The center portion of Green's plan was to perform a large-scale ritual to unleash a powerful spell. That spell would serve as a preemptive strike to incapacitate Koutarou and the others. After that they would defeat them all one at a time. If they were all incapacitated Green's calculations told her that they should be able to defeat all of them with scientific magic.
“Green, what are the chances of success?”
Blue asked Green as she drew the magic circle. They were currently in a deserted house. It was wide enough for the spell, the roof was far up and the ground was sturdy. It was somewhat old and dirty, but it was more than stable enough for the ritual. Blue's voice reverberated somewhat as it was absorbed into the wide space.
“If it's a simple matter of victory and defeat than the chances of success is more than 80%.”
Green conveyed the future she had foreseen to Blue.
Her future forecast allowed her to see all possible outcomes, including scenarios where they never fight or there was no conclusion to the fight. Adding all of those futures up, their chances of victory in a fight was somewhere around 25%, but that number wasn't what Blue was after. Their chances of losing the fight was 5% and subtracting that from the total, there was roughly around an 80% chance of success.
“If it's 80% then we've pretty much won already. As long as we don't cut any corners that is.”
Crimson said as she stood up with her cane in hand. She had been helping out with the preparations of the magic circle, but she had a different job to do now.
“Alright, then I'm off. I'll leave this side to you”
“Are you fine going alone, Crimson?”
“Green, you help Blue. You're the only one that uses those weird machines that the underground people handed over”
“Alright, then leave this to us. Okay, Blue-san?”
“Yes.”
“Right, then I'll see you later.”
Crimson waved her hand and headed outside on her own. She had a job to do on the outside while the other two would create the magic circle. Being so active, Crimson much preferred to work outside over drawing a magic circle indoors. As she walked outside her steps naturally became lighter.
