"Onee...-san?!"

After Mayumi has fought the creepy Zetsus, she met her older sister, who died in a mission when Mayumi herself was only 17. She can't believe that Nagori, her Onee-san, is alive again but Mayumi has to realize that she has to fight against her own sister. Before her sister died, the sister where known as "Sandā no shimai", what means "the Sisters of Thunder" because they were fantastic at using Raiton (Lightning). Yes, i failed with the lightning -.- I tried so much times, but it didn't want to work >.< I love her eyes *3*
