Hidden City's former Investigations

Investigations (Main Quests) *Changes at Jun-Jul 2025

The opening story and several investigation cases in the Diary were changed for all players. (For players who joined after January 2025, these changes were already applied.)
･Introduction (the City) → Case №1 [Welcome to the City], №2 [The Fog of Distortion]
･№1 [Beauty and the Beasts] → deleted
･№2 [Secret Organization] → №3 [Mysteries of the Order]
･№3 [Unexpected Guests] → №4
･№4 [Ghost Train]→ №6
･№5 [Enchanted Ball] → №7
･№6 [Isabelle's Secret] → №8
･№7 [Keys to the Past] → №5
･№8 [Alex's Angels] → №9
･№9 [Foggy Plan] → №10
　　　　　：(every № +1)
･№102 [Chasing Dreams] → №103
In the Diary, the City's Introduction parts #1–6 were deleted from "the City." As a result, the tab numbers for the characters' rooms from #7 onwards shifted. Now, the Detective's room appears to the left of tab #1.

日誌内のオープニング･ストーリーといくつかの捜査ストーリーが全プレイヤーで改変された。(2025年1月以降の新人プレイヤーに対しては既に変更済み)
･始まりの書(シティ)→ Case №1 [ようこそシティへ], №2 [歪みの霧]
･№1 [美女と野獣たち(改訂版)] → 削除
･№2 [謎の組織] → №3 [五賢守護団の謎]
･№3 [予期せぬ来訪者たち] → №4
･№4 [ゴースト･トレイン]→ №6
･№5 [魅惑の舞踏会] → №7
･№6 [イザベルの秘密] → №8
･№7 [過去へのカギ] → №5
･№8 [アレックスの天使たち] → №9
･№9 [霧煙(けぶ)る思惑] → №10
　　　　　：(every № +1)
･№102 [夢追い人 ] → №103
日誌のシティの「始まりの書」部分だったタブ１～６が削除され、それに伴い７番以降にあった登場人物の部屋のタブ番号も前にズレた。現在タブ番号１の左側が刑事の部屋。
