Absolutely. As her teacher, I fully believe Akko is capable of reviving the Seven Lost Words of Arcturus and opening the seal to the Grand Triskellion. She will need to take her studies more seriously, certainly, but I've seen time and time again that when she puts her mind to something, there is almost nothing she cannot do.

She freed a spirit that was trapped for hundreds of years in her own grief. ... I know she can do it. I believe in her. That's her magic, after all. Her belief.

[ She smiles brightly. ]

And whatever I need to do to help her with it, I will. I can't do it for her, but I can teach her what she needs to know. I know the Words very well.

[ ... But isn't that a funny thing to say? Wouldn't those Words be only well-known by someone looking into such an obscure subject? Odd, that. ]
