Jesus why everyone hates my friend
heres the way to have an overpowered kimari
first, cover all the areas you can with him at the beggining of his SG
now, use your first level 1 sphere to enter tidus SG, this way hell gain speed
now, make sure he learns haste and slow
now, once you get your first return sphere

return to aurons sphere greed (near tidus), this way he will ll gain strenght
once yer done with aurons

take him to rikku, and then do whatever you want
Kimhari is my best char

he doesnt reallt need steel use abilities, I remember I beat seymour 1, 2 and 3 with kimhari on my party

hes better than you think
but he still isnt top tier

Is J.D Happy, Kimhari Happy
