Ah, what a bittersweet moment. On one hand, I like that he was able to keep the image of Aidra in his mind of her younger and healthier self without having to watch her waste away ill, but on the other... Either way, I loved badass Grandpa!
Just discovered the manga, what a gem.
I'm sad that the princess already passed away and quite impressed that with only a few chapter I'm completely attached to the characters.
