Blue Archive: Founding the Federal Strategic R&D Department

Main heroine: Hanagang Yuzu (a Yuzu fan who finds mechs convenient to use). Half-heroine: Shiono Noah (makes it easy to hand things over in the side stories).

It mixes in elements from Girls' Frontline and Ultraman. There are lots of stories about the engineering department, but they won't overshadow Sensei's main plot, which will get about half the focus.

This is the story of Sakurai Chiku, a young high school student who loves playing CS and Girls' Frontline. Even as an adult, he still enjoys watching Fish-Head Hot Mama, while dreaming of developing his own armor or turning himself into an Ultraman. He's a good-looking student, rated above 80, and was an ordinary kid with decent grades. His roommate played Blue Archive every day, “convincing” him to check it out too. One time, while trying to develop armor, he accidentally killed himself. So he ended up in Blue Archive, where he gained incredibly advanced technological expertise. He joined the Federation to secure resources and, as he wished, developed the Nexus Armor, the intelligent war AI Hyper, his custom-built Flame Thunder armor, Shield Mountain, various auxiliary armors for the military, and other war mechs. He also met several talented students who weren't part of the original story, and together they helped Sensei change Kivotos. But a special kind of will appeared in Kivotos. Some students can awaken “Possibilities,” extraordinary abilities born from an extreme will. These include surviving without a Halo and turning Halo fragments into tools to enhance themselves, or controlling other students' emotions. They're few in number, but they're still a threat. Fortunately, most of them aren't allied with Gematria, the Decagrammaton cult.

The story will definitely differ from the original to some extent. It won't follow the original plot exactly, though the butterfly effect will be small and the story will still broadly follow the original direction. The side stories involve the Ultraman world and will be written after the main story.
