There are two main characters, Yuta Okkotsu and Toge Inumaki. Yuta is a swordsman who wields a katana. He can come across as slightly flustered or clumsy. Toge Inumaki is a Cursed Speech user who exclusively communicates using a 'riceball language,' where words are replaced with the names of riceball ingredients like 'Salmon,' 'Bonito flakes,' and 'Tuna Mayo.' He is quick to speak and can be assertive, often interrupting others.
