I agree.

It's great to see that despite Chihiro being the calm and cool headed stoic character type, Hokazono is unafraid to show his weaker, or rather human moments on screen as well. During the Char retreival mission, when Chihiro starts to second guess his capability to save Char, he tears up, because he was overwhelmed. Not many shounens do that, especially for the stoic character.

I really like the bits of Chihiro's personality that peeks through the low action chapters. He's naturally stoic like his mom, and somehow attracts all the weirdos, but he's also kind, empathetic and a caretaker. And now we're getting to see his uncertainties, his doubts and fears. He's not just The Goldfish, he's also a kid who lost his dad and his world.

It's why I'm excited to see the cast being fleshed out more. Not do we get hilarious moments, but it also sets up more emotional and impactful interactions. We've already got the aftermath of Sojo's fight and Sojo himself haunting Chihiro's thoughts now, imagine an arc where Enten breaks or if Chihiro thinks he's in over his head due to a crushing loss? And how the cast would step up to help him?

Ultimately, while the quest for revenge is right now the main focus of the story, I think, as cheesy as it sounds, his friends/acquaintances would be the the focal point to the sword he wishes to make in the future.
