|Japanese name:||栗木 ロナウド|
|Nickname:||Clicky, Ronny, Kurikki|
Height: 186 cm
Ronaldo is a firm believer of justice. He rarely ever budges on matters of protecting the weak, being very stubborn to the point of being arguably pig headed in situations that require his leadership. He is also quite hot-headed, preferring to let action speak rather than words.
Ronaldo believes everyone should be treated equally, and no one deserves to suffer due to lack of basic necessities, no matter their skills or contribution to society. His goal is to use Polaris to force all humans to contribute to society and treat everyone equally. Even though he acknowledges the effectiveness of Yamato's Darwinism views, especially in dealing with the current crisis, he can't ignore those suffering in front of him and he refuses to accept such views as a societal norm.
