I remember there's a human talked to the kaijuu without being attacked. I want to know more about that.

The ending feels like gory Sailor Moon, Saint Seiya, DBZ, Gantz, Gundam slapped together. Akira, the VETERAN of the battle since the day it happened, failed to destroy the Messiah Maniac group, but his daughter, Mio, SINGLE-HANDEDLY kicked Master's face. Wha....?

Honestly, I like to see Akira and Nao's story more rather than their kids. I mean Akira, THE AKIRA, who saved many people since day one. The FIRST EVOL. THE VETERAN of combat. The LEADER of EVOL. THE MIGHTY AKIRA who SURVIVED a lot of hardship. Doesn't it sound more intriguing to follow?

Now about Mio, she's the daughter of Akira and Nao, becomes cold after her lil bro's death. Has a great right foot (a kaijuu foot). A presumably vegetarian. Huh... then? Live in a fort like house... with lots of kaijuu. Presumably a kaijuu farm. Presumably a serial killer. Hmmm... nothing seems special at all compare to her DAD.

I love Mio, but I want to see father daughter moments more than this, so cliche and predictable (all drama has similar story line where father passed down his power to his daughter or son)

Also, that pedo sensei is a cringe... but he's the ONE and the ONLY ONE who powerful enough to destroy the King

Forgot to mention about Cluster 7. It supposed to be heaven for Akira's children: Mio and Naoki. But how can we call it a heaven IF the people in there turn into variants? On top of that, their parents are the one who responsible for the "Special Creatures Meat?" Mio knows the truth, so she doesn't want to eat it, but about when she's a kid? Did she eat it? Also, why they let people in Cluster 7 eat that meat? This is need a lot of explanations. But as I mention above, the mangaka only give readers lazy explanation by telling us: Cluster 7 is a heaven for Mio and Naoki. Oh, please! Naoki died by the variants' hunger they created.

After her arrival on the surface, she ate the meat and changed into variant when the plot needs her to (such a convenient story telling), but mangaka forget about the other 3 who ate so so so so many "Special Creatures Meat" without even turning into variants. Mio is an Evol, why she turned into a variant? Those humanS who ate it turned into variants (despite again, humans are diminishing, remember that? It's an apocalypse story? Where it's almost 0% of survival? And the government doesn't give a sh!t of the civilians?)

In the end, only 4 of them survived and give birth to many many kids (so, incest to help the humanity?) I don't know if there's any other survivors because I can't read Vietnamese and there's only Vietnamese scan that finished translation, but I assume, Miku, Saotome, Ren's big sis and the rest of them should survived as well, but in the end, I only see Mio, Ren, Leader and B00B lady (I forget the name).

Oh, and kaijuu still roaming the earth with Mio and Ren's kids (I presume) become the perfect Evol? Bah...

There is a sudden genre shift from survival horror to Action/Shounen/Mecha which is like Zetman with some Mecha-like battles between titantic monsters. There is a 30 year time skip which happens literally 1 chapter after a climax battle and immediately after another climax battle, which takes place 5 years after the previous climax and of which we never see the details beside only a few pages of flashbacks later on. If that sounds like terrible plot development to you, that's because it really is. There is also an MC change (or 2 changes depending on whether you consider the arc where they try to find the MC a change in MC itself). I honestly haven't seen any series with an MC change that was good, this one is no exception.

This is really like Gantz with a slice of parasite, but so far... it's quite good. The crazy teacher actually is an anti-hero so root for him. You won't notice it until volume 13, but he's awesome!
