Mine would be a short sword with a crimson red hilt and white ribbons that flow due to the fact that its spirit energy continues to grow. the phrase i would say to release it would be, strike the flowing skies, Tenro. that would cause the sword itself to disappear. Then the wind would shift and i could control all air and wind along with the air pressure. after saying bankai i would gain new clothes. closed chest test with normal samurai shoes. Also my sword would reappear but the blade would be made of wind and could but through almost anything.
