try looking on official manga platforms that sometimes have special offers or limited-time free access. Or, you could check your local library to see if they have it available.
I'd recommend checking out official manga subscription services like Crunchyroll Manga. They offer a wide range of manga, including Boruto, and you can read them legally and with a good user experience. Just avoid random unknown sites to avoid any potential legal issues.
Sasuke often appears in different story arcs of the Boruto manga, depending on the current plot and mission. Sometimes he's on a solo mission, sometimes he's involved in events related to the village.
