Dust/Relationships

Rin
It has been implied that Dust has romantic feelings for his party member Rin. His actions would certainly support this notion, as he often goes out of his way to protect Rin and often does what he can to make her happy, even if it is to his own detriment. Her face reminds Dust of the princess of his past, which may partially explain why he is so fond of her. After spending an afternoon with them, Iris assumed they were a couple after seeing how they acted around each other.

Despite all this Dust is not above making rude and inappropriate remarks towards Rin, or trying to sponge money off of her; and the two are often seen bickering like an old married couple. Rin is known around town as Dust's "guardian", as she often bails him out of hairy situations that he has caused; it has gotten to the point where Rin is suspicious when Dust isn't doing anything unsavory.

Whether or not Rin has romantic feelings is left ambiguous, however there is no doubt that she cares deeply for him. After Dust was killed fighting the Cloned Hydra, Rin was incredibly distraught and worried that Aqua couldn't resurrect him, and was very relieved when he was safe. She also didn't seem that bothered by Dust seeing her naked and visa-versa in the Arcanletia mixed baths, though Dust did effectively drug her beforehand to cause that. Moreover, she was reasonably angry afterwards. She was later envious of Faitfore's childish freedom to say that she loves Dust after Faitfore was able to tell Dust that she loved him.

Satou Kazuma
Dust initially disliked Kazuma due to jealousy, being unable to understand why he was always complaining despite being surrounded by three beautiful women with high-tier jobs. Dust's attitude towards Kazuma flipped after adventuring with the latter's party, truly understanding the hardships that Kazuma had to go through daily, and the pair soon became friends.

A lot of Dust's unsavory attitude and activities have rubbed off on Kazuma, the latter taking up gambling due to Dust's influence. Although Dust views Kazuma as his best friend, he still sponges drinks off of him from time-to-time and has admitted that he probably wouldn't help Kazuma out if the latter became short on cash. Kazuma has stated that he only really sees Dust as an acquaintance.

Though in reality while he will never admit he does see Dust as a good and close friend. And Dust trusts Kazuma enough to give him his trusted magic sword.

Aqua
Similarly to the rest of Kazuma's party, Dust originally believed Aqua to be both beautiful and competent. After spending a day partied together with the priestess, Dust's attitude flipped after he realized how useless Aqua was. That being said, Dust seems to hold Aqua in a more positive light then he does with Megumin or Darkness. Dust and Aqua seem to uphold a very similar outlook on life, believing it is okay to depend on others without giving anything in return.

Dust was genuinely thankful when Aqua resurrected him, however this enthusiasm was short lived as he soon found himself extremely annoyed by her. He was one of the few adventurers who stood up for Aqua when Serena muscled in on her turf as the top priestess of Axel, although he later switched to Serena's side when she bribed him with money.

Megumin
Dust's initial impression of Megumin was of a beautiful, sensible, and powerful mage. However as soon as he partied with her for a day he realized that she was almost useless and lacked any common sense. When Dust saw Megumin being tied up by a group of men he presumed it was because she had wronged them in the past (which she had), and refused to bail her out.

Dust's negative feelings towards Megumin are reciprocated, as Megumin detests Dust, seeing him as a bumbling buffoon who is a horrible influence on Kazuma and Yunyun. Despite her apparent disdain for him, Megumin is not above asking Dust to party with her when no one else wants to.

Princess Iris
Dust initially viewed Iris as a snot-nosed brat after she had him arrested for flirting with a woman. His opinion of her improved after spending sometime with her wandering around the Capital, however Dust was still willing to turn her over to the authorities for a sizable reward.

His attitude changed towards Iris after he realized the burden that rested on her shoulders at such a young age, viewing her with the utmost respect and sympathy. Dust was so moved by Iris's attitude that he risked his life by infiltrating the royal castle just to give her a dragon ride.

Faitfore
The relationship between Dust and Faitfore is like that of a father and daughter so much so that he would change his classic delinquent personality to act a little more responsible to take care of it.

Leonor
Dust served as princess Leonor's personal knight during his time as a dragon knight. Opposite of Rein's prim and proper personality, Leonor is very chaotic and irreverent. They would often banter, with Leonor constantly trying to find ways to tease Rein, causing him troubles. Despite this, Rein remains loyal and devoted to her.

Leonor was largely responsible for Rein turning into the delinquent that is Dust. During the week long escape they did from the castle, they went on numerous activities to have fun, and she would demand that Rein adopt a more thug-like personality to hide their identities. She would also expose Rein to gambling, which later turned to addiction.

It is hinted that both Rein and Leonor do have hidden romantic feelings for one another. Despite accepting that Leonor is a princess destined to be betrothed, Rein does consider the possibility of him ending up with the princess. When Leonor and Rein were last together, he was determined to "take her hand and never let go" should she accept his. Meanwhile, Leonor would drops hints that she loves him from time to time, usually quickly hiding it behind a tease. And despite going out of her way to try and avoid marriage every time it was laid in the table, she was quick to agree just to be able to save Rein's life. When Leonor and Rein finally part ways due to him being exiled, Leonor kissed him in the lips before giving him her sword.
