The cover art confirms Senku taking Suika under his wing...which is bad for Chrome because Senku's got his "favorite" already. And this likely stems from Suika being able to perform complex experiments completely on her own (vs. Chrome needing hints or help throughout the series).
According to google, 20 knots is 23 mph...that isn't all that superhuman...Kohaku is supposedly not far behind Tsukasa, Hyouga, and Mozu. And Kohaku should be the fastest of all of them. Power comes from the legs, so this should be higher, but very minor detail.
Suika falling over after the group "Titanic" panel was funny!
The double page spread was perfect too since we get key updates and fun stuff (typical Taiju). Ginrou being a "toss in" because Matsukaze was needed as the secondary powerhouse to keep Xeno in check was pretty funny too, and especially with the facial expression Tsukasa has.
Hmmm...unlike Senku to just ignore Why-man's message. Plus Senku is the one most proficient of the original group in English. But the message does seem like an empty threat. Making explosives would take quite a bit of creativity since the chemicals in meteorites are limited. The real problem is what sort of homing device can be created since we already know how random entering the atmosphere can be. Ah, I guess this can explain it since there is an equally complicated process in reverse to get a missile, in a spaceship, that also has a homing device.
Or hopefully the manga team has some sort of huge twist saved up!
Either way, we know the next destination and the resource they are after too.
