"Reference and Setting Guide" Naruto

Are Obito and Shisui real brothers? AB didn't say that @@ PS. Such a complete information setting is really appreciated, thank you very much

I came here through many links. . . Thank you for your hard work. It's not easy to sort out so much information. Touch it. By the way, my reference for information is AB's XXX book on Combat Fighters. The text version is indeed better than the pictures.
