Assass Classclass 174
Ignoring the one page that has the morphing of his emotions, this actually worked really well. He was still extremely pissed off as noted by his tentacles not changing colors and pretty much focused the entire brunt of his anger (which as Shiro mentions is when the cells are their strongest) into an attack that he has now foreshadowed twice as what got him out of his most dangerous situations. I found Shiro's death super satisfying because fuck that dude, you don't get to die like a main villain, you die in despair like the asshole you are.
As far as the emotion thing, it is a bit...much. It was a bit weird and I know what it was going for but I don't think it was executed very well. We've seen that the tentacles are extremely responsive to a variety of emotions so it makes sense but it just came off as cheesy when the manga never really strayed into that territory before. You could simply have had him concentrate all the anger in his tentacle cells to the tips of his tentacles without any of the emotional range and it would've pretty much been the same thing. You also would've been able to have him say something during it to get the desired effect to show that he had control over his emotions and was instead using his good ones to control his bad ones.
Still, was a decent enough chapter. Kayano's fate is still up in the air, but not looking good for her
