>>78299999I don't have many headcanons. Nidaime is like a cool, mature, sexy guy while Kaz is a calm, bright and friendly guy.
But I also like the love triangle dynamic with Jiyou, too. Basically they'd be 3 childhood friends. Nidaime and Jiyou are constantly fighting. Nidaime is the more popular and modern guy in contrast to Jiyou's more traditional loud martial spirit personality that's not as popular with girls. Kaz is always trying to calm the two when they fight. Nidaime and Jiyou are both actually vying for Kaz's affection.
