Yoko Tsuno has Daughter of the Winds, with Old Retainer Aoki's Heroic Sacrifice, Seiji Tsuno being unable to tell his daughter that the old man who took care of her as a little girl pretty much killed himself for her sake and asking Vic to do it instead, and Yoko being this close to an Heroic BSOD... The worse part went more of less like this:
Yoko: I... I was so selfish! So arrogant! And Buddha punished me by taking Aoki-san away!
Vic : No, Yoko! It wasn't you! It was Aoki himself who decided to do so! Don't blame yourself...
Yoko: I'm sorry! So, so sorry!
