Well... I created an account for the sole fact I want to provide my opinion.
First of all, Caska chose Guts because she knew Griffith wanted total power, not because Guts was better in any way. With that said, I think Guts never has trusted anyone as fast as he did with the witch. He might be at least ten years older than her, but since she is so useful when using the armor, it does not surprise me that eventually they will become even more in sync. Guts and Schierke are following the same path as their ancestors, and they had been acquainted for at least a thousand years. Anyway, who said that love literally means the ability to touch someone? I would love to be connected spiritually to someone rather than trying to see through their bullshit. She is the one this story had been waiting for. She is useful as hell. Those two certainly are learning a lot from each other, and both can mind talk between each other. As an added note, Charlotte was 16 when she got effed by the hawk (-The set of laws you have in your homeland do not apply to a fantasy story- Nobody cries with experiments with humans in stories, right? [e.g. Akira]), so it might happen in the future (If the story goes as it should). The witch might be around thirteen-fourteen right now, and Isidro might be around fourteen-sixteen (He was offered a freebie, if you remember.) The story might progress in lapses of years, pretty much as it has, coupled with its freezing effect to relationship developments. I do not know what Miura will pull off, but I am sure that spirit bonding cannot be surpassed. No other two characters have performed something that goes beyond humanity but those two. Sex is far from something like that.Lastly, I seriously hope not to see Caska as a main character anymore. House is already full.
Such wow.
