Kouen (光焔,Kōen, lit. "Flaming Light") is a command based off the Fuurinkazan for Yaya to release a barrage of movements or attacks. In the anime, whenever Raishin uses Kouen on Yaya, with a shou formation, he releases crimson strings of magic energy onto her, while with a ketsu formation, he releases yellow strings of magic energy, enveloping her whole body, glowing off with the respective magic energy for a short duration of time.
