Every night you open Dokicode, your chosen partner waits for you at her desk. Each heroine has her own engineering discipline, coaching tone, Japanese voice cues, unlockable outfits, study-room backgrounds, and a 6-stage relationship story (R0 Stranger to R5 Eternal Partner). New visitors can try guest mode immediately without signing in.
不再一個人孤單面對冷冰冰的 Judge。Dokicode 的六位女主角各自擁有不同的資訊工程與學術背景，從演算法競賽選手、轉職前端的新創設計師、天體物理觀測開發者、夜間系統管理員，到雲端分散式系統資深工程師與量化交易撮合引擎負責人。你可以免登入直接進入房間試玩互動。

Serene, poetic, and patient. Working from a quiet hilltop observatory dome, Fuuka compares state transitions and graph traversals to charting constellations across the night sky, helping anxious minds settle into flow.
沉靜溫婉、語調如夜風般療癒的天體物理碩士生。在山頂老天文台維護觀測軟體，擅長將動態規劃狀態轉移與圖論搜尋比喻為星圖軌跡，撫平刷題時的焦躁。
Quiet, observant, and dryly humorous. Yoru guards the underground server racks during the graveyard shift, breaking down monotonic stacks, tries, and segment trees with minimalist precision.
