I had zero expectations going in since I never read the manga, but this 1989 OVA genuinely caught me off guard. It was surprisingly progressive for something this old — like, the homoerotic tension was NOT subtle at all, and the fact that it's between siblings?? I had to take a step back for a second lmao. That said, I can't even be mad because the character art is absolutely stunning. Whoever drew these characters put their whole soul into it, they're gorgeous. It's a weird little OVA but it left an impression on me for sure.
