I've finally finished Silverio Vendetta and anons didn't lie. Kamige. I want to go over everything I like, so

starting with the OST, it is simply great, I especially like the SOL BGM with singing. But Vendetta's https://www.youtube.com/watch?v=Iv6ZoSdyg2w and Christopher's https://www.youtube.com/watch?v=hXWtXeFbG_k themes steal the spotlight, no contest.

As for character design, Vendetta stands above all for me, her design is the reason why I started reading it in the first place. Silver hair. Pink eyes. Pale white skin. Flat chest. Tiny body. Gothic lolita outfit to highlight all these features. Chris, Zephyr, Chitose, all look good too and there is not a single thing I would change about their appearance. (is Zephyr wearing the same scarf as his sister?)

Vendetta's voice was nothing like I expected, only having seen screenshots of her smug face and knowing (almost) nothing about her, I expected her to sound like Chitose, but younger, gentler and softer. That said it has really grown on me and I wouldnt want her voice to sound any other way. Every character's voice fits them and that said Chris is my favorite.

Nothing will top cursed mecha demons fighting amidst post ww2 Yamato for me, but the world is cool too, not the most in-depth, but enough. Esperanto, Planetes, Amaterasu, it's all explained and no questions arise.
