During her original release, Kiriko's Hyper, Final Surgery had a game breaking glitch. If the player used the card to KO someone on the same panel as Kiriko, the game would crash, resulting in the board and all characters disappearing and sometimes screen distortion.[1]
Kiriko has voice lines for healing, despite not being able to do so in-game.
In Xmas Shooting - Scramble!!, Kiriko refers to herself as the intelligent elite of the Warudas.
Appropriately, her voice actor Sakura Miko describes herself as the elite shrine maiden of hololive.
Unlike most characters whose names are not titles (such as Store Manager), Kiriko's name is written using kanji rather than hiragana/katakana. Her name uses 斬 meaning "to kill/cut/slice someone with a knife" and 子 meaning "young woman".
Forced Revival and 
Final Surgery. She also appears in the artwork for 
Path Blockers.
