Kakko Fubatsu

The Denjin Renki (電刃練気) is Ryu's second V-Trigger in ''Street Fighter V. ''

Description
When activated, Kakko Fubatsu energizes Ryu's fists. This gives him access a special counter called Isshin. Upon countering an attack, a shockwave of energy will be released around Ryu. If this shockwave hits the opponent, Ryu will perform a strike attack, causing them to crumble and allowing Ryu to follow-up with an attack. Using Isshin, Ryu can counter everything except throws, giving him a highly functional defensive option. The opponent will be vulnerable to additional attacks after the Isshin strike, making for a great opportunity to deal major damage.
