No. Hes dueling with Zero life.
[spoiler]He let that machine gun Ogre hit him with its effect, effectively reducing him to 0. However, he had an ace up his sleeve, Infernity Zero. It's special effect is as follows. When he is reduced to 0, he discards all cards in his hand except Zero, and special summons it in defense position. As long as its on the field, he cannot lose even if he reaches 0 life points. When he takes damage in intervals of 500 though, 1 death counter is accumulated. When there are 3, Infernity 0 is destroyed, and he loses.
He played that, and then when Lotten was about to fire more rounds, Infernity Death Gunman points a gun to Lotten's head. When kiryu has 0 cards in hand and is about to take effect damage he removes I.D.G. from the graveyard to negate it. And Lotten chooses an monster or magic/trap. (while negating the damage) Kiryu draws. If it's a monster, Lotten takes all the damage Kiryu has taken that turn, in addition to the negated damage. If it's a Magic or Trap, Kiryu takes all that damage. If Lotten refuses to choose a type, he cannot inflict damage that turn.
He later then pulled a string of Infernity release special summons to end up with straight 5 monsters on his side.[/spoiler]
