Aske opened his eyes, feeling pain all over his body.
It was a terrible encounter, having met someone from the Upper Sequence... he thought with self-mockery.
The so-called Upper Sequence referred to an enemy whose Sequential Ability was nearly identical to yours, but whose Level Rank was higher than yours.
In other words, he had every Extraordinary Ability you did, you couldn't ambush him, and you couldn't defeat him head-on, which naturally made for an exceedingly tough fight.
White-clothed Assassins were among the few professions that could be considered close to the Weapon Master Sequence, and although they could still put up a fight using the Star Nine Forms, the price paid was no small matter.
Even the narrow victory of ultimately killing the opponent in a counter-attack was achieved by leveraging the environment and the mercenary's professional consciousness and operation, trading blows with the enemy until blood was drawn.
