Yes, I don't think the "It's just a drawing" defense could be played here because I'm not berating his existence in this story. Let him exist, I don't mind. He's part of the odd vibe of this manga. A vibe that I'm fond of.
I wouldn't go miles to ask the mangaka to remove him from the story because I don't want him to be. Again, he's part of the story.
However, no matter how you look at him, story-wise or in irl, he's horrible. His actions are unjustifiable if we're being reasonable here. Rape is rape. How can you justify rape?
The only reason you'd probably like him is preference, like you find him hot or something. Which I respect, you do you. It's dumb to reason out with preference. However, on a personal note, if your standards is Reo, I sincerely hope they keep that standard to fiction only. And I don't mean this appearance-wise.
(I apologize for the long reply OTL)

It's been so long since I wanted to uppercut somebody. I'm talking about Reo.
I loathe him with all my being. He's simply irredeemable. Even if he saves their lives from a meteor or something, he has done too much fucked up shit to even get a small fraction of the good light. He's terrible.
