"And so, ......I have decided. ............I cannot bear to spend my dimmed, remaining years procrastinating like this. If I have one final coin to bet, then I choose to abandon it to the whims of the Demons' Roulette. ......The power of magic is always determined by the risk of the gamble. Like visiting a shrine at the Hour of the Ox in ancient Japanese sorcery, to nail a curse doll to a tree. Magical power is produced specifically because of the risk that it will be seen within the seven days the curse takes. The greater the risk, the stronger the magic power will be."
