He cares deeply for the two as he is willing to stall Sulfur Pot to let them escape if needed. He originally lived in Tokyo were he was friends with Black Lotus. However, he moved to Okinawa after his parents divorced. After moving to Okinawa, he became a parent to Ruka Asato who later becomes a parent to Itosu Mana.
