Shinsekai Yori - 1x06 - 逃避行- Followmy.tv

Saki and Satoru get themselves trapped and with no chance to escape, until Saki remembers Satoru's mantra and uses it to have him recover his powers. Instead of fleeing with her, Satoru decides to fight the Ground Spiders, aided by Squera and the surviving warriors of the Robber Fly. As the group survives several ambushes made by the enemy, Satoru shows signs of fatigue for overusing his abilities, but despite Saki's protests, he moves on until they have an encounter with a massive army.
