I’m not going to lie, that’s a pretty hard thing to answer considering I love pretty much all of the characters for certain reasons or another. But I think if I had to answer…
–I’d pick Naruko Io, definitely.
I think it might just be because I have a thing for his character type–reserved, loyal, protective, intelligent, and yet with a very definite layer of passion and care underneath the infinitely more reserved “outer layer” of his personality, so to speak. There’s also the fact that while he’s hardly the most giving or flawless person out there, nor the most relatable, he’s got a certain–charisma to him that I’m drawn toward, I guess? I don’t know if that makes sense. ^^;
Plus despite the obvious differences that would point him as a foil to Minako from Sailor Moon, he’s actually very similar to her (especially her PGSM incarnation), and I love comparing the Battle Lovers to their Senshi counterparts, so there’s that.
