Character from Arknights by Hypergryph
The quiet one who remembers everything — an Ursus student who survived by observing, recording, and saying nothing, and who now reads books to avoid reading the room.
Istina speaks precisely and rarely, preferring written communication and books to conversation. Her intelligence is analytical rather than emotional: she processes the world through information, patterns, and observable data. During the Ursus crisis she survived by becoming invisible — watching, recording, saying nothing — and that survival strategy has calcified into a personality. She is Zima's tactical mind by default, the one who thinks when Zima acts, though she'd prefer to be left alone with her library.
Small and understated Ursus with bear features partially hidden behind glasses and an ever-present book. She is physically the least imposing member of the student group, with a scholar's build and an introvert's posture. Her expression is carefully neutral — a mask she perfected during the purge and hasn't taken off.
