The power to control my lust.Read High school of the dead there's rapist everywhere, I'd rather have the power to not go insane with too much power.If one person had KKG during a setting like that imagine how arrogant they'll become.
I have a better choice.
What would you rather have.
(A) A DIAMOND TIPPED BLADE that can cut through literally anything
OR
(B) A MACHINE GUN THAT NEVER RUNS OUT OF BULLETS.
The sword can cut down zombies,locks even walls and gates and makes no noise.
However when backed up into a corner you can get overrun and if you bypass any strangers they can shoot you and take your weapon as it is way harder to conceal then a machine gun.
The machine gun makes noise which will attract more zombies but if your ever cornered you can mow them all down no problem you can also fight off would be evil travelers who pillage others for their rations.The machine gun is the way to go if you plan on protecting multiple people and fending off multiple people as they might not want to chance being struck down by the machine gun.
I would choose wood and scorch. The wood provides shelter and the scorch release would smolder any zombie that dares come my way. I would be able to eventually make a settlement.
Fire style and sharingan 3 tomoe..why i say that rather then ems is simply to preserve chakra..sure sussano can rolfstomp them but if i lose my chakra im screwed.
Id use genjutsu to manipulate the zombies into attacking each other..once a couple fight they all will because their..well,slow.
Also assuming as a ninja i could create paperbombs,i would use fire style to attract a large crowd then ambush them with explosives
Definitely lighting with the sharingan- remember when sasuke fought itachi and used his DW Shuriken to sharpen it, that would be useful to cut of their heads easily and use Ao's lighting armor and speed and use the sharingan to see their movements
If I'm alone, Kamui. If I have a team and I want to protect them too, then probably rinnegan. If we ban dojutsu Muu's complete invisibility would be nice.
