A new arc begins in Boruto: Naruto Next Generations in this month of August 2017.
It cover the contents of Naruto creator Masashi Kishimoto’s Naruto Gaiden: The Seventh Hokage and the Scarlet Spring.
The Naruto Gaiden manga was a total of 10 chapters long.
By September 6 with episode 23, we’d venture to guess it will be another two chapters for nine of the ten chapters from the Naruto Gaiden manga covered.
