Appearing in his usual garb and wielding his sword, Thanatos has been concentrating on supporting those who are better able to handle the bigger dangers. He's not used to fighting without his normal abilities. (And he's still a little out of it that he can so easily lose what makes him Death Incarnate.)

Still, that mongoose heading towards Mami is deftly sliced in two.

"I can." If Thanatos is going to fight, he'll do so as painless and instant as possible, as gentle of a death he can give. Besides, him and Mami have worked together similarly like this before. He'll draw their attention for others to pick off.
