Mirai-san and Serval met Serval's friend Caracal, but Caracal seems to be very angry at Serval... What could have happened?
Because Serval-san and 
Caracal-san are nocturnal,
لأنّ سارفال-سان وعنّاق الأرض-سان
كائنان ليليّان
Ya que Serval y Caracal son nocturnas,
Como Serval y Caracal son nocturnas,
Siccome i serval e i caracal sono animali notturni,
Como Serval-san e Caracal-san são noturnas,
Сервал и Каракал ночные животные,
