Justus

Justus (ユストクス Yusutokusu) is Ferdinand's attendant and can act as a tax official due to his education as a scholar. He excels in knowledge and information gathering.

Other people usually describe Justus as looking plain, a fact he knows how to use well to blend in with crowds when gathering information.

Spoiler from Part 4 Volume 3 He has a strong resemblance to his mother and sister. Rozemyne even thought that he has "a bit of an androgynous face" once.

When crossdressing he is absolutely convincing as a woman, as long as he is wearing gloves and a scarf or high collar, since his adam's apple and rough hands would likely give him away. He is even able to change his voice and mannerisms to the point of passing perfectly fine as a women.

He is curious about anything and everything. He is more open-minded compared to other nobles, but that is only due to his passion for collecting information.

This passion is so intense there's almost nothing he won't do in the course of information gathering. He openly - and proudly - admitted to once infiltrating a women's tea party dressed as a women without getting caught.

The downside is that he is so obsessed with learning new things that it can not only become off-putting to others, but also override his common sense or even survival instinct, often getting himself and his companions in danger if he's allowed to just go unchecked.

Spoiler from Part 4 Volume 3 Justus enrolled at the academy to become an attendant and successfully graduated in that course. Additionally he also took the scholar's course out of interest. He was also the one from whom Ferdinand learned that it was possible to take multiple courses, if one wanted to.

When Ferdinand became a Blue Priest, Justus could no longer officially work as his attendant, but he kept serving him in a reduced capacity, mostly with tasks usually given to scholars.

Justus and Eckhart are both sent by Ferdinand to investigate Myne and her activities in the lower city. He uses various disguises and even breaks in to the Merchant guild to find out Myne's Workshop.

When Rozemyne began her material gathering, Justus was assigned to accompany her and instruct her.

Upon Ferdinand's return to noble society, Justus is happy to re-enter his service as an official attendant, though Ferdinand rarely allows him to enter the temple itself, despite - or more likely exactly because of - Justus expressing great interest in exploring the temple and the Rozemyne Workshop in particular.

During Rozemyne's first year at the Royal Academy, Justus was assigned as an attendant to Traugott to properly educate him on the proper behaviour of an archnoble after the blunder that saw the boy retire from Rozemyne's service as a guard knight. But that is only part of his duty. Justus was also gather information and advice Rozemyne. He provided valuable advice for the entirety of the Ehrenfest student body on how to best approach the socializing and prepare for the upcoming interduchy tournament.

He also acompanies Rozemyne to a tea-party with Prince Anastasius, disguised as a woman and using his sister's name Gudrun for the occasion, much to Rihyarda's and Traugott's displeasure.

Spoiler from Part 4 Volume 3
 * He calls Rozemyne "hime-sama" which means literally "princess".
 * He adopts Rihyarda's manner of speaking, making them both the only two characters using bochama and hime-sama to refer to certain people.
 * His name was previously translated as "Eustachius" which was adjusted to "Justus" in Part 3 Volume 2.
 * Despite what some people assume about him, he professes that he does not cross-dress because he likes to, but that it is solely the most effective and reliable way to gather information and thus preferable to any of the alternatives like hiring a female scholar.


 * Justus is banned from travelling in Rozemyne's Pandabus as he talks to her too much and she can't concentrate while she is riding her highbeast.
 * Ferdinand is the only person who can use Justus's gathered information to his advantage.
