The Name

絆 (Kizuna)

Kizuna is the Japanese word for the bond that connects people to what matters most. For collectors, that bond lives in the stories, memories, and moments behind every card. Kin carries a double meaning: kin, as in family — and 金, the Japanese word for gold, the mark pressed into every cover.
