Secilia Morningstar
Short bio: The daughter of Lucifer Morningstar, she was the first person whom Jaune met on his journey into this new world. She is a huge contrast to her father, who is a kind and good-willed soul, while her father is cruel.

Despite not looking like a good fighter, she could summon any demons from Hell or the Ars Goetia to fight for her, but if she wants to get up close and personal, she could kick ass and is skilled in mixed martial arts. 

She soon fell for Jaune after he saved her a couple of times and when they opened up to each other's past.

Sarah Rose Yvangelyte
Short bio: Once a servant under the control and servitude to the Gods to subjugate humanity, she soon broke free from control when she fought Jaune and Secilia, and she joined them after he had killed the Norse Gods.

An experienced Valkyrie, she mostly uses spears as her main weapon, like the Spear of Light, but her most cherished one is Gae Bolg Xyston, a variant of the Gae Bolg that has two spearheads instead of one.

She was then quickly entranced by Jaune's charm, likeness and good-hearted will, falling for him also.

Crimson Scarlet
Short bio: A Ronin from the Land of Japan, initially was suspicious of Jaune and his group, but after they explained their goals to them, she decided to help them fight against the Shinto Gods.

Although not a fully-fledged samurai, she was considered a ronin as she had no master to protect, but that doesn't mean that her swordplay was trash, as she once sliced a rock into two with a single strike without breaking.

Just like the others, she soon fell quickly for Jaune.

Madelyn Valentine
Short bio: Coming from a line of surgeons, Madelyn knows how to restructure your organs into an incoherent mess or torture you by messing with your nerves and shutting them down almost effectively (but she does take her job seriously). 

Although not a combatant, she can still put up a fight, but mostly leaves the fighting to her alter ego: Jack.

Ynesis Orius Knight
Short bio: Once a servant of the gods and their most powerful enforcer, she was then freed of their control after Jaune saved her from another enforcer when she was unconscious. 

She once viewed Jaune's group as nothing but an obstacle to achieving her goal of reuniting with her father, but soon realised that the Gods would dispose of her once she had completed her job, so, joined his group to get back at the Gods and fell for him.

The reason why she was considered the most powerful out of everyone was that she inherited powers to control the galaxy at the tip of her fingers, meaning that she could summon a meteor shower or cause the Moon to collide with the Earth.

Michaela the Fallen
Short bio: A fallen angel serving for the gods as their secondary enforcer, she also was freed of the Gods' control after a fight with Jaune's group. 

Like Ynesis, she wanted to reunite with her brother, but after learning of the Pantheons's true nature and decided to join the fight against them, while falling for Jaune at the same time.

She's capable of twisting any living being into a soulless puppet for her to command and fight, making her a dangerous adversary.

Lily Winterknight
Short bio: A childhood friend of Jaune and Jeanne, they both grew up with each other since their families had close ties with each other. 

Their bond was closely knit with each other to the point that the family knew they had feelings for each other.

However, when Jaune was disowned by the Arc family and the Clan, her clan cut ties with them, which left her feeling depressed about Jaune's disappearance.

Arthuria Pendragon
Info: One of the few people he had summoned from the past, she was the former king of Britannia, while earning herself the King of Knights. Even though the mythos depict her as a male, her true gender identity is hidden thanks to Merlin.

(And just like everybody in his harem, she fell for him soon afterwards as he spent some time training with her)

Morgan Le Faye
Info: The Sister of Arthuria Pendragon, was originally vengeful and jealous of Arthuria taking over as king, thus sparking the iconic Arthurian conflict against each other.

However, in one period of time, she reformed from being evil and the rest is history, until she was also summoned by Jaune, to which she helped him in taking down the gods.

Noir Blanchefforte
Info: Another childhood friend of Jaune, underwent Android augmentation at 16 after an unfortunate incident involving a secret training routine, which resulted in her brain and organs being transported into an artificial body, though for some reason, she asked for rabbit faunus features to be installed.

After she had heard of Jaune's disappearance, she also mourned for him, alongside Lily.
