Chiri is the (acting) Class Representative for Class 2-へ ("2-He" or "2-6"/"2-F"), whose name in hiragana, when compressed, can read "きっちり" - "kitchiri" ("exact") - referring to her obsession with equality and conformity. Her first name also lends itself to the words "埋める" - "umeru" ("bury") - and "千里眼" - "senrigan" ("clairvoyance") - alluding to her favorite weapon, a spade, and her third eye, respectively.
