"Eren, maybe you haven't realized that you are in trouble here."
Ron said in a threatening tone.
'Have you?'
Thought Eren to himself as he maintained his outwardly stoic expressions.
"What are you planning to do? It's not like I can't defend myself against two of you. My lightning element alone gives me all the advantage I need to bust your balls."
Said Eren while folding his hands. He knew the duo must have taken some countermeasures this time against his lightning element spells for it to be this confident in itself.
"That might have been true. But don't you think we might have known that and we did something about it?"
"Yeah? Like what?"
Said Eren with an uncaring attitude.
"Like this!"
Said Ron and showed Eren what he was wearing under his shirt by pulling the collar to the side.
Eren understood where the berserkers' confidence came from. They were wearing lightning spell proof armour under their clothes. F-Rank disposable artefacts, Eren guessed to himself.
