Princess Finis has some really formidable magical abilities but they take time to use. Nagumo’s speed means that he will be able to strike well before any of her songs start to make things dangerous. It’s why having super speed is so handy because at that point it is hard to stop you. Finis would need some kind of automatic barrier or something like that in order to stand a chance here. Nagumo wins.
