Oh my gosh, I knew it the moment I saw Aona's mother! That's why I'm kind of infuriated by Aona's father's actions and reasoning, but I feel like it wasn't meant to be malicious. Regardless, I'm so glad this arc was actually really sweet. Seeing Kuro grow and becomes more caring and defensive of Aona was really the cherry on top. we're finally seeing his character development. Overall, another great episode! And that ending really made me jump, are we finally going to see Dr Ramune's master?! Now I'm super curious!
