During his younger years at 15 years old, Clive has shown to be a kind, honorable, idealistic and caring individual, with a strong determination to prove himself and find his purpose after being passed over as Dominant of the Phoenix. Despite not being chosen by the Phoenix, resulting in his own mother scorning him, and Joshua becoming both the Dominant and heir to the Grand Duchy, Clive doesn't hold any ill-feelings, jealousy or even envy towards his younger brother.
