Who knew the technique that he was going to teach was One Slash?

( The Sword Heart. )

Ifrit's golden sword body shook as four words entered Rin's ears.

"Sword Heat?"

Rin repeated Ifrit's words.

'Where did I hear these words before?'

She felt like she had heard these words before but couldn't put a thumb on when that was.

( The state, Unsword lets a warrior become one with his sword. The pinnacle of Unsword is only reached when a bond develops between the sword and its owner. They both cover each other's weaknesses while the sword also becomes a well from where the warrior can draw out energy. )

Ifrit explained to Rin. This was something that Rin already knew. But, she hadn't learned everything about Unsword. Thus, hearing the reality of the state, Unsword from Ifrit was allowing her to better understand her abilities.

( Once a person achieves mastery at the pinnacle of Unsword, a new wall appears before him. )

Ifrit's golden sword body turned and the blade was pointing towards Rin.
