Seiya - Double Crimson Boom

The Berserk Hero already has both hands on the two swords at his waist as he charges Oxerio. The blades simultaneously slide out of their sheaths in a double arc, creating an X-shaped slash.

“Double Crimson Boom...!”

The move that defeated Grandleon returns—even more powerful than before—as  Seiya  wields  two  swords.  The  moment  the  crimson  cross  is  carved  into Oxerio’s body, he is effortlessly sent flying back until he explodes a few dozen meters  away  with  a  terrible  screech,  but  the  blast  never  reaches  us.  I  don’t know if Seiya immediately reverted into an Earth Spellblade after using Crimson Boom or if he made preparations ahead of time, but a tall stone wall suddenly emerges from the ground and protects us. After a few moments go by, Seiya lowers the wall.

“I put up a stone wall just in case, but the explosion ended up being a bitlackluster.”
