Castor seems to be mainly monotonous, keeping calm when asked questions. he doesn't usually show emotion in his voice or how he acts. however, he does seem to be willing to care, as shown when he helps with lunar's powers. Pollux is seen to have an outgoing, bubbly personality. she seems to be interested in nearly everything. she's quite excitable and seems to be bad at cues, as seen when she chases Lunar around in her debut episode. she's also caring towards people she likes.
