The double-headed demon has been stuck with magic powerful enough to fell a dragon. In the aftermath, Morlock feels sympathy for the demon dog and says he wants to try to save it. But then, Saitou and the others are struck by a surprise attack!
And if my own life is spent in the process, 
then I shall live on within you.
وإن أزهقت حياتي أثناء ذلك، فسأعيش داخلك
Und sollte es meiner gesamten Lebensenergie
bedürfen, werde ich in dir weiterleben.
Y si mi vida se agota en el proceso,
entonces, viviré dentro de ti.
Y si mi vida se agota en el proceso,
entonces, viviré dentro de ti.
Si la mienne vient à s’arrêter,
je continuerai d’exister en toi.
E se ciò dovesse costarmi la vita,
possa io continuare a vivere in te.
E se minha própria vida for gasta no 
processo, então viverei dentro de você.
А если в процессе истрачу свою жизнь,
мы будем жить вместе.
