Hmm. I'll say Isamu is my favorite male protagonist in Macross too. I seem to have a thing for senpai or aces, because I love him, Roy, Michael, Max and Messer the best (Keith's ok, but nowhere there I like him more in the novel and manga, but I
do love his voice actor. I couldn't care about Brera).
Roy was my first cartoon crush and his death crushed me in another way.
