Crimson Backlash Wave

"What you saw was the Crimson Backlash Wave."

- Yawaragi

Crimson Backlash Wave is an additional technique of the Kurikaramaru sword that Moroha finally is able to tap into and use in Double-Edged Moroha against her former mentor's Scattering Winds ability. It is not utilized as frequently as its original attack, only in extreme situations unlike the Backlash Wave of her hanyō father's and daiyōkai grandfather's.
