The reason was very simple, the Blood Spear suddenly came to a stop right in front of Roan! Roan didn't do anything.
*Sphhhlt!*
Suddenly, a black sword pierced through Granto's heart, full of Light and Fire Element.
Roan only snorted when he saw that, though. He then looked at the shocked expression on Granto's face before telling him through a Divine Sense message. 'Idiot. Did you forget I'm not alone?'
'Life Fire, Fourth Forth, Light Piercing Bomb!'
*Boom!*
Rean's attack caught Granto by surprise, who held his destroyed torso. Granto could only turn his head before seeing a white-haired man look at him with pity. He bitterly smiled before his world went dark forever, just like Hedoi and Kluo.
Rean then looked at Roan and said, 'See? I told you he would forget I existed.'
