Betsuyaku's klutziness, which his other teammates tolerate or find amusing, tends to irritate Kon, causing her to sometimes scold or even physically punish him. For these reasons, he finds her slightly intimidating. Nonetheless, the two may hang out with their teammates even outside of Border. She calls him by his first name with no honorific, presumably signifying closeness, whereas he addresses her very respectfully, appending the honorific -senpai to her surname.
