The 1st question to Kishimoto & Ikemoto was :
“You worked together for a long time, since the beginning of NARUTO, now you work on BORUTO how you guys manage it, does the dynamic changed?”
Kishimoto : “for NARUTO and BORUTO it’s completely different, during NARUTO I wrote and draw the story and Ikemoto, back then, was my assistant, he did mostly the background and a lot of clones” *laugh*
“On BORUTO, Ikemoto is the one that write and draw the story, that’s the difference”.
