The explosion in question had happened just outside the Blue Tower. The cause of it was the guided missile that Dark Green had gotten from Elexis. The warhead which had been designed to concentrate the explosion forwards easily punched through the magic barrier and the outer stone wall. Crimson could be seen from the hole in the wall.
“*cough* *cough* G-Green”
“Crimson! I'm glad you're okay!”
Crimson was having a coughing fit from the dust caused by the explosion, but didn't seem to be hurt. Seeing her like that, Green instinctively started tearing up. She was the only one who deeply regretted not being able to bring Crimson home during the last battle.
“Do- *cough* don't give me that, *cough* *cough* who would do that? Firing a missile *cough* into the room your ally is being held in. W-What would you do if I died?”
Crimson had begun tearing up as well. However, this was because the dust had gotten into her eyes and she had a hard time breathing, not because of her reunion with Green. Though it wasn't like she wasn't happy.
“It's fine, I made sure of it with my future forecast”
”By the way, what was the chance of success?”
“There was a 95% chance of success”
”Then there was a 5% chance that I would be hurt!?”
”No, there was a 15% chance that you would be hurt”
”... Then there was a 5% chance I would die...”
Green had used her future forecast to search for Crimson's position and then fired the missile from the distance furthest away. Of course, a forecast is a forecast, there was still a chance that Crimson would be in a different place. In the case that Green attempted this way of rescuing, there was an 80% chance of Crimson being unharmed, a 15% chance that she would be be injured. Combined it was a 95% chance of success. The remaining 5% were Crimson dying, which would of course be a failure. Green had fired the missile, well aware of the risk. It was only natural for Crimson to be fed up.
“Wasn't there a better way!?”
“There was... but this had the highest chance of success”
“... I'm interested, but you don't have to say anything”
”I don't want to remember them so thank you”
“It was that bad!?”
Green had thought up of several other ways of rescuing Crimson, and out of those plans, shooting the cell with a missile had the highest chance of success. Rather than Green being aware of the risk, this had the smallest risk involved.
“Wait, Crimson. The enemy is coming”
Green's future forecast which she had been maintaining for a while now told her that the enemy was coming. The most likely future was Yurika and Koutarou breaking through the door in 30 seconds.
“... You'll be telling me the details when we get back”
”Of course. But for that we'll have to escape first”
”And my cane?”
“I've brought a spare”
Green said and tossed the cane over to Crimson. Dark Yellow had made this cane a while back. During their preparations for the decisive battle with Rainbow Heart, Dark Yellow had been in charge of creating magical weapons, and this cane was one of those. Since this wasn't a personalized cane, it had a rough make and there was a limit to how much magical power could be infused into it, but it was much better than nothing. During the fierce fighting, it would be an easy but fatal mistake to lose your cane, so this was a useful and suitable preparation.
“Crimson, make yourself lighter and get on”
“Got it... Weight Saving”
Green was riding on top of a flying automated weapon and had flown up to the cell on the top floor. By escaping on a scientific weapon, the amount of magic they would use on their escape would be reduced, making it harder to follow their trail through magic.
