jiraiya toad barrier DOES NOT BLOCK barrier skill

if u read closely the skill description, jiraiya toad barrier BLOCK any ninja with the ability to summon/destroy barrier from casting MYSTERY skills

example:

minato edo can cast bond skill barrier - his mystery will be blocked (even the bond skill still not activated)

kisame shark can cast barrier through mystery - his mystery will be blocked

madara edo can cast barrier through passive (either every round or when Hp at certain %) - his mystery will be blocked

i hope this info helps :)
