Ranpo.. truly is the MVP no doubt. This is why he's my favorite character.
"The one who transcends even ability users, the strongest man in the agency"
I love how Ranpo exists, not because he's just a character that shows how equal he is to even ability users, but someone who goes beyond and transcends them despite not having an ability whatsoever. He's like an anchor to show ability users that they're not omnipotent and those without abilities can be just as amazing.
His character seriously is better when you see that he's very childish and pampered and though it's a trait that everyone finds annoying and a trope that usually shows how they need to change for the better, Ranpo truly deserves to be spoiled and childish, I mean look at how smart he is.
I especially love how it's Dazai, one of the most cunning characters in the whole franchise who acknowledges how scary and amazing he is. While Dazai is cunning and smart, I think Ranpo is the one person who's smarter than Dazai and Fyodor and that really says something when people call them monsters they can never comprehend.
