What are the details of these novels? When Are they coming out? separate releases from Shonen Jump? Written by kishi? Accompanied with art?
I'm just interested in the shikamaru one!
There is going to be six light novels in total.
Kakashi - February (already out)
Shikamaru - March (already out)
Sakura - April (coming out next week) was supposed to be June but got pushed early
Garaa -May
Akatsuki -June
Konoha -July
Is the order they are supposed to be released in, but it could change as it did with them pushing Sakura's novel earlier from June to April.
The light novels are not published in Shonen Jump (in fact, I don't even think Shonen Jump ever serialised novelisation before, not even as a preview. Though the English one was asked if they could on one of their podcast episodes about it).
Kishimoto himself is not writing them, however he is supervising the different writers and approving them as part of the manga canon a la The Last.
There are some illustration included, being light novels, but it's not much. The Sakura one might have some "interesting" looking ones though.
