Seto felt uneasy with the seeping darkness of Yami. Seto felt his determination grow when looking to Ishizu who now was at the man's side and a knife held to her neck 
"I wouldn't if I were you. If you want to leave, you might as well wait because you are sadly mistaken if I let you leave with a knife at a woman's neck." Seto smirked with his most confident and nonchalant tone. Yami on the other hand had seemed to have enough of this as his spellcasters went for the attack, their summoner having played a few other cards like Spell Power Grasp and Mage Power of which getting some power boosts to Cerberus and Breaker, raising their power from 600 to one thousand. Working easy to take out those monsters.
