'Soul Vision?' Number One repeated in his mind as he observed Luna's eyes. He has seen it a few times in the past but never really knew what it was. 

'It's a Soul Art that allows you to sharpen your sight. You can't see Luna's Shadow Steps right now but it wouldn't be the problem with Soul Vision. You can use it to see her attack sooner and dodge or counter in time,' Nami explained and smiled at the good news, 'I actually already decided to master Soul Vision Art for the third feather. We just need to cultivate more to make it.' 

Number one's eyes brightened and he showed his approval by rubbing her waist. He still remembered the time when he faced Luna and he couldn't even see when she attacked with her Soul Sword.

"Is that so surprising?" Luna questioned Liss' reaction. "That's the most basic Soul Art one can learn. To think a member of the Disciplinary Guard doesn't know one. That must be embarrassing."
