So, Melt and Kyouka are really in relationship, huh? At first I thought Cooldown behavior was suspicious; obstructing your side from killing enemy at the critical moment. But think again, X didn't command them to finish Rapid Rabbit. It looks like the trio were sneaking on X on their own. X just left everything to Orb Owl. So Cooldown blocking Melt from interfering wasn't wrong.
I'm a bit confused about Antinoid and Kaijin. Antinoid is their race, or may be just their organization, right? And Kaijin is the word to call strong monster, aside from the artificial ones, the generals' and X's battle form also called Kaijin, right?
This chapter sprang more question. What exactly is Antinoid? Where were they come from? What is their real objective? In chap 1 it's said that Antinoids came from other dimension to invade and destruct humanity half a year ago. But now we learned that the past battles were all X's plan to trigger Hayate into Kaijin. And look at their ability to disappear from human memory, with just this they can destroy mankind since long ago if they really want to🤔 THAT'S SO SUSPICIOUS! I can't make up a theory but I have a vibe that X was a human who's turned into Antinoid and want to turn everyone into Antinoid too. We've never heard of other Antinoid other than X and the generals. May be Antinoid is just an organization, not race, which consists of 5 of them. 🤔🤔🤔
Btw, I'm full X fan, lol. I'm cheering you, X! I know you are the real protagonist here >.< Go on!!
