Rui was highly curious about what communication with intelligent creatures of other species was like.
But he was conflicted. It wasn't a combat-oriented technique, which meant it wouldn't make him stronger in combat or even increase his ability to complete missions. The only thing it would do was allow him to communicate with animals.
Yet, despite this, he really felt the urge to master the technique.
"Hmmm..." He had a complicated expression on his face.
After a bit, he finally decided to go on with it.
"Screw it. It's my Martial Art, I get to do with it what I want." He rationalized, trying to make himself feel better about his decision. "I bet there are some missions centered around the ability with the ability to communicate with the more intelligent life forms."
He grabbed the scroll for the technique before plopping it into his pouch.
With this, he had selected all six techniques for his next training stage;
Mindmirror Symbiote.
Mind Mask.
Shadow Step.
