Why is this quote important in a duel?
If you have the time to think how you gonna lose the duel in the coolest way, why don't you hold the never giving up spirit( a good spirit that we should held in a duel) and survive till the end, it might turn out to be a winning out come.
Always remember, never give up~ Not even when you draw no miracle.
