Riyuki
Riyuki is a very calm and composed risihi, an amphibian species that floats! Riyuki is not very expressive, even by risihi standards (and excluding the traditional mask) but always seems to know just what to say. Still a lot of unknowns about Riyuki's species, but first because I have not mentioned any gender pronouns yet...I'm not sure if risihi are going to be all female (parthenogenesis), sex-changing (sequential hermaphrodite), or just plain hermaphrodites. Either way, not standard. Pronoun-wise, they don't care about gender, so there's only going to be one pronoun used by 99% of risihi individuals. They also cover 99% of their body in special clothing. This is to keep in moisture and protect their absorbent skin from whatever is in the air. Being very weak and frail physically, risihi are often skilled speakers.
