How the manga will adapt this chapter :
I don't know if Murata will follow this storyline, because since the "Garou arc," Blast has only appeared once more (because of Flashy and Sonic, if I'm not mistaken), and then the universe in the manga kind of "reset."
Despite the introduction of Blue (Blast's son), he hasn't received much attention (despite the green elf-style hoverboard).
It will probably repeat a bit of what happened in the "Garou arc"—Genos fights as hard as he can against Saitama, and unless Kuseno has the secret to finish Saitama off once and for all, either Genos "dies" in the fight (and Saitama throws Kuseno into the hands of the hero agency) or Genos is left in pieces, and as has already been suggested, Metal Knight and Child Emperor reform Genos at Saitama's request.
If One is enthusiastic, he'll probably wrap up this arc for good this month. Honestly, I just hope One ends the series, and without any problems explaining about Blue or if Blast will return. OPM has already given all it had to give.
(And after reading some nonsense Murata wrote, I wouldn't be surprised if One wants to end the story too.)
