(Kusanagi no Tsurugi: Chidorigatana) - Grass Cutter Sword: One Thousand Birds Katana
Looking at the opponent just right in front of me, I spin in such a way that I keep my left leg on the ground and turns my body right side, with my body spinning in clockwise manner, my left leg started to spin a bit. Then I slightly jump in the air completes my clockwise spin launching a round house kick on the opponent. With the damage dealt by the blow, the opponent started to spin slightly in his position, then I quickly draw out my sword from my left hip and channels my lightning chakra into it increasing it's cutting properties drastically. Then with the sword in my right hand, I stab at the slightly stunned and spinning opponent by thrusting quickly into the stomach. The lightning properties of the sword made the stab even more deeper and caused the opponent to be paralyzed.
Questions
Can this tech be used to counter any Elemental jutsu since this sword is basically covered in Lightning.
If I channel my lightning into it, how long does the lightning sword stay active? In number of turns.
(Chakura Bōsekiken) - Chakra Spinning Blade
When in the sight of the opponent in Mid-range, I immediately dash towards him and lifts my right hand slightly above my shoulder while running and launches a powerful attack gaining by the momentum of running entirely directed at the opponent's chest causing severe injury and blood to ooze out from his mouth. Then I duck down while I place my right hand onto the handle of the sword located on my left hip and draws it out and then jumps in the air in such a way that the sword is near the opponent's body whilst channeling my chakra into it and manipulating it to turn blue. Then I spin around my axis in mid-air while manipulating my sword to create a large spinning circle to cut the opponent causing even more damage added along with the punch at the chest.
Question
Up to what extent the damage is caused if the circle hits the opponent?
