I've been watching Tanaka-kun is Always Listless, and I couldn't help but notice that Ohta really, really looks like a male version of Kiki from Snow White with the Red Hair!
Their basic look is similar, though Kiki's eyes and his really differ.
They both take care of those around them.
They're both kind of tall & beautiful.
They both know how to attack / get into it!
And they both know how to give an inquisitive look!
