Reid Astrea/Relationships

Anastasia Camp

Julius Juukulius

Julius and Reid shared a rather hostile relationship, despite Julius showing immense respect for the dead Sword Saint. The two battled multiple times. Initially, Julius proved vastly inferior to the Sword Saint, not managing to land even a single strike but after reaching his own resolve and reforming the contract with his Quasi-Spirits-turned-Spirits, the Spirit Knight managed to fight the Sword Saint on equal grounds and eventually even defeating him. Despite that, Reid remarked that if he still had his original body, Julius wouldn't stand a chance and the Knight wholeheartedly agreed on that assessment. In his final moments, The first Sword Saint showed a degree of respect towards Julius, asking for his name and congratulating him on passing the 2nd Trial of the Pleiades Watchtower.

Natsuki Subaru

During the second trial of the Pleiades Watchtower, Reid often referred to Subaru as Fish. Thanks to his vulgar attitude and immeasurable strength, Subaru did not like the first Sword Saint, although he respected his insane strength. Later, during the attack by the siblings Gluttony, once he took over Roy’s body, he looked at Subaru and exclaimed “disgusting”, wondering how he hasn’t gone insane, implying that he had obtained knowledge of Return by Death via Roy. This led to him slaughtering Subaru several times personally.

Royal Family

Farsale Lugunica

According to Alec Hoshin, Farsale and Reid traveled alongside each other on a journey to save the world. It can be assumed that Farsale got along with him due to his friendly personality.

Witch Cult

Lye Batenkaitos

Lye and Reid shared an extremely hostile relationship. Reid usually didn't care about him and showered him with insults like "filthy midget-chan" while Lye tried to come up with an explanation as to why Reid was able to descend from his floor, before rethinking his strategy and ultimately deciding on eating him, which always ended with Lye getting beaten into a pulp and Rui taking over his body. Interestingly enough, not even Lye was able to establish a "normal" conversation with Reid.

Roy Alphard

Roy and Reid also shared a rather hostile relationship with Roy sole goal being to eat the first Sword Saint's name and memories which ended disastrously for the Sin Archbishop as Reid overpowered Roy's existence, taking over his body and achieving complete and utter revival, effectively coming back to life about 400 years after his death. Fortunately, Reid turned out to be incompatible with Roy's body, shattering and dying for the last time.

Witches

Satella

Though the relationship between these two is unknown, according to Alec Hoshin, they traveled together on a trip to save the world. Unfortunately, after Satella descended into madness following her transformation into the Witch of Envy, Reid was forced to team up with Flugel and Volcanica to seal her away.

Echidna

According to Alec Hoshin, she and Reid traveled alongside each other on a journey to save the world.

Others

Flugel

Not much is known about Flugel and Reid's relationship, however, we do know the two of them shared a similar relationship than that of Gian and Suneo from the Doraemon series. From what the author had said, it's safe to assume Flugel was the "brains" and Reid was the "brawn" of the duo. Flugel seemed to have respect for Reid's strength, enough to note him as strong, but also introduced him as a fool in the Pleiades Watchtower Trial.

According to Alec Hoshin, Flugel and Reid traveled alongside each other on a journey to save the world. Unfortunately, they were later forced to work together with Volcanica to seal away the rampaging Satella.

Shaula

Shaula heavily dislikes Reid for his terrible personality and his habit of fondling her. When he appeared as the proctor for the second trial in the Pleiades Watchtower, she would freeze and even faint upon seeing the Sword Saint again.

Volcanica

Though the relationship between these two is unknown, they were willing to team up with each other alongside Flugel to fight against Satella when she was going on her rampage.

Alec Hoshin

According to Hoshin, he traveled alongside Reid on a journey to save the world. He was also under the impression that Reid was the one person in the group least likely to die.
