Compared to many gods, Athena is more like a child.
She has the playful side of a child and the ruthless side of a god.
She does whatever she wants, and never gives up on herself.
Probably for this reason, most gods like her.
In fact, she wanted to be the patron saint of Gemini from the beginning.
Just because she likes Castor better and his personality is almost the same as hers.
It's just that she is colder, more cold-blooded, and more ruthless than him.
