The Tengan (天国の眼; lit. Heaven's Eye) is Kekkei Genkai appearing in the Land of Blizzards only recently. The Tengan is a diluted and mutated offshoot of the Shingan, through several generations. The Tengan has only two known possessors, Ayase and Mikiko Mizusaka. Whether the Tengan is a passable Kekkei Genkai or a unique ability restricted to them alone is unknown.
