Rikka boasts that she was raised at sea, ascending the ranks of her crew to become a great Ultimate Pirate. In reality, she's the Ultimate Navigator, but she'd threaten anybody that pointed this fact out with walking the plank. She's obsessed with the pirate aesthetic and lifestyle, even replicating their typical way of speech. She's loud, proud and unpredictable - with Rikka, it's impossible to predict what she'll do next.

Her voice should be in the mid to low range, slipping in and out of a stereotypical fake pirate accent. She is extremely expressive - typically overjoyed or furious, and when she feels hurt or scared the pirate schtick seems to collapse entirely.

By popular demand, the canon voice that she is most similar to is Akane Owari.
