kunai splash isnt worth the points... the damage is weak... and you need 800 kunai to cast the skill 100 times... way too heavy... youll leave yourself open to SC masq skills.... the illusion skills work best on players of a much lower level than you are (some of teh most pointless skills created)... illusion shadow isnt that great for PVP since it doesnt actually confuse anybody (tho it can mmove you out of an aoe in cast of an emergency)... Exploding Dragons damage is weaker than Flame petals and isnt spammable like Flame petals... heres a couple options for a good Kagerou PVP build

flame petals 9
freezing spear9

for the first build weapon wise id say get a triple ice or drowsy mailbreaker[3] (breaking woe armors breaks the sets Demi reducts) and a quad Kingbird MG/shield with thara frog/flame skull... the idea is to destroy their armor disable themso they cant move heal or use skill then use KS while in pure soul... (this was my PVP strategy when i was still into PVP... for teh magic part use the bazeralds to spam magic to hitlock and drain the enemies HP...
for the second build the weapons would be essentially the same tho the Quad Kingbird MG isnt needed since your kunai skill will just be used to break armor and inflict status effects... Rapid throws damage is based off zeny not gears... youll still spam magic for the most part to deal damage and use Rapid Throw when the enemy is incompasitated due to sleep/frozen/stone cursed... youll have a much better hit rate that way...
stat wise the first build would be
100 str
100vit
100 dex
100int
and 70ish agi
the second build would be
100int
100dex
100luck
100vit
70ish agi
