Bab 82: Chapter 81 : God of Dead

Standing opposite of Thanatos, Satoru decided to literally forget all of his humanity, having his mind entirely fixed by now by the speed of the potion Cassandra concocted.

Grinning and cracking his neck, the now black haired boy took a step forward, immediately having lightning cackle around him as he activated [Storm Cloak] as he formed [Shock Rods] in his hands and threw them at his opponent. 

Sidestepping all of them except the last one, he caught it the last one.

"Mere child's play. And here I believed I'd take the soul of the Godslayer to the depths of unbearable suffering. Disappointing."

Thanatos began to take heavy, slow steps towards Satoru as his grin grew larger. [Thunderbolt] was launched right onto him yet he didn't even flinch. He was struck yes, even having the boy doubt if he'd miss but he tanked it.

Is this God of Death invulnerable or truly immortal?
