While little of his private life outside Camp Buddy is known, it is shown that Kieran first joined Camp Buddy one year prior to when the game takes place, together with Taiga Akatora. Kieran is very friendly, as shown when he quickly befriends the other campers after he re-joined camp. He tends to overthink things, especially when it comes to his relationship with Taiga, and is very sentimental about it and past 3 months Taiga and Kieran break up without reason.
