Wow...that went down fast but to be expected of Inagaki.
Right off the bat, this is setting up the victory. Oh wait...Medusa is out of juice. Hopefully that shrapnel that hits is torso is enough for Stan to think Senku will bleed out and or Stan is forced to retreat with Kohaku likely to go after him.
Luna likely will be kept for information, but hopefully Stan does not have other guns with him. As long as this isn't the case, the remaining fighters will be able to force him to retreat.
I'm not sure about the accuracy of what Xeno did with his calculations, but it was a fun addition to the chapter. Xeno and Stan knowing each other (Stan giving Xeno a chance to think it over) was a great addition for me. The funniest part is that Xeno knows Senku's height from meeting him in person, so the calculation part almost wasn't necessary.
