Rebellion of the Missing Ring

Rebellion of the Missing Ring (亡環のリベリオン) is a spin-off manga of the Steins;Gate visual novel focusing on Suzuha's experiences of the 0.000000, 0.337187, and 0.409431% worldlines. It introduces new antagonists such as Kayano and reveals new information about the resistance group Valkyrie and SERN on the Alpha Attractor Field.

Overview
The Valkyrie resistance burst into the room where Rintaro Okabe is being held prisoner by Nae Tennouji. Nae escapes and Valkyrie cannot get to her.

They manage to get Okabe out, and Itaru Hashida rushes to Okabe. The Valkyrie tell Hashida that by the time that they found Okabe he was already dead. Hashida starts to cry, and scream, telling Okabe (even though he was dead) that 'There's no way I can make a time machine alone!, There's no way I can change the future like this!'.

Then Itaru Hashida notices his lab member badge, and his screams stop, but his tears stay. He gazes at it, thinking that if something happened to Suzuha or Yuki (his wife), he could never forgive himself. He then passes on his lab member badge to a young Suzuha.

He then takes a lab coat, and mimics Rintaro Okabe's mad scientist impression, trying to make himself get enough courage to change the world.
