"Fear is the mind killer", is wisdom from the old world Tsukasa once told me. A fearful mind is obstructing one's combat skills, rendering them useless in battle.
One needs to have trust in their skills, and do their best in combat, no matter the potential outcomes.
And if you die, you die sacrificing yourself for what you want to protect. There is no better way to go.
The fact that my brother and Mastukaze can react to thing so... Maturely?? Calmly?? Is insane to me. Because how the hell are you staring down at that DEATH MACHINE AS IF IT WON'T KILL YOU?? It's so cool how they do that... I wish I could do that...
