Ryu was surprised when Angelo charged him, and thus was able to react as well to his attack. While he did instinctively solidify his ribs, it was two slow and one of the needles got thorough. Luckily, Angelo wasn't able to aim to well with his Senbon shooter, so it didn't hit any major nerve centers, and over all was just an annoyance. Ryu pulled the needles out, letting his jinchurikii healing rate take care of the small wounds. Looking at his opponent, he thought of the best way to proceed. If charging head on didn't work, then lets try charging from below. He quickly went through the needed seals, using only one hand so that he could still wield his blade while doing such, before he he again spoke the name of his jutsu.

"Earth Style: Hiding like a Mole Jutsu." 

As soon as he spoke the words, he slipped into the Earth like it was water, leaving behind a hole in the ground where he had been. Once underground, Ryu then began to dig all around the area they were fighting in in a random pattern, so as to weaken it. This meant that even if Angelo dodged his next attack, he would become trapped once he made contact with the ground. Next, he charged at Angelo from directly below him, holding out his blade in front of him and charging it up with Fire Chakra, making it take a blackened and charred appearance. The moment it broke the surface, he released and quickly retreated as he made the release seal, calling out the name of his Jutsu.

"Fire Style: Skeletal Eruption Jutsu!" Upon his speaking of the phrase, the blade would suddenly and rapidly expand upward and outward, forming a spire of charred bone before violently exploding, casting a large amount of shrapnel outwards, and a sizable column of fire upward into the air. Ryu would still be underground, however, readying to attack the Straw-hat wearing Kumo-nin the second he had the chances with a kunai. He would have used another bone blade, but he wasn't able to form them near instantly yet with out harming himself, so he didn't have the time to do such while in battle.
