TDoHI Gang

The Disappearance of Hikaru Ishikawa Gang (or TDoHI Gang for short) is a catch-all term for the ragtag group of Hikaru Ishikawa's friends and mother.

History
The group was created and founded by Ayaka Ishikawa and Mari Hatori while they were searching for Ayaka's missing son. However, when Hikaru eventually returned home safely, Kiyoko Tateyama and Yuuki Kobayashi joined since they were close friends to Hikaru and Mari.

Members
The members of the TDoHI Gang are not in any particular order, hence why Kiyoko is Number 3 despite Ayaka "joining" before her. The group just thought that it would be cool if they had numbers, like they were in their own secret gang. These members include:

01. Mari Hatori (Pink)

02. Hikaru Ishikawa (Light blue/mint green)

03. Kiyoko Tateyama (Yellow)

04. Ayaka Ishikawa (Dark blue)

05. Yuuki Kobayashi (Orange)
