I just thought of a "reason" why the root attack happened, as the new identity got the The Sword of the Thunder God and Kiba could you just make that he attacked cause he is finding sakumo's sword The White Light Chakra Sabre in most FF said sword is cable of producing white lightning. Or you could just add The White Light Chakra Sabre as another sword for fujin's collection.
I hope that Fujin will consider improve his Jutsu arsenal by learning: Water-Release, Yang-Release & Medical Ninjutsu. I hope that Fujin uses his Shadow-Clone Technique to learn these Jutsus:- (1) Hiding in Mist (D-Rank) (2) Temporary Paralysis (D-Rank) (3) Wild Water Wave (C-Rank) (4) Water Prison (C-Rank) (5) Water Bullet (C-Rank) (6) Water-Clone (C-Rank) (7) Water Gunshot (C-Rank) (8) Exploding Water Wave (B-Rank) (9) Water Dragon Bullet (B-Rank) (10) Water Fang Bullet (B-Rank) (11) Water Wall Formation (B-Rank) (12) Delicate Illness Extraction (B-Rank) (13) Poison Mist (B-Rank) (14) Regenerative Healing (A-Rank) (15) Hiding with Camaflogue (A-Rank) (16) Four Legged (Yang) (D-Rank) (17) Soft Physique Modification (D-Rank) Yang (18) Claw Extension (C-Rank) (19) Hair Binding (C-Rank) (20) Hair Needle (C-Rank) (21) Wild Lion's Mane (B-Rank) (22) Needle Jizo (B-Rank) (23) Transparent Escape Technique (C-Rank) (24) Earth Shadow Clone (A-Rank)
