Kuran Hoshiumi. Originally an active Grim Reaper, he was so captivated by the taste of "Kamatama Udon" he ate while on the job that he resigned and opened his own shop. He generally has a "gentle and airheaded" personality. While he has a somewhat unworldly vibe, he occasionally shows a sharp, unfathomable scariness. Grim Reaper Udon Cafe No. 1 only sells Kamatama Udon and Cafe Au Lait made by Kuran. (Please look up more details via AI.)

She closed off her heart following an accident and exists in a state of "living while dead." She makes no friends, seeks no pleasure, and hides in her shell playing the "good girl." She stops by the Grim Reaper Udon Cafe No. 1 on a whim and begins spending time with the strangely human-like Reapers and a former classmate (Akira) who has returned as a half-dead boy. Through these interactions, she gradually regains her emotions and true feelings. Though she is often flustered, she is very kind at heart and reliable. (Please look up more details via AI.)
