Daikoku Nikadou is a standout comedic figure in the series — the 29-year-old brother of Natsumi who has spent years conducting research abroad in America. His overwhelming fixation on his younger sister drives him to fiercely oppose her budding relationship with the elementary schooler Kanade Takahashi. Known for appearing in a traditional Noh mask and secretly hoarding objects left behind by Natsumi, his bizarre antics consistently spark uproarious, over-the-top conflicts throughout the story.
