Wagner Kanata's Links
Wagner is in denial with his other self, an image projected of himself but in feminine form. The feminine form does not mean it portrays his 'feminine' side but instead the gentle and caring side of his. Just like his mother. Kana's eyes are the same to his mother's. He is the weaker side.
Kana protects Wagner's emotional integrity, his defenses and self-esteem. As soon as those are broken down, she emerges to help him deal with them. Even as the 'other' personality, she fears for her fond of brutality to emerge against hers or Wagner's will. She is the stronger side.
Enishi is his close friend and blood-brother. Grew up together in Japan, they formed a very inseparable bond both emotionally and spiritually. At times of danger, he could sense the other's facing against danger.
