[Knight 'Igrit' is requesting your permission to advance his grade.]
[Will you permit the advancement?]
'Permission to advance?'
Surprised by the never-before-seen System message, Jin-Woo quickly confirmed Igrit's information to make sure.
[Igrit Lv. Max]
Knight grade.
It's now possible to advance the grade after the level requirement has been met. Will advance to the next grade when the Sovereign gives his permission.
'Igrit's level.....??'
The level that previously hovered around the 30 mark had changed to 'Max' before he had noticed it. It must've been the case that, once the Shadow Soldier's level cap had been met, he'd be given an opportunity to advance to the next grade.
'Is the requirement level for advancement somewhere between the late thirties and early forties?'
When taking into account the potential level-ups happening during a single battle, he suspected that the required level had to be around there somewhere.
TL: As a side note, Japanese names, just like Korean and Chinese, starts off with surname first. "Goto" is the family name, and "Ryuji" is his given name. Same story for Matsumoto Shigeo as well.
