Kagening
Kagen is so rare, it’s like finding a golden goose. If you meet another Kagen, you two will try to kill each other like it’s a competition.
Kagen: 'You’re a Kagen? Let’s settle this with a duel.'
Kagen: 'I’ve killed three Kagens before breakfast.'
Kagen: 'I don’t know you, but I hate you.'
