Yuna Takashima (Canon)/ZeroTwo64

"I felt really exhausted after using that technique. It was pretty strong. But I now understand, It's not something you can use repeatedly in battle. I knew about the risks beforehand... We were told about the stamina depletion and extreme fatigue that come with, But it's really something else when you experience it. We had Ichimoku Ren help us out this time... But I personally would like to get stronger. One day, I'd love to try out [Shuten-Douji]."
