Yeah, Takajou is turning out to actually be a pretty good guy. Seemed like he'd be that shitty friend who'd throw everyone under the bus for himself but he's really going out on a limb for his bud.
Well, if you read other Okabe Uru's works, there usually a guy that looks shitty and rly annoying and also kinda useless at first, but later turn out to be a really great and nice guy. I bet Takajou is one of it
