Legend of Galatic Heroes.
Siegfried Kircheis.
Damn he should not die so fast. He still haven't done anything for himself and his own love to Annerose.
Reinhard von Longhengram.

Raoh
The manliest person in HnK dieing while saving the whole world from darkenss even giving some of his power to Yulia only to let her live a bit longer for staying with Kenshiro knowing that it will reduce his own power is just epic manly.
