Yuna: "So we'll have to forget the fact that Regis put his life at risk for us? Even the fact that ajussi put his life on the line to protect us? ... Headmaster, is it really alright to forget all of that? All of you put in so much effort for our sake... Is it really okay for us to live without knowing that?"
Rai: "Of course. Because they're not hoping for their actions to be remembered by anyone. They have merely done what they wished to do."
The interaction between M-21 and Rai in Chapter 256 is heartwarming at its finest.
The previous lord's latest post-mortem message has its funny moments, but it's also heartwarning to see how much he (and Raskreia) cares about Rai's well-being, how much he is happy to see old and new faces, and finally, how much he is proud of his daughter Raskreia.
