The End of the Battle | Twelve Demons Eliminated

The demon's eyes widened in utter dismay as Seiya cleaved through two of the children with clean precision, without a single moment's hesitation. They collapsed to the ground, their sundered bodies mere inches apart, pooling blood that trailed down the shrine stairs.

As soon as Seiya struck down the boys, his sword's tip sank, its weight bearing down heavily. Seiya leapt back, landing on his spot, knowing the demon would retaliate. He re-adjusted his grip around the sword that was getting heavier each passing second—fully aware that Kaeliyus' fatigue was the reason behind it.

Rather than retaliating immediately like Seiya had thought, the demon, however, was struck numb. 

Seeing as Seiya hadn't killed any single villager till that point, he had thought Seiya wouldn't kill any human and was only there for them, the demons. So, Seiya's brutality left him numb for a moment.
