Okayu's playthrough was full of great moments. There was a really good one with your last encounter with Flint, where he talks about Lucas being happy that Flint finally found his brother. She has a great bit about wondering if Lucas ever felt like his dad cared about Claus more than him, always being off searching instead of spending time with him. It's great. Too bad I don't have a translation for that, but this part was good too:
Okayu: "Ah, the bouquet's changed again! Is he really coming here to change them day after day?"
Nippolyte: "Lucas, did you see Flint? That's too bad, he was just here visiting Hinawa's grave. He's gone back to search for Claus in the mountains again."
Nippolyte: " Search for Claus, search for Claus, visit Hinawa's grave. Search for Claus, search for Claus, visit Hinawa's grave. That's all your Dad is these days, huh?"
Okayu: "Yeah, but I'm sure that Dad is... When he's doing that is when he's most... How do I put it? When he's able to keep his feelings under control the most. Every time, every moment he's searching for him, thinking, "Maybe I'll find him today." That hope is what keeps him stable. And only when he's at her grave does he feel like Hinawa's there with him. Yeah... But, we're with you, Lucas!"
Nippolyte: "The saving grace is you, Lucas. You've become so strong and dependable. Somebody who won't cause Flint any worries. You've become such a good kid."
Okayu: "Yeah, he's right, you're really admirable, Lucas. All by yourself in such horrible circumstances, thinking, 'I need to become stronger.' Most people wouldn't be able to have those thoughts."
Okayu: "Man, it sure is heartbreaking for Flint. For three years straight, visiting Hinawa's grave and searching for Claus in the mountains; it's too much for me. Even though he probably already understands that it's... But he probably can't help but to keep doing it; how sad. Those thoughts are probably why Lucas is trying to become stronger. When I think of that, it's just somehow... Let's get going"
*Bumps into a tombstone*
Okayu: *sniffle* "Hold on, I'm not walking straight. It's so sad that I can't even walk straight."
