Schrödinger's Call: 'Soul Hotline' Event Lets You Call and Share Your Regrets with Mary and Hamlet, Voiced by Kana Ichinose and Rei Sakuma

Shueisha Games Inc. (Headquarters: Chiyoda-ku, Tokyo; hereinafter 'Shueisha Games') is pleased to announce the 'Soul Hotline' promotion for the novel adventure game 'Schrödinger's Call', an experience that lets you feel the pain and salvation of connecting with others as if turning the pages of a picture book. This event will run from today, June 3rd to June 10th. In this initiative, just like the wandering souls that appear in the game, you will be able to use an actual telephone to call the black rotary phone in the room where Mary and Hamlet are and have a conversation. What are your regrets? It is 21 nanoseconds before the end of the world. You are one of the souls with regrets. Mary is the world's last conversation partner who will listen to your regrets. So, pick up the phone. Surely Mary will listen to your regrets. In 'Schrödinger's Call', you connect with the regrets of souls wandering between life and death through the telephone. This event allows you to have Mary and Hamlet listen to your own regrets, just like the souls in the main game. Please call the toll-free number listed on the special website and try talking with Mary and Hamlet. The voices of Mary and Hamlet are provided by Kana Ichinose (as Mary) and Rei Sakuma (as Hamlet), continuing from the teaser trailer. If you include a specific keyword in your conversation, you might get a response from Mary...!? Have Mary and Hamlet listen to the 'regrets' you hold. ▼ Special 'Soul Hotline' Website: https://shueisha-games.com/games/schrodingers-call/tamashii-hotline/ ▼ Event Period: June 3, 2026 (Wed) to June 10, 2026 (Wed) *Please read the terms and conditions carefully before participating. *The phone number used for this event is a toll-free number, so no call charges apply.
