Reno flew quickly after the small goblin, hoping to find where this Horned King was and save Hen Wen. He had no idea about a Zodiac Sign, but compared to saving someone the Zodiac Sign possessed absolutely no significance to Reno. In fact, he forgot about the potential for one being here completely in his desire to save Hen Wen. Of course, Reno did not find the Horned King or Hen Wen when he got to just outside of the Horned King's chamber he found Belle shoving the goblin against the wall roughly. Reno smiled at her as he jumped off his Glider, the book disappearing and returning to being a glove on his hand with a small flash of light. 

"Ring, I didn't know you were here. When did you get here? Did you get here the same way I did? Cause I don't really remember how I got here... Also where are the others?" He asked these questions rather quickly in his usual fashion, but following his famously short attention span he quickly looked to Creeper, than to the large door in front of them. "Ah, but there's no time to answer that. The King guy is going to do something to When Pig according to Bard-san, so I need to hurry". He quickly moved past Belle, waving his hand at the door as a mighty blast of wind came forth, bashing the door open as Reno quickly entered the chamber of the Horned King, looking around and seeing the pig. 

"I've come to save you When Pig". He gave the pig a friendly wave and a grin before looking at the Horned King and the figure in the cloak. "Umm...I need to take When Pig back with me, cause he is my friend's friend. So please don't try to stop me Skeleton King".
