Since Gaeru knew he was grabbing onto Masamune tight with his tongue, he power jumped vertically, avoiding a couple of arrow shots with much ease. He then swiped his weapon around the battlements of the castle's high walls by using the tongue as an extension of his weapon's reach.
Still, it was a long shot considering he could not see too clearly anything too far away in the darkness. Gaeru was estimating his attack on the torches that were lit up as a guide, but in no way the frog swordsman could know whether he was able to injure or kill the archer guards.
Yet, his broken sword now imbued with the Senior Guard's blood unleashed a terrifying energy wave that shook the battlements. The bloodied energy wave had the same damaging effect as the bloody phantom which Gaeru had previously triggered, causing his attack to corrode some of the high walls along with the destruction done by the initial wave of energy.
