Kiryu can still hear it clearly, the words spoken by his mother during the official divorce. When he was fourteen, '. . Don't hate him Kiryu. Your father did nothing wrong. No matter what happens he will always be your father. But.. ..I can't stay with him anymore. . . without it being too painful. '
For awhile the old man still stuck around, for at least 6 months. But eventually he left to go abroad and nobody has seen him since. A year later his mother re-married to Austin Hisame - the man who is currently registered as his legal father. Any connection to him and his original father only exists in blood, and no longer in records.
That's what Kiryu thought this entire time. But, it turns out Hisame-san is his real father.
